If you're about to complete, or have ever completed a graduate degree, you have most likely come across the term "thesis defense." In many countries, to finish a graduate degree, you have to write a thesis .

A thesis is a large paper, or multi-chapter work, based on a topic relating to your field of study.

Once you hand in your thesis, you will be assigned a date to defend your work. Your thesis defense meeting usually consists of you and a committee of two or more professors working in your program. It may also include other people, like professionals from other colleges or those who are working in your field.

During your thesis defense, you will be asked questions about your work. The main purpose of your thesis defense is for the committee to make sure that you actually understand your field and focus area.

The questions are usually open-ended and require the student to think critically about their work. By the time of your thesis defense, your paper has already been evaluated. The questions asked are not designed so that you actually have to aggressively "defend" your work; often, your thesis defense is more of a formality required so that you can get your degree.

  • Check with your department about requirements and timing.
  • Re-read your thesis.
  • Anticipate questions and prepare for them.
  • Create a back-up plan to deal with technology hiccups.
  • Plan de-stressing activities both before, and after, your defense.

How long your oral thesis defense is depends largely on the institution and requirements of your degree. It is best to consult your department or institution about this. In general, a thesis defense may take only 20 minutes, but it may also take two hours or more. The length also depends on how much time is allocated to the presentation and questioning part.

Tip: Check with your department or institution as soon as possible to determine the approved length for a thesis defense.

First of all, be aware that a thesis defense varies from country to country. This is just a general overview, but a thesis defense can take many different formats. Some are closed, others are public defenses. Some take place with two committee members, some with more examiners.

The same goes for the length of your thesis defense, as mentioned above. The most important first step for you is to clarify with your department what the structure of your thesis defense will look like. In general, your thesis defense will include:

  • your presentation of around 20-30 minutes
  • questions from the committee
  • questions from the audience (if the defense is public and the department allows it)

You might have to give a presentation, often with Powerpoint, Google slides, or Keynote slides. Make sure to prepare an appropriate amount of slides. A general rule is to use about 10 slides for a 20-minute presentation.

But that also depends on your specific topic and the way you present. The good news is that there will be plenty of time ahead of your thesis defense to prepare your slides and practice your presentation alone and in front of friends or family.

Tip: Practice delivering your thesis presentation in front of family, friends, or colleagues.

You can prepare your slides by using information from your thesis' first chapter (the overview of your thesis) as a framework or outline. Substantive information in your thesis should correspond with your slides.

Make sure your slides are of good quality— both in terms of the integrity of the information and the appearance. If you need more help with how to prepare your presentation slides, both the ASQ Higher Education Brief and James Hayton have good guidelines on the topic.

The committee will ask questions about your work after you finish your presentation. The questions will most likely be about the core content of your thesis, such as what you learned from the study you conducted. They may also ask you to summarize certain findings and to discuss how your work will contribute to the existing body of knowledge.

Tip: Read your entire thesis in preparation of the questions, so you have a refreshed perspective on your work.

While you are preparing, you can create a list of possible questions and try to answer them. You can foresee many of the questions you will get by simply spending some time rereading your thesis.

Here are a few tips on how to prepare for your thesis defense:

You can absolutely prepare for most of the questions you will be asked. Read through your thesis and while you're reading it, create a list of possible questions. In addition, since you will know who will be on the committee, look at the academic expertise of the committee members. In what areas would they most likely be focused?

If possible, sit at other thesis defenses with these committee members to get a feel for how they ask and what they ask. As a graduate student, you should generally be adept at anticipating test questions, so use this advantage to gather as much information as possible before your thesis defense meeting.

Your thesis defense is a formal event, often the entire department or university is invited to participate. It signals a critical rite of passage for graduate students and faculty who have supported them throughout a long and challenging process.

While most universities don't have specific rules on how to dress for that event, do regard it with dignity and respect. This one might be a no-brainer, but know that you should dress as if you were on a job interview or delivering a paper at a conference.

It might help you deal with your stress before your thesis defense to entrust someone with the smaller but important responsibilities of your defense well ahead of schedule. This trusted person could be responsible for:

  • preparing the room of the day of defense
  • setting up equipment for the presentation
  • preparing and distributing handouts

Technology is unpredictable. Life is too. There are no guarantees that your Powerpoint presentation will work at all or look the way it is supposed to on the big screen. We've all been there. Make sure to have a plan B for these situations. Handouts can help when technology fails, and an additional clean shirt can save the day if you have a spill.

One of the scariest aspects of the defense is the possibility of being asked a question you can't answer. While you can prepare for some questions, you can never know exactly what the committee will ask.

There will always be gaps in your knowledge. But your thesis defense is not about being perfect and knowing everything, it's about how you deal with challenging situations. You are not expected to know everything.

James Hayton writes on his blog that examiners will sometimes even ask questions they don't know the answer to, out of curiosity, or because they want to see how you think. While it is ok sometimes to just say "I don't know", he advises to try something like "I don't know, but I would think [...] because of x and y, but you would need to do [...] in order to find out.” This shows that you have the ability to think as an academic.

You will be nervous. But your examiners will expect you to be nervous. Being well prepared can help minimize your stress, but do know that your examiners have seen this many times before and are willing to help, by repeating questions, for example. Dora Farkas at finishyourthesis.com notes that it’s a myth that thesis committees are out to get you.

Two common symptoms of being nervous are talking really fast and nervous laughs. Try to slow yourself down and take a deep breath. Remember what feels like hours to you are just a few seconds in real life.

  • Try meditational breathing right before your defense.
  • Get plenty of exercise and sleep in the weeks prior to your defense.
  • Have your clothes or other items you need ready to go the night before.
  • During your defense, allow yourself to process each question before answering.
  • Go to dinner with friends and family, or to a fun activity like mini-golf, after your defense.

Allow yourself to process each question, respond to it, and stop talking once you have responded. While a smile can often help dissolve a difficult situation, remember that nervous laughs can be irritating for your audience.

We all make mistakes and your thesis defense will not be perfect. However, careful preparation, mindfulness, and confidence can help you feel less stressful both before, and during, your defense.

Finally, consider planning something fun that you can look forward to after your defense.

It is completely normal to be nervous. Being well prepared can help minimize your stress, but do know that your examiners have seen this many times before and are willing to help, by repeating questions for example if needed. Slow yourself down, and take a deep breath.

Your thesis defense is not about being perfect and knowing everything, it's about how you deal with challenging situations. James Hayton writes on his blog that it is ok sometimes to just say "I don't know", but he advises to try something like "I don't know, but I would think [...] because of x and y, you would need to do [...] in order to find out".

Your Powerpoint presentation can get stuck or not look the way it is supposed to do on the big screen. It can happen and your supervisors know it. In general, handouts can always save the day when technology fails.

  • Dress for success.
  • Ask for help setting up.
  • Have a backup plan (in case technology fails you).
  • Deal with your nerves.

How To Prepare For Your Thesis Defense

If you are conducting post-graduate research within your discipline, you will come across the phrase “thesis defense”. A thesis defense is part of the things you will need to accomplish before acquiring a postgraduate degree. 

The thesis defense comes at the end of the graduate program. It is used to determine or define your education milestone while in the university. For this, you need a thesis defense comprehensive guide to be outstanding.

How Long does a Thesis Defense Take?

On average, a thesis defense takes somewhere between 30 minutes and one hour. However, the time it takes to do a thesis defense depends on the academic level you are in.

While there is no standard or general length for a thesis defense, post-graduate sessions will take longer compared to undergraduate sessions.

Yes, some institutions, professors, or some disciplines may require you to do a thesis defense at your undergraduate level. But the length of the presentation depends on your academic level.

What is Thesis Defense?

Defending your thesis

A thesis defense is an act of presenting your academic work to a panel or committee of professors and other involved scholars. From this, they can gauge or grade your abilities in presenting your work.

The arguments presented during the thesis defense are to ascertain that you have understood the course and your selected topic.

You will have to first hand in your work or paper to the professor for grading. Thereafter, you will be summoned for thesis defense.

When summoned for a thesis defense, you will be required to answer all the questions presented to you by the panel of professors. After this, you will be required to leave the room. The panel is to decide whether your paper or thesis is ready for publication. In addition, the panel checks whether your work needs corrections. 

In other words, a thesis defense is a forum that allows postgraduate students to defend the topic of their thesis before a panel of professors. Therefore, the thesis defense is part of the requirements that postgraduate students must accomplish to receive advanced degrees in whichever academic disciplines they pursue.

Factors that Determine the Length of a Thesis Defense

Just like a dissertation that you have to write a thesis , it is important that you will have to present it. The time is taken to do this varies. The following four factors determine the length of a thesis defense

Determining the length of thesis defense

  • As noted earlier, the level of education will determine the length of your thesis defense.
  • The second factor is the institutional requirements. Some institutions will have a specified amount of time allocated for a thesis defense. In some institutions, that time is longer than and vice versa.

Very recognized institutions of higher learning will have the autonomy to decide on the length of a thesis defense.

  • The third factor that will determine the length of a thesis defense is the consensus of the panel of professors. Some will give students very limited time to do a thesis defense while others will give more time to their students.

Some institutions, scholars, applaud limiting the amount of time for thesis defense and educators because it gauges the student’s ability to accurately defend their work within a short time. If they succeed, then they are good learners.

  • Another factor determining the time of a thesis defense is the academic discipline that is explored by the topic.

While every academic discipline deserves respect, they are not the same in terms of the complexity of the concepts and what the student covers.

Some disciplines will require students to come up with much longer papers. This means that the time it could take to do a thesis defense will be longer. 

From the aforementioned factors, it is evident that it would be difficult to predetermine the standard length of a thesis without holding some parameters or factors constant such as the academic level of the thesis. 

Also, the length of your dissertation or thesis determines the time you will take to present it at your defense session. Longer documents will take you longer to defend.

How to Defend a Thesis – 5 Comprehensive Steps

Some steps can help you defend your thesis effectively. You should follow the steps below if you are summoned by a panel of professors to defend your thesis. 

1. Adequate Preparation

preparing for thesis defense

When you are required to defend your thesis, you will be given a specific date you will appear before the panel of professors for the actual exercise.

As long as you have submitted your paper to the professor for grading, you should always be aware that you will have to defend your thesis.

Therefore, between the period of submitting your paper and the date provided for thesis defense, you should do adequate preparation.

Students will have several months to prepare for a thesis defense. This is because the institutions themselves want their students to be well prepared before they meet the panel of professors.

After all, they would wish their students to excel in their studies. As noted, there will be a specified date for the thesis defense. Therefore, it will not surprise their committee members or students when the time comes for defending the thesis. 

Adequate preparation entails knowing or rather anticipating what is required of you. You should be prepared for the kinds of questions your thesis topic will provoke from the panel and practice on them.

When you have the right attitude and have adequately prepared for the thesis defense, it would be nearly impossible to fail. Also, be prepared to wear decently during the defense. 

2. Carry an In-Depth Knowledge of the Thesis

This is a very important step when defending your thesis. Since you are the one who has written the paper, you should be fully aware of the topic and the contents of your paper. What this means is that you should adequately research the topic of your thesis so that you can be ready for any question you are asked by the panel of professors.

For a postgraduate student who wishes to master their discipline, it would be a shame if you do not know about your topic.

For example, if you are within the field of environmental sciences and have written your paper based on the discipline, you should narrow down the scope of your knowledge to that of your topic, the topic of your paper should act as the guide to the amount of knowledge you are supposed to give for the sake of the thesis defense.

Avoid too much knowledge because it may overwhelm you. At the same time, do not narrow down the scope of your topic too much because you will have limited knowledge during the thesis defense.

Your instructor or professor can help you in terms of giving you direction on the type and scope of knowledge you are required to have during a thesis defense. 

3. Prepare an Introduction

writing resources for thesis defense introduction

Have you ever heard of the first impression and its significance?

The first impression of a person will determine how the other person will perceive them.

If it is terrible, the other person may consider them a terrible person and even dislike them.

An introduction plays the same role as the “first impression” of your thesis defense to the panel of professors.

You should prepare a good introduction that should summarize the contents of your paper, the reasons why you selected the topic and its relevance to the discipline, and any other detail that you will anticipate to be asked during the thesis defense.

Make sure that the thesis is crystal clear and concise to avoid making any contradictions of your topic and confusing the panel.

Since you will be given several months to prepare for your thesis defense, take time to refine your introduction.

Make adjustments or corrections whenever necessary so that you will have a perfect introduction for your thesis defense. You may recite the introduction or carry it with you if the panel will allow it. 

4. Making the Actual Presentation

The action presentation of the thesis defense is quite scary to many students. This is because you will have to face a panel of professors to defend your paper. Based on your paper’s content, you will answer several questions.

Therefore, if you fail during the actual presentation, your paper may not be published and you will have to do further revisions. 

During the actual presentation, you should be well dressed because grooming tells a lot about the character of a student. Carry the necessary equipment you will require during the presentation. Such equipment can include a laptop that contains a PowerPoint presentation, a pen, and a notebook.

The PowerPoint presentation should be legible, objective, and strategically written to maximize the time used to defend your thesis. Ensure that you arrive early to the place where you will face the panel of professors to give you time to reflect and lessen your anxiety.  

As aforementioned, adequate preparation, understanding your topic or thesis, and a good attitude will guarantee success. Therefore, if you adhere to the aforementioned guidelines during the presentation, there is a high probability that your paper will be published. 

5. Do a Good Conclusion

Doing a good introduction and effectively presenting your defense is not enough without an equally good conclusion. Just like you took a good time to write your thesis , you will also need a good time to write a presentation and a good conclusion.

A good conclusion of your presentation leaves the panel of professors with a good impression of you and your overall ability to defend your work within the academic community. 

A good conclusion will sum up your work. What this means is that you should include a summary of the topic’s background, the literature review, the methodologies, the findings, and the discussions. Make sure that the conclusion compresses the details of your paper logically. It should be brief and straight to the point.

Finally, the conclusion of your thesis defense should clearly describe the limitations or setbacks encountered while you were conducting the study.

Even though you are trying to show that you are a good post-graduate student, it is important to be clear about the limitations. This will demonstrate your academic integrity and ability to conduct actual research in the field.

Tips on How to do a Good Thesis Defense

A good score

1. Anticipate the Questions 

As aforementioned, you should anticipate the questions you may be asked by the panel and prepare for them.

The questions’ base is on your thesis. As such, you should go through your paper and list the possible questions.

At the same time, the academic expertise of the committee members determines the types of questions you may be asked.

Try to have an informed idea, based on your paper, on the areas to receive much focus. 

2. Dress for Success

Do you remember that we have talked about first impressions? Well, your dress code and overall grooming will have a degree of impact on the outcomes of your presentation. Dress well.

Mostly, you are required to dress in an official attire because you are going to do a presentation to a panel of academic experts. You should try as much as possible not to wear casual or provocative clothes. 

3. Delegate

To avoid being overwhelmed during the day of your presentation, you can delegate some of the less complicated activities to a trusted person or friend.

The activities that you can delegate include setting up the equipment you will use for your presentation or distributing handouts to the panel. 

4. Create a Backup Plan

This especially involves the mode of presenting your defense. Since you will be using your laptop and a projector, they may fail during the presentation. It is therefore important to have a plan B. such can include having printed handouts.

Defending Your Dissertation: A Guide

A woman in front of a bookshelf speaking to a laptop

Written by Luke Wink-Moran | Photo by insta_photos

Dissertation defenses are daunting, and no wonder; it’s not a “dissertation discussion,” or a “dissertation dialogue.” The name alone implies that the dissertation you’ve spent the last x number of years working on is subject to attack. And if you don’t feel trepidation for semantic reasons, you might be nervous because you don’t know what to expect. Our imaginations are great at making The Unknown scarier than reality. The good news is that you’ll find in this newsletter article experts who can shed light on what dissertations defenses are really like, and what you can do to prepare for them.

The first thing you should know is that your defense has already begun. It started the minute you began working on your dissertation— maybe even in some of the classes you took beforehand that helped you formulate your ideas. This, according to Dr. Celeste Atkins, is why it’s so important to identify a good mentor early in graduate school.

“To me,” noted Dr. Atkins, who wrote her dissertation on how sociology faculty from traditionally marginalized backgrounds teach about privilege and inequality, “the most important part of the doctoral journey was finding an advisor who understood and supported what I wanted from my education and who was willing to challenge me and push me, while not delaying me.  I would encourage future PhDs to really take the time to get to know the faculty before choosing an advisor and to make sure that the members of their committee work well together.”

Your advisor will be the one who helps you refine arguments and strengthen your work so that by the time it reaches your dissertation committee, it’s ready. Next comes the writing process, which many students have said was the hardest part of their PhD. I’ve included this section on the writing process because this is where you’ll create all the material you’ll present during your defense, so it’s important to navigate it successfully. The writing process is intellectually grueling, it eats time and energy, and it’s where many students find themselves paddling frantically to avoid languishing in the “All-But-Dissertation” doldrums. The writing process is also likely to encroach on other parts of your life. For instance, Dr. Cynthia Trejo wrote her dissertation on college preparation for Latin American students while caring for a twelve-year-old, two adult children, and her aging parents—in the middle of a pandemic. When I asked Dr. Trejo how she did this, she replied:

“I don’t take the privilege of education for granted. My son knew I got up at 4:00 a.m. every morning, even on weekends, even on holidays; and it’s a blessing that he’s seen that work ethic and that dedication and the end result.”

Importantly, Dr. Trejo also exercised regularly and joined several online writing groups at UArizona. She mobilized her support network— her partner, parents, and even friends from high school to help care for her son.

The challenges you face during the writing process can vary by discipline. Jessika Iwanski is an MD/PhD student who in 2022 defended her dissertation on genetic mutations in sarcomeric proteins that lead to severe, neonatal dilated cardiomyopathy. She described her writing experience as “an intricate process of balancing many things at once with a deadline (defense day) that seems to be creeping up faster and faster— finishing up experiments, drafting the dissertation, preparing your presentation, filling out all the necessary documents for your defense and also, for MD/PhD students, beginning to reintegrate into the clinical world (reviewing your clinical knowledge and skill sets)!”

But no matter what your unique challenges are, writing a dissertation can take a toll on your mental health. Almost every student I spoke with said they saw a therapist and found their sessions enormously helpful. They also looked to the people in their lives for support. Dr. Betsy Labiner, who wrote her dissertation on Interiority, Truth, and Violence in Early Modern Drama, recommended, “Keep your loved ones close! This is so hard – the dissertation lends itself to isolation, especially in the final stages. Plus, a huge number of your family and friends simply won’t understand what you’re going through. But they love you and want to help and are great for getting you out of your head and into a space where you can enjoy life even when you feel like your dissertation is a flaming heap of trash.”

While you might sometimes feel like your dissertation is a flaming heap of trash, remember: a) no it’s not, you brilliant scholar, and b) the best dissertations aren’t necessarily perfect dissertations. According to Dr. Trejo, “The best dissertation is a done dissertation.” So don’t get hung up on perfecting every detail of your work. Think of your dissertation as a long-form assignment that you need to finish in order to move onto the next stage of your career. Many students continue revising after graduation and submit their work for publication or other professional objectives.

When you do finish writing your dissertation, it’s time to schedule your defense and invite friends and family to the part of the exam that’s open to the public. When that moment comes, how do you prepare to present your work and field questions about it?

“I reread my dissertation in full in one sitting,” said Dr. Labiner. “During all my time writing it, I’d never read more than one complete chapter at a time! It was a huge confidence boost to read my work in full and realize that I had produced a compelling, engaging, original argument.”

There are many other ways to prepare: create presentation slides and practice presenting them to friends or alone; think of questions you might be asked and answer them; think about what you want to wear or where you might want to sit (if you’re presenting on Zoom) that might give you a confidence boost. Iwanksi practiced presenting with her mentor and reviewed current papers to anticipate what questions her committee might ask.  If you want to really get in the zone, you can emulate Dr. Labiner and do a full dress rehearsal on Zoom the day before your defense.

But no matter what you do, you’ll still be nervous:

“I had a sense of the logistics, the timing, and so on, but I didn’t really have clear expectations outside of the structure. It was a sort of nebulous three hours in which I expected to be nauseatingly terrified,” recalled Dr. Labiner.

“I expected it to be terrifying, with lots of difficult questions and constructive criticism/comments given,” agreed Iwanski.

“I expected it to be very scary,” said Dr. Trejo.

“I expected it to be like I was on trial, and I’d have to defend myself and prove I deserved a PhD,” said Dr Atkins.

And, eventually, inexorably, it will be time to present.  

“It was actually very enjoyable” said Iwanski. “It was more of a celebration of years of work put into this project—not only by me but by my mentor, colleagues, lab members and collaborators! I felt very supported by all my committee members and, rather than it being a rapid fire of questions, it was more of a scientific discussion amongst colleagues who are passionate about heart disease and muscle biology.”

“I was anxious right when I logged on to the Zoom call for it,” said Dr. Labiner, “but I was blown away by the number of family and friends that showed up to support me. I had invited a lot of people who I didn’t at all think would come, but every single person I invited was there! Having about 40 guests – many of them joining from different states and several from different countries! – made me feel so loved and celebrated that my nerves were steadied very quickly. It also helped me go into ‘teaching mode’ about my work, so it felt like getting to lead a seminar on my most favorite literature.”

“In reality, my dissertation defense was similar to presenting at an academic conference,” said Dr. Atkins. “I went over my research in a practiced and organized way, and I fielded questions from the audience.

“It was a celebration and an important benchmark for me,” said Dr. Trejo. “It was a pretty happy day. Like the punctuation at the end of your sentence: this sentence is done; this journey is done. You can start the next sentence.”

If you want to learn more about dissertations in your own discipline, don’t hesitate to reach out to graduates from your program and ask them about their experiences.

Dissertation Defense: Steps To Follow To Succeed

dissertation defense

A dissertation defense is arguably one of the most important milestones in every student’s career. While it signals that your tenure as a student is soon about to close, it validates all your efforts towards your thesis.

Being cautious about including all the necessary details is very important to successfully complete your dissertation proposal defense. This article tells you everything that you need to know about writing a defense that can add great credibility to you as a student.

What is A Dissertation Defense?

The first thing that you need to learn is what is a dissertation defense and what is its purpose. In simple terms, it is a presentation made by a student to defend all the ideas and views that are presented in a dissertation.

The presenter must include details like what is the reason for choosing specific research methods, the theory that has been selected for the paper, and other such points. This presentation is made before an audience that comprises of the university committee, professors and even fellow-students. It is met with questions and answers that gives the student an opportunity to provide more clarity on the dissertation in order to convince the committee to approve it.

Stages of a Dissertation Defense

One of the most important dissertation defense tips provided by several professors is to breakdown the process into three steps:

  • Preparation : This stage involves collection of all the necessary information that must be included in the defense dissertation and making all the arrangements for the actual meeting.
  • The defense meeting : This is where you decide how you will present the defense. The actual meeting is hugely reliant on the performance, body language and the confidence in your oral defense.
  • After the defense meeting : This stage, also known as the follow up, requires you to make the necessary revisions suggested by the university committee. You can even provide bound copies of the whole dissertation to distribute among different members of your departments. In the follow up stage, one must also think about expense that are related to publishing the Ph.D. dissertation defense as well as printing additional copies of the manuscript, if required.

How Long is a Dissertation Defense?

The first thing that a student should know is how long does a dissertation defense last? The length has to be carefully calculated to make the impact that you want. One of the most important steps in the dissertation preparation is to understand how much time each department allocates to the closing oral defense. When you plan in the early stages of your dissertation itself, you can write it in a manner that allows you to defend it in the allocated time.

Usually these meetings including the presentation, the oral defense and the question and answer session last for about two hours. In most cases, these two hours also encompass the time needed by members of the committee to deliberate.

How to Prepare for the Dissertation Defense

Now that you know how long is a dissertation defense, the next step is to prepare well enough to make your presentation impressive.

Here are some tips on how to prepare for a dissertation defense:

  • Watch other students in action to learn about different presentation styles. You can attend defenses of different colleagues in your department as well as other departments in your university.
  • Get all the details about the deadlines and the rules of your college or university about scheduling your defense.
  • Scheduling is also a very important part of your preparation. It is important to note that members of the committee and University chairs need to make time for these defences in a very packed schedule. Coordinate the date, venue and time of your defense as early as possible.
  • Prepare a manuscript adhering to the necessary formatting rules. Review your manuscript thoroughly before you hand it in. During your PH.D, your faculty will also assist you with the defense. For this, they must have a crisp and polished copy of your manuscript.
  • Most colleges have the facility for a pre-defense meeting. This is the best opportunity to sort out any concerns that you may have about the actual meeting. It is a good idea to ask the chairs what types of questions may be put forward and if there are any problems with the defense that need to be resolved. When you prepare for a pre-defense meeting, think of it as the final one and give it your all.
  • Put together all the material that you need for the defense. A detailed, yet to-the-point presentation must be prepared.
  • The final stage of preparation is practicing your presentation over and over again. It is not just the presentation but also the approach towards the questions that you must practice.

Tips To Nail Your Actual Meeting

With these tips you will be one step closer towards a successful defense that will help your dissertation pass and be approved:

  • All meetings should begin by addressing the chair. Make sure you thank all the committee members and the advisors for the efforts that they have put it. This gives you a professional start to the presentation.
  • The presentation should cover the following subjects in brief:
  • The research topic
  • Literature review
  • The methods used for analysis
  • The primary findings of the research
  • Recommendations of additional research on the subject in the focus.
  • Do not get rattled by any discussions among the chairs. They will deliberate on any disagreements or topics of interest. This is a part of the process and is not a reflection of the presentation itself.
  • There are two questions that are commonly asked that you should be prepared for. This includes the weaknesses of the dissertation and the research plans that you have made post-dissertation.
  • Use subtle gestures when you are talking. Do not overuse your hands when doing so. The whole meeting including the question and answer session should have a very formal appeal.
  • The tone of your voice must be assertive without making it seem like you are trying to hard. Be clear and enunciate when you speak.

Once the questions have been answered, the committee will leave the room. Then, after the deliberation, you will be informed if your dissertation has passed or not.

Preparing For Your Dissertation Defense

13 Key Questions To Expect In The Viva Voce

By: Derek Jansen (MBA) & David Phair (PhD) . Reviewed By: Dr Eunice Rautenbach | June 2021

Preparing for your dissertation or thesis defense (also called a “viva voce”) is a formidable task . All your hard work over the years leads you to this one point, and you’ll need to defend yourself against some of the most experienced researchers you’ve encountered so far.

It’s natural to feel a little nervous.

In this post, we’ll cover some of the most important questions you should be able to answer in your viva voce, whether it’s for a Masters or PhD degree. Naturally, they might not arise in exactly the same form (some may not come up at all), but if you can answer these questions well, it means you’re in a good position to tackle your oral defense.

Dissertation and thesis defense 101

Viva Voce Prep: 13 Essential Questions

  • What is your study about and why did you choose to research this in particular?
  • How did your research questions evolve during the research process?
  • How did you decide on which sources to include in your literature review?
  • How did you design your study and why did you take this approach?
  • How generalisable and valid are the findings?
  • What were the main shortcomings and limitations created by your research design?
  • How did your findings relate to the existing literature?
  • What were your key findings in relation to the research questions?
  • Were there any findings that surprised you?
  • What biases may exist in your research?
  • How can your findings be put into practice?
  • How has your research contributed to current thinking in the field?
  • If you could redo your research, how would you alter your approach?

#1: What is your study about and why did you choose to research this in particular?

This question, a classic party starter, is pretty straightforward.

What the dissertation or thesis committee is assessing here is your ability to clearly articulate your research aims, objectives and research questions in a concise manner. Concise is the keyword here – you need to clearly explain your research topic without rambling on for a half-hour. Don’t feel the need to go into the weeds here – you’ll have many opportunities to unpack the details later on.

In the second half of the question, they’re looking for a brief explanation of the justification of your research. In other words, why was this particular set of research aims, objectives and questions worth addressing? To address this question well in your oral defense, you need to make it clear what gap existed within the research and why that gap was worth filling.

#2: How did your research questions evolve during the research process?

Good research generally follows a long and winding path . It’s seldom a straight line (unless you got really lucky). What they’re assessing here is your ability to follow that path and let the research process unfold.

Specifically, they’ll want to hear about the impact that the literature review process had on you in terms of shaping the research aims, objectives and research questions . For example, you may have started with a certain set of aims, but then as you immersed yourself in the literature, you may have changed direction. Similarly, your initial fieldwork findings may have turned out some unexpected data that drove you to adjust or expand on your initial research questions.

Long story short – a good defense involves clearly describing your research journey , including all the twists and turns. Adjusting your direction based on findings in the literature or the fieldwork shows that you’re responsive , which is essential for high-quality research.

You will need to explain the impact of your literature review in the defense

#3: How did you decide on which sources to include in your literature review?

A comprehensive literature review is the foundation of any high-quality piece of research. With this question, your dissertation or thesis committee are trying to assess which quality criteria and approach you used to select the sources for your literature review.

Typically, good research draws on both the seminal work in the respective field and more recent sources . In other words, a combination of the older landmark studies and pivotal work, along with up-to-date sources that build on to those older studies. This combination ensures that the study has a rock-solid foundation but is not out of date.

So, make sure that your study draws on a mix of both the “classics” and new kids on the block, and take note of any major evolutions in the literature that you can use as an example when asked this question in your viva voce.

#4: How did you design your study and why did you take this approach?

This is a classic methodological question that you can almost certainly expect in some or other shape.

What they’re looking for here is a clear articulation of the research design and methodology, as well as a strong justification of each choice . So, you need to be able to walk through each methodological choice and clearly explain both what you did and why you did it. The why is particularly important – you need to be able to justify each choice you made by clearly linking your design back to your research aims, objectives and research questions, while also taking into account practical constraints.

To ensure you cover every base, check out our research methodology vlog post , as well as our post covering the Research Onion .

You have to justify every choice in your dissertation defence

#5: How generalizable and valid are the findings?

This question is aimed at specifically digging into your understanding of the sample and how that relates to the population, as well as potential validity issues in your methodology.

To answer question this well, you’ll need to critically assess your sample and findings and consider if they truly apply to the entire population, as well as whether they assessed what they set out to. Note that there are two components here – generalizability and validity . Generalizability is about how well the sample represents the population. Validity is about how accurately you’ve measured what you intended to measure .

To ace this part of your dissertation defense, make sure that you’re very familiar with the concepts of generalizability , validity and reliability , and how these apply to your research. Remember, you don’t need to achieve perfection – you just need to be aware of the strengths and weaknesses of your research (and how the weaknesses could be improved upon).

#6: What were the main shortcomings and limitations created by your research design?

This question picks up where the last one left off.

As I mentioned, it’s perfectly natural that your research will have shortcomings and limitations as a result of your chosen design and methodology. No piece of research is flawless. Therefore, a good dissertation defense is not about arguing that your work is perfect, but rather it’s about clearly articulating the strengths and weaknesses of your approach.

To address this question well, you need to think critically about all of the potential weaknesses your design may have, as well as potential responses to these (which could be adopted in future research) to ensure you’re well prepared for this question. For a list of common methodological limitations, check out our video about research limitations here .

#7: How did your findings relate to the existing literature?

This common dissertation defense question links directly to your discussion chapter , where you would have presented and discussed the findings in relation to your literature review.

What your dissertation or thesis committee is assessing here is your ability to compare your study’s findings to the findings of existing research . Specifically, you need to discuss which findings aligned with existing research and which findings did not. For those findings that contrasted against existing research, you should also explain what you believe to be the reasons for this.

As with many questions in a viva voce, it’s both the what and the why that matter here. So, you need to think deeply about what the underlying reasons may be for both the similarities and differences between your findings and those of similar studies.

Your dissertation defense needs to compare findings

#8: What were your key findings in relation to the research questions?

This question is similar to the last one in that it too focuses on your research findings. However, here the focus is specifically on the findings that directly relate to your research questions (as opposed to findings in general).

So, a good way to prepare for this question is to step back and revisit your research questions . Ask yourself the following:

  • What exactly were you asking in those questions, and what did your research uncover concerning them?
  • Which questions were well answered by your study and which ones were lacking?
  • Why were they lacking and what more could be done to address this in future research?

Conquering this part dissertation defense requires that you focus squarely on the research questions. Your study will have provided many findings (hopefully!), and not all of these will link directly to the research questions. Therefore, you need to clear your mind of all of the fascinating side paths your study may have lead you down and regain a clear focus on the research questions .

#9: Were there any findings that surprised you?

This question is two-pronged.

First, you should discuss the surprising findings that were directly related to the original research questions . Going into your research, you likely had some expectations in terms of what you would find, so this is your opportunity to discuss the outcomes that emerged as contrary to what you initially expected. You’ll also want to think about what the reasons for these contrasts may be.

Second, you should discuss the findings that weren’t directly related to the research questions, but that emerged from the data set . You may have a few or you may have none – although generally there are a handful of interesting musings that you can glean from the data set. Again, make sure you can articulate why you find these interesting and what it means for future research in the area.

What the committee is looking for in this type of question is your ability to interpret the findings holistically and comprehensively , and to respond to unexpected data. So, take the time to zoom out and reflect on your findings thoroughly.

Discuss the findings in your defense

#10: What biases may exist in your research?

Biases… we all have them.

For this question, you’ll need to think about potential biases in your research , in the data itself but also in your interpretation of the data. With this question, your committee is assessing whether you have considered your own potential biases and the biases inherent in your analysis approach (i.e. your methodology). So, think carefully about these research biases and be ready to explain how these may exist in your study.

In an oral defense, this question is often followed up with a question on how the biases were mitigated or could be mitigated in future research. So, give some thought not just to what biases may exist, but also the mitigation measures (in your own study and for future research).

#11: How can your findings be put into practice?

Another classic question in the typical viva voce.

With this question, your committee is assessing your ability to bring your findings back down to earth and demonstrate their practical value and application. Importantly, this question is not about the contribution to academia or the overall field of research (we’ll get to that next) – it is specifically asking about how this newly created knowledge can be used in the real world.

Naturally, the actionability of your findings will vary depending on the nature of your research topic. Some studies will produce many action points and some won’t. If you’re researching marketing strategies within an industry, for example, you should be able to make some very specific recommendations for marketing practitioners in that industry.

To help you flesh out points for this question, look back at your original justification for the research (i.e. in your introduction and literature review chapters). What were the driving forces that led you to research your specific topic? That justification should help you identify ways in which your findings can be put into practice.

#12: How has your research contributed to current thinking in the field?

While the previous question was aimed at practical contribution, this question is aimed at theoretical contribution . In other words, what is the significance of your study within the current body of research? How does it fit into the existing research and what does it add to it?

This question is often asked by a field specialist and is used to assess whether you’re able to place your findings into the research field to critically convey what your research contributed. This argument needs to be well justified – in other words, you can’t just discuss what your research contributed, you need to also back each proposition up with a strong why .

To answer this question well, you need to humbly consider the quality and impact of your work and to be realistic in your response. You don’t want to come across as arrogant (“my work is groundbreaking”), nor do you want to undersell the impact of your work. So, it’s important to strike the right balance between realistic and pessimistic .

This question also opens the door to questions about potential future research . So, think about what future research opportunities your study has created and which of these you feel are of the highest priority.

Discuss your contribution in your thesis defence

#13: If you could redo your research, how would you alter your approach?

This question is often used to wrap up a viva voce as it brings the discussion full circle.

Here, your committee is again assessing your ability to clearly identify and articulate the limitations and shortcomings of your research, both in terms of research design and topic focus . Perhaps, in hindsight, it would have been better to use a different analysis method or data set. Perhaps the research questions should have leaned in a slightly different direction. And so on.

This question intends to assess whether you’re able to look at your work critically , assess where the weaknesses are and make recommendations for the future . This question often sets apart those who did the research purely because it was required, from those that genuinely engaged with their research. So, don’t hold back here – reflect on your entire research journey ask yourself how you’d do things differently if you were starting with a  blank canvas today.

Recap: The 13 Key Dissertation Defense Questions

To recap, here are the 13 questions you need to be ready for to ace your dissertation or thesis oral defense:

As I mentioned, this list of dissertation defense questions is certainly not exhaustive – don’t assume that we’ve covered every possible question here. However, these questions are quite likely to come up in some shape or form in a typical dissertation or thesis defense, whether it’s for a Master’s degree, PhD or any other research degree. So, you should take the time to make sure you can answer them well.

Dissertation Defense

thesis defense length

What is a dissertation defense?

The final oral examination for a doctoral candidate, commonly known as the dissertation defense, represents the conclusive formal stage prior to the submission of the dissertation manuscript and the conferral of the doctoral degree. This examination centers on the dissertation itself and its relevance within the candidate's area of academic specialization.

A successful defense is the peak of your academic career, so don’t treat it lightly. Make sure that you take enough time to learn everything there is to know about the topic and prepare well. If you look at your paper and it seems raw or unfinished, and especially if your academic advisor says so, it might be best to take another semester for prep. We don’t mean to scare you, but it truly is a responsible moment, and if you fail your defense, all the years of hard work will be wasted.

Defending doctoral dissertation is not going to be easy. If you don’t get to choose the members of your board and you will be met with unfamiliar faces, you might start to panic and feel lost. This is exactly why you need to be over-prepared. In fact, there’s no such thing as being overly prepared when it comes to your defense. Think of all the possible questions your dissertation committee members may have, even the most far-fetched ones, and then find the answers.

Doctoral dissertation defense process

During the dissertation defense, the candidate delivers an oral presentation of their dissertation to the Supervisory Committee (refer to the Supervisory Committee Policy) and to a public audience. The length of both the oral presentation and the subsequent question-and-answer session is determined through consultation between the Committee and the candidate, ensuring it meets the specific requirements and standards of the process.

The dissertation defense process, often the culmination of a doctoral program, is a critical step in the journey towards earning a PhD or similar advanced degree. This process involves several key stages designed to assess the quality, originality, and contribution of the candidate's research. Here's a general overview:

  • Completion of the Dissertation : Before the defense can be scheduled, the dissertation must be completed. This involves conducting original research, writing up the findings, and often, revising the document based on the advisor's feedback.
  • Submission of the Dissertation : Once the dissertation is completed and approved by the advisor, it must be submitted to the department or dissertation committee for review. This submission typically includes a written document detailing the candidate's research findings and conclusions.
  • Scheduling the Defense : After the dissertation is submitted, a defense date is scheduled. The timing of this can vary widely depending on the institution and the specific requirements of the department.
  • Preparation for the Defense : The candidate prepares a formal presentation of their research findings. This presentation is typically structured to highlight the research question, methodology, key findings, and the significance of the work.
  • The Defense Event : The defense itself is a public forum in which the candidate presents their research to the dissertation committee and often, an audience of peers, faculty, and sometimes the general public. Following the presentation, committee members and sometimes audience members ask questions related to the research and the findings.
  • Question and Answer Session : This session allows the committee to probe the candidate's understanding of the research area, methodology, and conclusions. The candidate must defend their research choices and conclusions, demonstrating deep knowledge of the subject.
  • Committee Deliberation : Following the Q&A, the committee deliberates in private to decide whether the candidate has successfully defended the dissertation. Criteria for success can include the originality of the research, the soundness of the methodology, and the significance of the contributions to the field.
  • Outcome Announcement : The committee then informs the candidate of the outcome. Possible outcomes can include pass, pass with minor revisions, pass with major revisions, or fail, although specifics can vary by institution.
  • Completion of Revisions (if required) : If the committee requires revisions, the candidate must complete these before the degree can be officially awarded. The scope of revisions can vary significantly.
  • Final Submission : After any required revisions are made and approved by the committee, the final version of the dissertation is submitted to the university. This often includes submitting bound copies of the dissertation and making it available through the university's library or institutional repository.
  • Graduation and Degree Conferral : Following successful defense and submission of the final dissertation, the candidate is eligible to graduate and receive their doctoral degree.

This process is a significant milestone in an academic career, representing the transition from student to scholar and contributing new knowledge to the field.

Even though it may seem horrible and nerve-racking, the process of defending your dissertation is pretty straightforward. And if you take your time to prepare for it well, you will not have any problems with the defense itself.

The scariest part is presenting your work to a group of professionals. You have to show your proficiency in the field, ability to think critically and withstand criticism. Most colleges and universities will allow you to choose your own committee. So, try to take your pick as early as possible so you’re not left with people the rest of your group didn’t want. 

How to defend dissertation?

Navigating your dissertation defense involves thorough prep, including understanding your institution's format, mastering your material, anticipating committee questions, and perfecting your presentation. During the defense, remain poised, address inquiries with depth, and interact professionally. Post-defense, be ready for revisions. Ensure professional attire, early arrival, and confidence in your expertise. Embrace feedback as growth. Celebrate this significant academic milestone, as it's not only an examination but a showcase of your scholarly journey.

Defending your dissertation is a pivotal moment in your academic career. Here's a step-by-step guide to prepare for and successfully defend your dissertation:

Let’s assume that your dissertation paper is done and approved. The next step after choosing your committee would be preparation. In one of the committee meetings, you will discuss how much time you have for your defense and the Q&A session afterward. Normally, the whole defense lasts about an hour, but it can vary depending on the number of doctoral students defending on the same day. 

Preparing for your defense means getting thoroughly acquainted with your paper. It might seem like a ridiculous piece of advice if you’ve written it yourself, yet, with a paper of that size, it’s easy to get lost. If you’ve used a dissertation writing service , you need to take special care in learning the contents of your paper. 

Prepare a presentation that you will be showing to the committee. Make sure the slides are clear and easy to understand, with most information placed in the speaker notes. You don’t want to overload the slides with text. 

Analyze your dissertation and think of all the possible questions the defense board members may have afterward. It’s hard to anticipate what a professional may ask about your ‘rookie’ paper, so it might help to speak to your academic advisor before the PhD defense . They might shed some light on the inconsistencies and possible lack of analysis in some areas. 

How to prepare for defense day?

When the day of defending dissertation finally comes, no matter how prepared you are, it will still be stressful. So, it makes sense to come over-prepared. Learn your dissertation text by hard.

Find every grammatical mistake and fix it. Get acquainted with every letter and word and really make sure it’s perfect. If you are convinced your paper is perfect, it will be hard for the defense board to convince you otherwise. 

How do I know I’m ready for my PhD dissertation defense?

Your academic advisor is your best friend in this situation. They have lots of experience in the matter, and they will be the first person to tell you if your paper is defense-proof. If you see them doubting or if they are asking lots of questions, use those questions as learning points. 

Most likely, they criticize you not because they hate you. But because they want to show you your gaps in knowledge. This is a powerful tool to help you find blank spots and fill them

What should I bring to my PhD thesis defense?

  • Presentation Materials : This includes any slides or visual aids you'll use to support your talk. Ensure they are ready and compatible with the equipment available.
  • Laser Pointer : Useful for highlighting specific areas or data on your slides during the presentation.
  • Copy of Your Dissertation : Have at least one printed copy for your own reference. It's helpful for addressing specific questions or sections during the Q&A.
  • Pen or Pencil : For making quick notes or annotations based on feedback or questions you may receive.
  • Notepad : To jot down notes, questions, or reminders during the defense.
  • Bottle of Water : Keeping hydrated is important, especially since you'll be speaking for an extended period.
  • Backup of Your Presentation : Have a backup on a USB drive or accessible online in case of technical difficulties.
  • Any Necessary Forms : Sometimes, there are forms that committee members need to sign post-defense. Check with your department for any such requirements.
  • Questions for Your Committee : Have a list of questions or clarifications you might want to ask your committee after your defense.
  • A Watch or Timer : To keep track of your presentation time and ensure you cover all points within the allotted duration.

Depending on how long is a PhD defense, you will need a different supply. If you are planning to sit through your whole class’ defense, you will need lots of water, some snacks to eat during the breaks, and your presentation materials.

However, if you are allowed to only show up to your defense and not listen to the entire class defend their dissertations, the most important thing you need to have is your dissertation and presentation. And don’t forget to bring some water, it can help you calm down if you get stressed.

Why does the dissertation length vary?

Various elements, such as institutional standards, the research's complexity, the extent of analysis, and the presence of supplementary materials, can determine a dissertation's length.

The length of your defense may also depend on how long is a dissertation . If your dissertation is 70 pages, your defense will definitely run shorter than if it is 300 pages long. The length of your paper will also influence the length of your PowerPoint presentation and the number of questions you get.

But how do you defend a dissertation? Defense is just an academic word for presenting your findings. You do your research, you present it to the board, and they ask you questions. By answering these questions, you defend the legitimacy and academic value of your doctoral defense research.

The key here is preparedness. Being well-acquainted with the contents of your paper and being able to defend it is your key to success. If you’re not sure about some parts of your dissertation, consult your academic advisor. They will be willing to help and advise you on whether you should take another semester to prepare.

Of course, it’s a great thing that ‘ write my dissertation ’ services exist. You can address a service like Studyfy and rely on it completely in the dissertation writing process. If you do, you can order your dissertation chapter by chapter and bring each draft to the professor for their notes and critiques.

What else do I need to know?

The most important part is you need to be prepared to defend dissertation meaning, and you need to know your dissertation by heart and be ready to justify every word in it. Sure, it may sound terrifying but thinking that millions of people have done that before you might give you some ease. 

How long is a dissertation defense?

Normally, defending my dissertation shouldn’t take more than an hour and a half. It usually lasts anywhere between 30 minutes and 1,5 hours.

It depends on your academic level, the number of people defending, and your preparedness. If the committee members sense you’re ill-prepared, they will ask you more questions.

It’s not because they want to thank you, but actually because they want to give you more chances. Asking more questions is usually an attempt to find an area that you’re very good at to give you a chance to redeem yourself.Your doctoral defense ia an important part of your doctoral journey, and it's bound to be more intense than a bachelor’s one. That’s only natural. Since your doctoral dissertation will be more in-depth, show a deeper understanding of the subject and better proficiency. 

The length of your defense will depend on many factors. But the most important one is your preparedness and confidence. If you are not prepared well, the dissertation committee will ask you lots of questions. They do that to find an area of study that you are good at, but at that moment, it might make you even more stressed. So, coming prepared is the best thing you can do for your defense to be successful. 

Using services like Studyfy is also an option. Yet, you must understand that if you show up with a perfectly written paper, yet you have no idea what it’s about, it will raise even more questions. That’s why you must prepare very well, regardless if you write your paper yourself or outsource it. If you still have some questions about how to write a dissertation , make sure to read our guide.

What is the key to dissertation defense?

Comprehensive Preparation: Familiarize yourself with your institution's defense protocols and engage in extensive practice. Segment your thesis for easier presentation, manage timing, highlight essential arguments, and anticipate likely inquiries. Organize a practice defense session to gain comfort with the procedure.

The most important thing you need to do to defend my dissertation is to start your prep early enough. What does it mean to defend your dissertation? Your defense is the pinnacle of all the hard work you've put in your studies throughout the years. Every time you write a paper, you must understand that you may use that research for your dissertation. So, your prep for dissertation defense starts as soon as you enter college.

What is defending a dissertation? Are there dissertation committee members?

Defending dissertation meaning is the process of presenting your research and findings to the board. Regardless if you buy dissertation or write it yourself, you will need to defend it. This is why you need to prepare carefully for your defense - study your paper through and through, think about all the possible questions you may be asked and think of the answers.

The dissertation committee or the dissertation chair are faculty members that will simply ask dissertation defense questions - some about research methodology, and some about the primary role of your work. Before the actual oral defense, try setting up a mock defense with your friend and go over the important topics.

How long is a thesis defense?

It depends on the length of your paper. Since your master’s thesis will probably be a bit shorter than a doctorate dissertation, you can count on your oral defense lasting up to an hour. Again, the length of the doctorate defense depends on how well you are prepared and how you handle the professors’ questions.

Top 7 tips for your defense presentation

1. show why your study is important, remember, your audience is your committee members, researchers in other fields, and even the general public. you want to convince all of them why you deserve a ph.d. degree. you need to talk about why your study is important to the world. in the engineering field, you also need to talk about how your study is useful. try to discuss why current practice is problematic or not good enough, what needs to be solved, and what the potential benefits will be. , see how dr. posen and dr. malings explained the importance of their studies..

2. Emphasize YOUR contribution 

Having a ph.d. means that you have made some novel contributions to the grand field. this is about you and your research. you need to keep emphasizing your contributions throughout your presentation. after talking about what needs to be solved, try to focus on emphasizing the novelty of your work. what problems can be solved using your research outcomes what breakthroughs have you made to the field why are your methods and outcomes outstanding you need to incorporate answers to these questions in your presentation. , be clear what your contributions are in the introduction section; separate what was done by others and what was done by you. , 3. connect your projects into a whole piece of work, you might have been doing multiple projects that are not strongly connected. to figure out how to connect them into a whole piece, use visualizations such as flow charts to convince your audience. the two slides below are two examples. in the first slide, which was presented in the introduction section, the presenter used a flow diagram to show the connection between the three projects. in the second slide, the presenter used key figures and a unique color for each project to show the connection..

4. Tell a good story 

The committee members do not necessarily have the same background knowledge as you. plus, there could be researchers from other fields and even the general public in the room. you want to make sure all of your audience can understand as much as possible. focus on the big picture rather than technical details; make sure you use simple language to explain your methods and results. your committee has read your dissertation before your defense, but others have not. , dr. cook and dr. velibeyoglu did a good job explaining their research to everyone. the introduction sessions in their presentations are well designed for this purpose. .

  • Irem Velibeyoglu Defense with Notes

5. Transition, transition, transition

Use transition slides to connect projects , it's a long presentation with different research projects. you want to use some sort of transition to remind your audience what you have been talking about and what is next. you may use a slide that is designed for this purpose throughout your presentation. , below are two examples. these slides were presented after the introduction section. the presenters used the same slides and highlighted the items for project one to indicate that they were moving on to the first project. throughout the presentation, they used these slides and highlighted different sections to indicate how these projects fit into the whole dissertation. .

You can also use some other indications on your slides, but remember not to make your slides too busy.  Below are two examples. In the first example, the presenter used chapter numbers to indicate what he was talking about. In the second example, the presenter used a progress bar with keywords for each chapter as the indicator.

Use transition sentences to connect slides 

Remember transition sentences are also important; use them to summarize what you have said and tell your audience what they will expect next. if you keep forgetting the transition sentence, write a note on your presentation. you can either write down a full sentence of what you want to say or some keywords., 6. be brief, put details in backup slides , you won't have time to explain all of the details. if your defense presentation is scheduled for 45 minutes, you can only spend around 10 minutes for each project - that's shorter than a normal research conference presentation focus on the big picture and leave details behind. you can put the details in your backup slides, so you might find them useful when your committee (and other members of the audience) ask questions regarding these details., 7. show your presentation to your advisor and colleagues, make sure to ask your advisor(s) for their comments. they might have a different view on what should be emphasized and what should be elaborated. , you also want to practice at least once in front of your colleagues. they can be your lab mates, people who work in your research group, and/or your friends. they do not have to be experts in your field. ask them to give you some feedback - their comments can be extremely helpful to improve your presentation. , below are some other tips and resources to design your defense presentation. .

Definition: Thesis Defense

A thesis defense is an act of presenting your work to a panel of professors so they can grade your presentation abilities. In retrospect, the argument is essential to ascertain that you understood the topic. You have to hand in your paper first so that the lecturer can grade it before you appear for the defense.

As a university student, you need to hand in a high-quality thesis paper and defend it before a panel of professors. So what is this that takes place during a thesis defense? Read along to find out.

In a Nutshell

So, there you have it. These tips should help you present your thesis defense and ace it. Remember that:

  • You should present facts that are in the paper. Do not add any new information
  • Make the thesis defense as enjoyable as possible
  • Arrive early enough
  • Do not exceed your allocated time
  • Confidence goes a long way

Before the Thesis Defense

Before the day of the thesis defense, the qualifying students receive a timetable that shows the chronology of how the day will be. You are required to keep time, or else you will have to wait until the next allocated defense to present your paper. To qualify as a defending student, you have to hand in your paper at least one month before the thesis defense date.

What happens in a Thesis Defense?

Once you get to the hall, you need to introduce yourself and your topic, then present your paper to the lecturers. The professors will allocate you ¾ of the allotted time for the thesis defense. The remaining time is used up in the question and answer forum. Prepare yourself to answer several questions, such as:

  • Your plans after completing the research
  • The limitations you faced
  • Things that you would change if given a chance
  • How you chose your target audience
  • How you intend to further your study on the subject
  • The reasons for choosing your topic
  • The most significant deductions you learned from the survey
  • Reasons for choosing your research methodology, etc.

In some cases, the board may ask you to summarize your deductions from the study. The questions asked are not standard, which means you have to be thoroughly prepared to answer whatever the panel throws your way during the thesis defense. Other things that take place during the thesis defense include:

  • Deliberations – At this point, the board of lecturers will ask you to leave the room as they deliberate on your thesis defense performance. They will then decide whether you move to the next level or you will defend again.
  • Verdict – Finally, the team will invite you back in and tell you how you performed in the thesis defense. These panel members may ask you to make a few corrections before you can go ahead and publish your paper. You have to present your corrections to your facilitator, who will then give you the go-ahead to publish.
  • Signing – The members will then sign your document to ascertain that you were part of the thesis defense team on the selected date.

How much time does a Thesis Defense take and how many people should be in the room?

During a thesis defense, each student appears before the panel individually. The facilitators will ask you questions concerning your topic to see if you fully grasped the concept. Each thesis defense will vary from the other depending on the technicality of your paper and the kind of degree you are pursuing.

  • Undergraduate degree – Your panel may include at least three lecturers from your faculty. Additionally, the defense may last up to one hour.
  • Masters degree – You get to interact with four professors at this level, and each student is allotted 1½ hours to present and answer questions.
  • Ph.D. degree – Considering that this is the highest education level, five professors avail themselves to vet you. More so, you may have to engage them for two hours.

What to include?

A thesis defense follows a particular format, which cuts across all types of degrees, which is:

  • Introduction  – Explain the need for this study
  • Literature review  – Explain what other scholars have found on the subject
  • Research methodology  – What research method did you use, and why did you use it?
  • Findings and discussions  – In your research, what were the key deductions that you came upon?
  • Implications, limitations, suggestions, and  conclusion  – Here, you have to exhaust the setbacks you encountered during the study, the consequences that your target audience will face if they do not follow the deductions, and then finally sum up the discussions.

Tools for Thesis Defense

Considering that a thesis defense may take you at least 45 minutes to present, it is essential to make the presentation lively. So, you can incorporate a slide show and use images to make it less wordy. Bullet points also make the text easier to digest as opposed to a block of text. So, a laptop and a projector will help you ace your presentation.

Thesis Defense Anxiety

Standing before a panel of people waiting to hear how you conducted your research can be intimidating. This is especially so considering that you will be standing before a group of professors, who you believe to be superior to you in regards to the topic knowledge. More so, if you are not familiar with public speaking, it is easy to develop stage fright while defending.

Manage Thesis Defense Anxiety

In case you find yourself fidgeting before you begin presenting, use the following tips to help you get your composure back.

  • If you have a problem with eye-balling the lecturers, look at the tips of their foreheads instead.
  • Take a few seconds to breathe in and out so you can stabilize your speech if you begin to stammer.
  • Go into the room with a positive mind, knowing that you will do your best.
  • Most importantly, rehearse your thesis defense severally before the D-day.

What is a thesis defense?

A scholarly thesis defense is a forum that allows students to present their paper’s contents and defend their thesis topic before a panel of professors. The student is then required to answer all questions asked by the lecturers. At the end, the student is required to leave the room whilst the professors decide whether the thesis is ready to be published, or if it needs corrections.

How long is a thesis defense?

There is no general length for a thesis defense. The defense of a master’s thesis will take longer than the defense of a bachelor’s thesis. You will need to fit in an introduction , a literature review, your findings and even more into the time frame for your thesis defense, so it’s important that you’re well prepared. All in all, it depends on your paper and your academic field. Usually the thesis defense will last between one and two hours, but it also could be less than one hour.

What is the oral defense of a thesis?

Oral defense is simply another name for your thesis defense. If you’ve completed your thesis, you are required to defend it in front of a panel of professors. It is designed so that the committee can ensure that the students completely understand their thesis topic . The oral thesis defense is an examination of a completed body of work. Students will be assigned a date to defend their thesis.

What happens after the thesis defense?

After your thesis defense, you will be told to leave the room whilst the panel discusses your results. There are normally 2 outcomes. You may need to make changes to your thesis’ formatting or content. If this is the case, don’t stress! You’re able to try the thesis defense again once you’ve incorporated any required changes. The preferred outcome is that the panel is happy with your thesis and it’s then ready to be signed and published.

What defines a good thesis defense?

The thesis defense is the final step for your academic work. It’s important that you’re prepared and you’ve outlined what you’re going to say in each section of the defense. You need to know your thesis statement better than the back of your hand, otherwise you risk being sidetracked. Just like your thesis itself, your thesis defense has a specific structure. You can read more about this further on in the article. Try and prepare yourself for the potential types of questions that the professors will ask you so that you don’t have to think about your answers on the spot.

What to expect in a thesis defense.

A thesis defense is your chance to demonstrate your in-depth knowledge and expertise in the topic of your research thesis. While you will be able to take charge of the narrative and present your research to those on your thesis committee, the professors will prod you to test how well you know and understand your topic. The questions are mostly open-ended and give you the chance to showcase your knowledge and understanding, as well as any future plans you may have regarding your research topic.

A thesis defense usually lasts between one and two hours, depending on the area of your research. It starts with you giving a presentation of your interest, findings, and conclusions. After you have finished, the committee members will ask you questions based not only on your presentation, but also on your written thesis as they will have read it before your presentation. Lastly, the committee might approve your thesis or suggest changes to your paper.

Preparing thesis defense questions requires you to start well in advance. While the duration of your thesis defense might vary as per your institution's requirements, the major idea is to defend your research. Thus, you should go about preparing for your thesis defense questions by taking the following steps.

Interested in a quick overview of the section below? Check out this infographic:

Re-read your thesis for clarity

Your thesis defense questions will be based on what you have written in your research paper. Hence, it is a good idea to re-read your paper. You should be clear on the concepts and understand your research well. It might have been some time since you would have submitted your paper, so a revision should be the starting point of your preparation.  

Have an answer strategy and structure

Plan a strategy to answer the panel’s questions. Keep your answers direct, but elaborate on the research details wherever necessary. If you do not know the answer to a question, that is alright. The key is to be able to formulate an answer even if you do not possess enough knowledge to answer at that point in time. For instance, if a question is about the content of your research, you can say something like “I am not certain my research touches on the question you are asking, but my research has led me to Dr. X. Based his evidence, I would have to conclude that…” Having a strategy for answering even the most unexpected questions can be a life saver in these situations!

Most of the thesis defense questions can be easily predicted based on your research. You can prepare a list of possible questions when you are going through your paper. Getting to know the committee can help you in preparing better. Their areas of expertise can help you in determining what they might ask. Once you have a list of questions, you can start brainstorming how you might answer them. 

Prepare your slides in advance

If you require visual aids such as slides, it is a good idea to prepare them beforehand. You can double-check the slides and make sure that your presentation will run smoothly on the day of your thesis defense. Make sure your slides are arranged in the correct order. 

Attend a thesis defense of other candidates if it is an open event

If your institution allows it, you can visit a thesis defense of other candidates. This will give you an excellent idea of what you can expect in your meeting. If it is not possible to attend the event, you can speak to your peers to find out how their meeting went and what questions were asked.

Dress appropriately for your meeting

The thesis defense meeting is a formal event, and hence you should be dressed in formal clothes. While there are no strict dressing rules, you should consider it something equivalent to a job interview. Don’t just wear your T-shirt and appear in front of the committee. Your formal suit is a better option for the occasion.

Practice speaking for your meeting

Take your preparation to the next level by practicing your presentation. This activity will give you the confidence for the actual meeting and presentation. You can request your academic peers to help you out in the practice task. Based on their feedback in the mock session, you can improve for the actual session. Make sure to prepare well for the mock session as if you are preparing for the actual session. You can also practice your speech and body language in the mock session. If you used thesis writing services , these professionals would also be the ideal people to test you in a mock thesis defense – don’t hesitate to reach out to them again!

Sample Thesis Defense Questions and Answers

1.    what is your research study all about.

In your answer, you should summarize your research in a few sentences. The question is simple but requires technical expertise for a better explanation of concepts. For instance, if you completed a thesis in an attempt to explain the constituents of dark matter in the universe and particle accelerators, you could frame your answer like this:

In this research, the different aspects of dark matter and its detection models have been investigated. The cosmic ray positron excess observed by the PAMELA detector has been discussed and explained through the construction of models of decaying dark matter. The cosmic-ray electron and positron spectra were studied assuming a general Dirac structure for the four fermion contact interactions of interest. A supersymmetric leptophilic Higgs model was constructed to explain the possible excess of gamma rays in the galactic center. Finally, by the use of Razor analysis, an improvement on the dark matter collider searches is considered.  

2.    Why did you choose this study?

This question requires you to answer what motivated you to pursue the study in the first place. Your answers could touch on your interests in the area of the study. For example, if you conducted a study called “Media Combat: The Great War and the Transformation of American Culture” then you can shape your answer like this:

The First World War (1914-1918) has always been a topic of fascination for me, and my prime interest lies in exploring the state of society at that time. I wanted to analyze the formation of a nationalized, wartime cultural apparatus during the United States' involvement in the war and how theatre and music transformed the relationship between the government and American citizens. 

3.    Why did you choose this particular title for your research?

The title of your thesis captures the main point of your research, which is why it is so important to use an appropriate title. Your committee will want to know how you came to the final decision of naming your work. For example,

I chose the title “Dark matter in the heavens and at colliders: Models and constraints” for my research thesis because my research attempts to explain the constituency of dark matter as it occurs in the universe. “The heavens” is another word for the universe. Dark matter can also be created in particle accelerators such as the CERN collider. I have attempted to provide an explanation for both of the cases through the use of models, along with describing the constraints which exist in the current times due to certain scientific limitations.

4.    What is the scope of your study?

In your answer, you have to define the boundaries of your project and define exactly what you are studying. There can be several elements involved but you have to define the parameters that you have chosen to study. For example,

My study is on the efficacy of equity stocks in the US market. For my study, I have chosen 50 companies listed on the NASDAQ. You can review the names of these companies on page 5 of my thesis.

5.    What phenomenon were you trying to understand with this research?

Describe the focus concept of your thesis in the answer. For example,

In our study “Motivation to volunteer”, we were looking to study the Theory of Planned Behavior by analyzing the behavioral and normative beliefs that influence attitudes and subjective norms.

Want increase your productivity and mainain a healthy work life balance to help get you through your thesis project? Here are some tips straight from our CEO:

6.    Who will be most interested in your research?

You can talk about who may be affected by your research and the parties who can potentially benefit from the research. Take a look at this example:

My sociology thesis on “Impact of social media on youngsters” can be of interest to sociology academics, social media companies, education experts, and parents of youngsters in general.

7.    Did your research questions evolve during the process? If so, how?

Often, qualitative research questions change over time with respect to the responses that you might get from your focus group. Or you might just change your question as you do lab research or general text research. You can describe the change to the evaluating committee. For example,

We started our study to understand the impact of the new public policy change on recycling of vinyl waste through installation of garbage bins specifically for vinyl products. However, after interviewing some of the respondents in the target community, we found that the rule is actually irrelevant to their behavior and thoughts because the percentage of vinyl waste in that specific locality was very low and it didn’t need the installation of dedicated bins for the purpose. Going by their frustrations with the current economic insecurity, our study evolved into the impact of costs incurred by public policy changes.           

8.    What gaps did you intend to bridge with your research?

Your research thesis must eliminate the present gaps in the concepts related to your subject topic.

The relationship between hard water and its effect on the size of the kidney stone is not clear yet, so we analyzed the mineral composition of hard water to determine its impact on the size of the kidney stone.

9.    Why is your research significant?

The answer to this research question should outline the impact of your research on your field of study. You may talk about the new insights contributed by your research and its impact on society.

Through my study on “The effect of chamomile in reducing stress and promoting better sleep,” patients with insomnia and anxiety will be able to find alternative treatments without the use of medicinal drugs. The medical abilities of chamomile will promote the usage of ingredients in nature and will encourage the community to plant more herbs and trees.

10. What did you find in your research?

You may describe your research in a few sentences in this answer. For instance,

In our study on “Impact of artificial fluoride in water on the human body,” we found that excessive exposure to high quantities of Fluoride can result in tooth discoloration and bone issues in humans since it has neurotoxic qualities. 

11. What research findings surprised you?

When you conduct research, you come across findings that you were not expecting earlier. If you had such an experience, you might describe the same to the evaluation committee when you answer this question. For example,

I was expecting that business promotion through social media would not be a good idea for rural enterprises in developing countries in my comparative analysis of the usage of traditional and contemporary marketing methods. But I was surprised to learn that 68% of rural textile businesses in Nigeria promote their products on Instagram.

12. What is the validity of your findings?

You have to talk about the conditions in which your research findings would be valid.

In my research, I have considered test anxiety to be involving both nervous system activation and negative thoughts. Thus, my measure of test anxiety has included the elements of both nervous feelings and negative thoughts, the conditions in which my findings are valid.

For example,

For studying the differential protein expression, its localization, and distribution at different levels, we used the method of immunostaining in our research.

14. What sources did you use for data collection?

You would have used several sources to search for data for your topic. You may elaborate on those sources. You might have referred to databases, content on the web, or even conducted primary research by interviewing prospects. Thus, you can talk about these sources. Refer to the following answer:

To understand the impact of the current tax regime on skilled workers, we interviewed 150 subjects in 5 months. Additionally, we referred to databases and scholarly works available by authors who had previously conducted such studies for previous tax laws and rates. 

15. How can your research be put into practice?

This question talks about the practical implications of your research. You should talk about how your research is beneficial for society and how it can help in eliminating current issues.

In our research titled “Effectiveness of Meditation on Reducing the Anxiety Levels of College Students in the US,” we discovered that students who practiced meditation at least thrice a week were two times more likely to score better in their exams, owing to the positive impact of meditation. So, this research finding can help in the reduction of mental health issues among students. A suitable course of action would be to hold meditating sessions a couple of times a week. 

16. How will your findings contribute to the related area of knowledge?

Our study on medicinal analysis of herbs conveys information about various medicinal benefits of chamomile in treating depression and contributes to the area of medicinal botany.

17. Did you experience any limitations in your research?

Our research on “Impact of smoking on β-cell function and risk for type 2 diabetes in US citizens” finds that smoking increases the risk of diabetes among smokers. However, smokers might be affected by some genetic conditions which can protect them from diabetes. 

18. What sampling techniques did you use?

When conducting research, it is practically not possible to study the entire number of elements. So, you would be using a method to select a sample population.

In our study “Impact of consumption of soda on the health of teenagers in Corpus Christi”, we used area sampling to divide the city into several areas and then selected some clusters for our sample group.

19. What are the dependent and independent variables in your research?

In research, several variable factors impact your study. You can describe these variables. Independent variables have values which are not affected by other variables in your study. On the other hand, the dependent variables have values that change with changes in the independent variable. For example,

In our study on “Impact of online tutoring on test scores”, the independent variable is the nature of the classes i.e., online and the participants' test score is the dependent variable.

20. What areas do you suggest for further research?

As a researcher, you should be able to describe what further areas are open for research with the addition of your research to the field. This can act as a starting point for future researchers. For example,

In my research on “Effectiveness of Acetaminophen in treating sports induced injuries”, I discovered that administering Acetaminophen is not very effective for treating joint pains such as the knee. This further suggests measures for the regulation of Acetaminophen in the production of painkillers for body pain and the search for alternative compounds.

Practice Questions

After taking a look at the sample answers, now try answering these questions by yourself:

Do you have any closing comments? "}]">

After submitting your research thesis for evaluation, you have to appear before a panel of professors and present your work; afterwards, they will ask you questions about your research.

You have to plan and prepare for your thesis defense. Review your paper and anticipate the questions that the committee can ask. Practice with mock defense sessions using professional servicesand make improvements based on their feedback. Be prepared with a strategy for answering any question asked by the panel.

Your research thesis should be on a topic of your interest. Scan your course syllabus to find something that makes you curious. Or, you can even refer to your grad school career goals statement to review what got you interested in grad school in the first place. Shortlist a few topics and zero down to the one that excites you the most.

The first step in preparing for a master’s thesis defense is to revise your research paper and write down a list of questions that the committee might ask. Find answers to those questions and get ready for your presentation. Practice your presentation beforehand. Try to attend a thesis defense of other candidates to know what you can expect in your session. 

You will get questions related to what you have mentioned in your research paper. The most common starting questions are “what is your research about?" and “what was your motivation behind choosing this topic?” Later on, the committee asks you more detailed questions on research methodology, literature review, study variables, research findings, recommendations, and areas of further research.

You can get help from a grad school essay tutor for your research thesis writing. They can help you in developing writing skills and reviewing your work. They can proofread your work and provide recommendations on areas of improvement.

You can include your research thesis on your grad school CV to show your practical knowledge and skills. You can add the details of the study in a separate section for research experience.

Immediately after the thesis defense, the evaluation panel will decide whether to approve your paper as submitted or request some changes, or reject it.

To pass a thesis defense, a majority of the panel members must approve the defense. In case of more than one vote against you, you can fail the thesis.

A thesis defense can last for two hours or longer, depending on your area of research.

Your thesis defense presentation should include the focus concept, findings, recommendation, and conclusion.

The contribution of your thesis towards your degree differs as per institution. You can refer to your course handbook for exact details. In most cases, the committee needs to approve your thesis for you to graduate from your degree.

Graduate School

Oral Defenses of Theses and Dissertations

Master’s students completing a thesis and doctoral students completing a dissertation are required to engage in a final oral defense of the document by their thesis or dissertation committee. 

Information on defense policies and procedures is available in the PSU Bulletin: Please review the thesis section for details about thesis defenses. Please review the dissertation defense section for details about dissertation defenses.

Preparation in advance of the defense

  • The thesis or dissertation committee must be approved by the Graduate School via a GO-16 prior to  holding a thesis or dissertation defense.  
  • Students must be registered for at least 1 graduate credit in the term of the defense.  
  • Defenses should be held during regular academic terms, i.e., not between terms. However, if there is a need to hold a thesis/dissertation proposal or final defense in the period between terms, and all faculty involved in the defense have agreed to participate at this time, graduate programs are allowed to schedule defenses between terms provided certain requirements are met. See Enrollment for Defenses/Exams Held Between Terms for details.   
  • Defenses may be held in-person, remotely via videoconferencing (e.g., Zoom), or in a hybrid format with both remote and in-person participation. Please review the Remote Thesis/Dissertation Participation guidelines for defenses in which the student or at least one committee member is participating remotely.   
  • Thesis  defenses are open to the University faculty and may be open to the public at the department’s discretion. Dissertation defenses are open to the public. Students should check with their department for internal policies regarding scheduling and announcing thesis and dissertation defenses.

The defense

  • All appointed committee members must participate in the defense, even if the committee has more than the minimum required members. Refer to the approved GO-16 or DARS audit to confirm committee membership or contact Graduate Academic Services at [email protected] . Any changes to committee membership must be made in advance of the defense. 
  • The student should not be expected to provide food or beverage for attendees of the defense. 
  • If a committee member is missing at the start of a defense, the student and committee must wait at least 15 minutes for them to join the meeting. In the meantime, the committee chair should contact the Graduate School at (503) 725-8410 for options in case the member cannot be located. 

Structure of the final defense

The master’s or doctoral candidate is expected to prepare and give an oral presentation on the research methodology and results. After the student’s presentation, they will defend the thesis or dissertation in a question and discussion session. 

  • The student's oral presentation should not exceed 60 minutes.
  • Defenses should be scheduled for 2 to 3 hours to allow enough time to accommodate all steps of the defense and a robust questioning and discussion session. Appointed committee members must participate in all the steps of the defense. The actual length of the defense will depend on how long each step takes.

Example structure of a defense:

  • Allow 10-15 minutes for attendees to arrive. Allow at least 15 minutes for all committee members to arrive.
  • Committee chair makes introductions and directs the defense meeting. 
  • Student presents for 30-40 minutes. (Individual programs may have specific requirements about presentation length.)
  • Questioning and discussion session. This session may be held publicly with all attendees and/or privately with only the student and the committee. (Depending on departmental practice, there may be both a public and private questioning and discussion session.)
  • Allow 10 minutes for the student and everyone except the committee members to leave the room. 
  • Committee members deliberate and discuss the result of the defense. Each committee member votes on the defense. (Votes will be captured via the GO-17 form.)
  • Student is called back to the room to receive the result of the defense and any revisions required by the committee in order to give final approval to the thesis or dissertation. 

Defense and Dissertation Overview

Once a student’s box is checked, the BPH student should set up a one-on-one “Defense Packet Meeting” with the BPH Associate Director to review the Defense and Dissertation Process, which includes reviewing all required materials, logistics, timing, FAS/Harvard Griffin GSAS Form of the Dissertation, sample forms, and to answer student questions related to these processes.

thesis defense length

  • Defense Committee Chair: One member of the student’s DAC, often the DAC chair, is required to chair the oral defense. This required holdover from the DAC serves the purpose of providing insight to the examiners regarding the path the student has taken in completing the dissertation research. Their primary role is to assess committee satisfaction with the written dissertation, administer the exam, arbitrate any problems that may arise, and make final recommendations for completion of necessary corrections and additions to the dissertation. No other DAC members can serve on the defense committee .
  • At least one member must be a BPH faculty member, often from the same academic department.
  • One member of the examination committee must be from outside of Harvard University.
  • The fourth member may be from either BPH or another Harvard-affiliated program.
  • Co-authors and collaborators cannot be members of the Defense committee
DEFENSE TIMING AND FORMAT
  • Students should notify the BPH Program as far in advance as possible with the details of the exam. 
  • The student is required to notify the BPH office no later than 3 weeks in advance of the defense with the final dissertation title.
  • At least two weeks before the date of exam, defense members should be sent copies of the dissertation for review. A copy of the dissertation should also be sent to the BPH program.
  • If any defense committee member foresees problems with the exam, they should contact the chair of the defense committee in advance of the meeting. If major problems are found with the written document, the Committee can decide to postpone the oral defense until satisfactory changes are made. While rare in our program, these occasions can involve the insufficient or improper use of statistical methods, grossly overstated conclusions, insufficient background or discussion, or evidence of plagiarism.
  • More details about the timing and format are provided in the “Defense Packet Meeting” held with each student.

STIPEND GUIDELINES

If a student successfully defends the dissertation before the 15th of the month, the stipend will be terminated at the end of that month. If the student successfully defends on or after the 15th, the next month’s stipend will be the final month the student is paid, at the discretion of their advisor.

Students are encouraged to speak to their advisors directly about how they should be paid as they complete their graduate work. If an advisor wishes to pay the student for one additional month, beyond what has been explained above, the advisor must notify the department’s financial administrator. For administrative reasons, a stipend cannot be issued to a student after their graduation/degree conferral date.

ORAL DEFENSE PROCEDURES

Part 1: Public Seminar As part of the exam, the PhD candidate will present a public seminar followed by a private oral examination.  The public presentation lasts no longer than 1 hour, which includes time for the advisor’s introduction, the student’s oral presentation and acknowledgements, and time for audience questions and answers.  The Defense Committee is required to attend the public seminar; however, it is customary for members of the defense committee to hold their questions until the private oral exam.

Part 2: Private Oral Examination A private oral examination follows the public seminar.  Initially, the student will be asked to leave the room for several minutes, along with the dissertation advisor if the dissertation advisor has decided to remain for the private exam.  During this time, the committee will discuss the merits of the dissertation, any issues with the dissertation, and areas they may want to focus on during the oral exam.  The student (and advisor if present) is then asked back into the room for the exam.

Each member of the defense committee will direct questions to the candidate based on their review of the dissertation and presentation of the seminar. The Defense Chair will moderate the discussion between the panel and the student.  The closed defense takes up to two hours and involves detailed technical questions as well as broader questions on the conclusions, impact, and limitations of the research.  Dissertation advisors may be present, but they must not participate in the exam (e.g., answer questions posed by the committee).

At the end of the examination, the student (and advisor if present) is once again asked to step out of the room for several minutes.  The Committee will discuss any revisions needed for the thesis and whether these revisions need to be reviewed and by whom.  Once the committee determines the outcomes, the student will be asked back into the room and the Committee provides the student with any [minor] changes needed to the dissertation. While it is extremely rare for the student to fail at this stage, the committee will provide recommendations to the student on their research, communication skills, and development as a scientist, as well as delineating the required changes to the dissertation.

PREPARING FOR THE DEFENSE/WRITING THE DISSERTATION

Students preparing to write and defend their dissertation must review University requirements as outlined in “ Dissertations ” with guidelines published at the Graduate School of Arts and Sciences.

Students are also welcome to visit the BPH Student Lounge (Building 2, Room 113) to look at copies of previous BPH bound dissertations.

Writing the Dissertation Each student must write a comprehensive PhD dissertation on their research topic and the original results of their research. There are a variety of ways a dissertation can be composed, but the core elements described below must be included. The dissertation must show original treatment of the subject, contain a scholarly review of the pertinent literature, provide evidence of independent research of publishable quality, and be clearly, logically, and carefully written. In addition to a compendium of the student’s research, including detailed methods and results, the dissertation must contain a thoughtful discussion of the conclusions, impact, and limitations of the research. The completed work should be critically reviewed by the dissertation advisor before being submitted to the Dissertation Defense Committee.

In some cases, the student has done all of the work in the dissertation; more often portions of the dissertation result from collaborative research. In all dissertations containing collaborative results, the dissertation should indicate concisely who contributed to the work and how.  For example, a chapter containing multi-authored, published work must include a complete reference of the publication and a brief description of the candidate’s and the colleagues’ contributions. For work that is not published but which resulted from multiple researchers, the contributors must be named and respective attributions made clear. This policy allows stylistic flexibility; depending on the amount of collaborative work in the dissertation and the status of publication(s), the attributions can be, preferably, on or accompanying the cover page for each chapter or within an extended acknowledgements section at the end of each chapter. It is recommended that if figures or figure panels are included that are the work of others that the figure panels be clearly identified and the work properly attributed. It is permissible for more than one student to include work from the same collaboration or publication as long as the required attributions are clear, justified, and complete.

Individual chapters can be that of published articles as long as there are also comprehensive Introduction and Conclusion chapters written by the student. While the text can be the same, use of journal reprints as a chapter is not permissible. A word document of the published article must be used, and the pages in the dissertation must be consecutively numbered. Furthermore, the figures and accompanying figure legends must be integrated into the main body of each chapter, preferably following the first mention of the given figure, not clustered at the end of the chapter. Any dissertation that varies significantly from the Graduate School or FAS guidelines, or is not neat and readable, is subject to required stylistic revision before acceptance by the University. (For further information, please visit https://gsas.harvard.edu/academics/dissertations ).

DEFENSE FORMS AND PAPERWORK

Dissertation Acceptance Certificate Before the examination, the BPH Program Office will provide the Defense Committee Chair with a copy of the official Dissertation Acceptance Certificate. This certificate must be signed by all readers of the dissertation at the end of the examination and returned to the BPH Program Office. This certificate will be scanned and sent to the student so it can be inserted as page one of the dissertation prior to the online submission. The student must submit the one original, official copy to the Registrar’s in Cambridge by the appropriate deadline.

If extensive corrections are to be made, the BPH Program Office will hold the certificate until the Defense Committee Chair, and/or assigned reviewer(s) provide a written notification to the BPH Program to confirm that the corrected work has been reviewed and approved.

Dissertation Defense Exam Report The Dissertation Defense Exam Report is completed by the members of the Dissertation Defense Committee to provide a record of any comments or recommendations they may have. The report must be signed by all members immediately after the private exam. The completed report must be submitted to the BPH Program Office at the same time as the Dissertation Acceptance Certificate.

  • How Long Is a PhD Thesis?
  • Doing a PhD

It’s no secret that one of the most challenging aspects of a PhD degree is the volume of work that goes into writing your thesis . So this raises the question, exactly how long is a thesis?

Unfortunately, there’s no one size fits all answer to this question. However, from the analysis of over 100 PhD theses, the average thesis length is between 80,000 and 100,000 words. A further analysis of 1000 PhD thesis shows the average number of pages to be 204 . In reality, the actual word count for each PhD thesis will depend on the specific subject and the university it is being hosted by. This is because universities set their own word length requirements, with most found to be opting for around 100,000.

To find out more about how these word limits differ between universities, how the average word count from STEM thesis differ from non-STEM thesis and a more detailed breakdown from the analysis of over 1000 PhDs, carry on reading the below.

Word Count Differences Between Universities

For any PhD student writing a thesis, they will find that their document will be subject to a word limit set by their university. In nearly all cases, the limit only concerns the maximum number of words and doesn’t place any restrictions on the minimum word limit. The reason for this is that the student will be expected to write their thesis with the aim of clearly explaining their research, and so it is up to the student to determine what he deems appropriate.

Saying this, it is well accepted amongst PhD students and supervisors that the absence of a lower limit doesn’t suggest that a thesis can be ‘light’. Your thesis will focus on several years worth of original research and explore new ideas, theories or concepts. Besides this, your thesis will need to cover a wide range of topics such as your literature review, research methodology, results and conclusion. Therefore, your examiners will expect the length of your thesis to be proportional to convey all this information to a sufficient level.

Selecting a handful of universities at random, they state the following thesis word limits on their website:

  • University of Edinburgh: 100,000
  • University of Exeter: 100,000
  • University of Leister: 80,000
  • University of Bath: 80,000
  • University of Warwick: 70,000

The above universities set upper word limits that apply across the board, however, some universities, such as the University of Birmingham and the University of Sheffield, set different word limits for different departments. For example, the University of Sheffield adopts these limits:

  • Arts & Humanities: 75,000
  • Medicine, Dentistry & Health: 75,000
  • Science: 80,000
  • Social Sciences: 75,000-100,000

Although there’s a range of limit, it’s safe to say that the majority fall within the 80,000 to 100,000 bracket.

Word Count Based on Data from past Theses

A poll of 149 postdocs.

In mid-2019, Dr Eva Lantsoght, a published author, academic blogger and Structural Engineering Professor, conducted a poll which asked postgraduate doctoral students to share the length of their final thesis. 149 PostDoc students responded to the survey, with the majority reporting a length falling within the ‘80,000 – 120,000 words’ bracket as seen below.

DiscoverPhDs_How-long-is-a-PhD-Thesis_Poll

Analysis of 1000 PhD Theses

Over a three-year time period, Dr Ian Brailsford, a then Postgraduate Learning Adviser at the University of Auckland, analysed 1000 doctoral thesis submitted to his university’s library. The PhD theses which formed the basis of his analysis were produced between 2008 to 2017 and showed:

  • Average number of pages = 204
  • Median number of pages = 198
  • Average number of chapters = 7.6

We should note that the above metrics only cover the content falling within the main body of the thesis. This includes the introduction, literature review, methods section, results chapter, discussions and conclusions. All other sections, such as the title page, abstract, table of contents, acknowledgements, bibliography and appendices were omitted from the count.

Although it’s impossible to draw the exact word count from the number of pages alone, by using the universities recommended format of 12pt Times New Roman and 1.5 lines spacing, and assuming 10% of the main body are figures and footnotes, this equates to an average main body of 52,000 words.

STEM vs Non-STEM

As part of Dr Ian Brailsford’s analysis, he also compared the length of STEM doctorate theses to non-STEM theses. He found that STEM theses tended to be shorter. In fact, he found STEM theses to have a medium page length of 159 whilst non-STEM theses had a medium of around 223 pages. This is a 40% increase in average length!

Can You Exceed the Word Count?

Whilst most universities will allow you to go over the word count if you need to, it comes with the caveat that you must have a very strong reason for needing to do so. Besides this, your supervisor will also need to support your request. This is to acknowledge that they have reviewed your situation and agree that exceeding the word limit will be absolutely necessary to avoid detriment unnecessary detriment to your work.

This means that whilst it is possible to submit a thesis over 100,000 words or more, it’s unlikely that your research project will need to.

How Does This Compare to a Masters Dissertation?

The average Masters dissertation length is approximately 20,000 words whilst a thesis is 4 to 5 times this length at approximately 80,000 – 100,000.

The key reason for this difference is because of the level of knowledge they convey. A Master’s dissertation focuses on concluding from existing knowledge whilst a PhD thesis focuses on drawing a conclusion from new knowledge. As a result, the thesis is significantly longer as the new knowledge needs to be well documented so it can be verified, disseminated and used to shape future research.

Finding a PhD has never been this easy – search for a PhD by keyword, location or academic area of interest.

Dissertation Defenses

As part of the degree requirements for a Ph.D. in computer science or computer engineering, students must pass a final examination given by their advisory committee as described in the graduate catalog. The part of the exam that is related to the presentation of the student's research is public (the dissertation defense).  The final examination may not be administered before the dissertation is available to all members of the student's advisory committee in substantially final form, and all members have had adequate time to review the document. Final corrected copies of the dissertation must be accepted by the thesis clerk no later than one year after the final examination or within the 10-year time limit, whichever occurs first. Failure to do so will result in the degree not being awarded.

Listed below are the major steps that should be completed for Ph.D. dissertation defenses in the Department of Computer Science and Engineering at Texas A&M University. Much of this information is taken from the  graduate catalog ,  Steps to Fulfill Doctoral Degree Requirements  page on the Graduate and Professional School website  and the department's graduate brochure.

Requirements

Final exam deadlines are listed on the  Graduate and Professional School calendar  (usually about eight weeks before graduation).

To be eligible to schedule the final examination, the student must meet the following requirements:

  • An approved dissertation proposal must have been submitted to the Graduate and Profesional School at least 15 days before the request to hold the final examination (dissertation defense) is submitted to the Graduate and Profesional School (or about four weeks before the defense). (This is a decrease - it used to be 14 weeks before the defense.)
  • All course work on the degree plan must be completed with the exception of any remaining CPSC 691 (Research) hours and the student must be registered for those hours. This means all petitions to change the courses on the degree plan must be filed and approved before the exam can be scheduled.
  • The cumulative and degree plan grade point ratios must both be at least 3.00. There cannot be any unabsolved grades of D, F, or U for any course listed on the degree plan. To absolve a deficient grade, the student must have repeated the course at Texas A&M and have achieved a grade of C or better.
  • All English proficiency requirements must be satisfied prior to scheduling the examination.
  • Students must be registered in the university in the semester or summer term in which the final examination is taken.

Listed below are the steps that should be followed in scheduling and administering final examinations (dissertation defenses) for Ph.D. degrees in the Department of Computer Science and Engineering.

  • The student and the chair of the advisory committee should review the eligibility requirements for the final exam and ensure that the student has satisfied them all. If different courses were taken than are listed on the degree plan, then the appropriate petitions should be filed to make the necessary changes; all such petitions must be approved by the Graduate and Profesional School before the exam can be scheduled. Deadline: several weeks before exam.
  • The student should consult with their advisory committee and select a mutually agreeable date and time for the defense. All advisory committee members should attend the final examination. If one of the members cannot attend the examination, he or she must find an appropriate substitute. The committee chair may not be substituted. (Note that the committee member and not the substitute should sign the dissertation approval pages.) Normally two hours should be reserved for the defense. The student is responsible for ensuring that a room is reserved for the defense; the advising office can help with this if needed. To book a room in Peterson, visit the department's room calendar page.   Deadline: Several weeks before the exam.
  • The  Request for Final Examination  must be received by the Graduate and Profesional School at least 10 working days before the exam. An electronic copy in plain text (ASCII) of the title and abstract of the dissertation must be emailed to the advising office before  the student brings the request for final examination, already signed by the chair(s), to the advising office for the department approval signature. The advising office will submit the request to the Graduate and Profesional School and they will announce and publicize the defense once the request is approved by the Graduate and Profesional School. Deadline: At least 15 working days before the exam. The additional days are to allow department processing.
  • The student should distribute a complete draft ("nearly final form'') of the dissertation to the advisory committee. Deadline: Approximately two weeks before the exam.
  • The Graduate and Profesional School will send the advising office a  Report of Final Exam   before  the exam. It should be completed and signed by the advisory committee at the defense. The student's chair should return the  Report of Final Exam  to the advising office and they will submit it to the Graduate and Professional School. If the  Report of Final Exam  is not submitted to the Graduate and Profesional School within 10 working days of the scheduled examination, then a failing grade may be recorded. Deadline: Immediately after the exam (at the latest, within 10 working days of the exam).
