How to Avoid Failing Your Ph.D. Dissertation

I am a barrister in London who specializes in helping doctoral students who have failed their Ph.D.s. Few people will have had the dubious privilege of seeing as many unsuccessful Ph.D. dissertations and reading as many scathing reports by examination committees. Here are common reasons why students who submit their Ph.D.s fail, with advice on how to avoid such pitfalls. The lessons apply to the United States and the United Kingdom.

Lack of critical reflection. Probably the most common reason for failing a Ph.D. dissertation is a lack of critical analysis. A typical observation of the examination committee is, “The thesis is generally descriptive and a more analytical approach is required.”

For doctoral work, students must engage critically with the subject matter, not just set out what other scholars have said or done. If not, the thesis will not be original. It will not add anything of substance to the field and will fail.

Doctoral students should adopt a reflexive approach to their work. Why have I chosen this methodology? What are the flaws or limitations of this or that author’s argument? Can I make interesting comparisons between this and something else? Those who struggle with this aspect should ask their supervisors for advice on how to inject some analytic sophistication to their thesis.

Lack of coherence. Other common observations are of the type: “The argument running through the thesis needs to be more coherent” or “The thesis is poorly organized and put together without any apparent logic.”

The thesis should be seen as one coherent whole. It cannot be a series of self-contained chapters stitched together haphazardly. Students should spend considerable time at the outset of their dissertation thinking about structure, both at the macro level of the entire thesis and the micro level of the chapter. It is a good idea to look at other Ph.D. theses and monographs to get a sense of what constitutes a logical structure.

Poor presentation. The majority of failed Ph.D. dissertations are sloppily presented. They contain typos, grammatical mistakes, referencing errors and inconsistencies in presentation. Looking at some committee reports randomly, I note the following comments:

• “The thesis is poorly written.”
• “That previous section is long, badly written and lacks structure.”
• “The author cannot formulate his thoughts or explain his reasons. It is very hard to understand a good part of the thesis.”
• “Ensure that the standard of written English is consistent with the standard expected of a Ph.D. thesis.”
• “The language used is simplistic and does not reflect the standard of writing expected at Ph.D. level.”

For committee members, who are paid a fixed and pitiful sum to examine the work, few things are as off-putting as a poorly written dissertation. Errors of language slow the reading speed and can frustrate or irritate committee members. At worst, they can lead them to miss or misinterpret an argument.

Students should consider using a professional proofreader to read the thesis, if permitted by the university’s regulations. But that still is no guarantee of an error-free thesis. Even after the proofreader has returned the manuscript, students should read and reread the work in its entirety.

When I was completing my Ph.D., I read my dissertation so often that the mere sight of it made me nauseous. Each time, I would spot a typo or tweak a sentence, removing a superfluous word or clarifying an ambiguous passage. My meticulous approach was rewarded when one committee member said in the oral examination that it was the best-written dissertation he had ever read. This was nothing to do with skill or an innate writing ability but tedious, repetitive revision.

Failure to make required changes. It is rare for students to fail to obtain their Ph.D. outright at the oral examination. Usually, the student is granted an opportunity to resubmit their dissertation after making corrections.

Students often submit their revised thesis together with a document explaining how they implemented the committee’s recommendations. And they often believe, wrongly, that this document is proof that they have incorporated the requisite changes and that they should be awarded a Ph.D.

In fact, the committee may feel that the changes do not go far enough or that they reveal further misunderstandings or deficiencies. Here are some real observations by dissertation committees:

• “The added discussion section is confusing. The only thing that has improved is the attempt to provide a little more analysis of the experimental data.”
• “The author has tried to address the issues identified by the committee, but there is little improvement in the thesis.”

In short, students who fail their Ph.D. dissertations make changes that are superficial or misconceived. Some revised theses end up worse than the original submission.

Students must incorporate changes in the way that the committee members had in mind. If what is required is unclear, students can usually seek clarification through their supervisors.

In the nine years I have spent helping Ph.D. students with their appeals, I have found that whatever the subject matter of the thesis, the above criticisms appear time and time again in committee reports. They are signs of a poor Ph.D.

Wise students should ask themselves these questions prior to submission of the dissertation:

• Is the work sufficiently critical/analytical, or is it mainly descriptive?
• Is it coherent and well structured?
• Does the thesis look good and read well?
• If a resubmission, have I made the changes that the examination committee had in mind?

Once students are satisfied that the answer to each question is yes, they should ask their supervisors the same questions.

Defending Your Dissertation: A Guide

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.

So, you’ve spent countless late nights hunched over your computer, wanting to contribute something meaningful to your field. You’ve poured your heart and soul into your research, meticulously crafting each dissertation chapter. Now, there’s just one final hurdle: the dissertation defense!

This guide is here to help you prepare for a successful dissertation defense. We will also demystify the dissertation defense meaning.

Let our professional editors refine your dissertation! Learn more

Let’s start by answering the primary question: What does it mean to defend your dissertation?

What is a dissertation defense?

A dissertation defense is a formal presentation and discussion of your research work with your dissertation committee. It’s your opportunity to showcase your in-depth knowledge and defend your findings. 

What to expect: The dissertation defense process

The format of a dissertation defense can vary depending on your institution and field of study. However, most defenses follow a similar structure:

• Presentation : You’ll begin by delivering a concise and engaging presentation summarizing your research question, methodology , findings, and conclusions . This is your chance to shine and captivate your audience.
• Q&A Session : This is where the real “defense” comes in. Your committee will ask you questions about your research, ranging from clarifying specific points to exploring broader implications.
• Deliberation : After the Q&A, your committee will meet privately to discuss your defense and decide whether to approve your dissertation.
• Verdict : You’ll be called back into the room to receive the committee’s decision. They may offer congratulations, suggest minor revisions, or, in rare cases, request major revisions.

How long is a dissertation defense?

A dissertation defense is typically one to three hours long. It can vary sometimes. The presentation usually takes up the first hour, followed by an hour or two of questions and discussion.

How can I condense my dissertation into a presentation? 

Condensing a 100-page thesis into a 20-minute dissertation defense presentation certainly feels like a difficult task. But with just some focus and considerations, you can easily decide what you must focus on. 

1. Start with a title slide

On the title slide, add the details that you’ve added to the title page . This includes your name, credentials, and the title of the dissertation . You could also add the date of the presentation.

2. Don’t dwell too much on the abstract and the literature review

Summarize the abstract and literature review as briefly as you can, because the majority of your defense should be about your research. Ideally, this part of the presentation should be a peek into the research process.

3. Draw attention to why you’re carrying out your research

Delve a little into the topic’s history and background, so that you can eventually connect to it your research, and establish your work’s relevance in the field.

4. Talk about theoretical and conceptual influences 

Talk briefly about the conceptual framework of your dissertation, and the theoretical influences behind it.

5. State your research question clearly

All of this should ultimately lead to your research question. State it clearly, and explain the terms and jargon used in it, the same way you have in the dissertation itself. If there are sub-questions, elaborate on those too.

6. Focus on methods and methodology 

Delve deeply into how you carried out the research. What were the research methods used, and what was your rationale behind using it/them? Explain why your chosen methods are relevant to your project and its aims.

7. Move on to findings and observations

Talk about what came out of your research. What did you learn from it? What can be derived from the findings?

8. Establish how its relevance for future research 

Talk about the implications of your work for future research in your field, and why people should pay attention to them. If you have a list of policy recommendations or an action plan for your own research, talk about that as well.

How to prepare for dissertation defense: 5 Tips for success

Here are some practical tips to help you prepare for your dissertation defense:

1. Know your research inside out

This might seem obvious, but it’s crucial. Be prepared to answer detailed questions about your methodology, data analysis, and conclusions.

• Create a comprehensive research outline : Break down your research into main sections ( introduction , methodology, results , discussion) and create detailed notes for each).
• Review regularly : Set aside time each day to review different parts of your research. This will help keep all details fresh in your mind.
• Engage in mock Q&A sessions : Have peers or mentors ask you in-depth questions about your research. This will prepare you for unexpected queries.
• Summarize key points : Create summary sheets of your methodology, data analysis, and conclusions for quick reference.
• Stay updated : Ensure you are aware of any recent academic resource developments or publications in your research area that might be relevant during your defense.

2. Anticipate questions

Put yourself in your committee’s shoes and brainstorm potential dissertation defense questions they might ask. Practice your answers until you feel confident and comfortable discussing your research.

• Consult previous defenses : Look at past defenses in your department to understand the types of questions committee members typically ask.
• Engage with colleagues : Discuss your research with peers and ask them to pose questions they think a committee might ask.
• Draft responses : Write down answers to anticipated questions. This will help you organize your thoughts and ensure you cover all critical points.
• Practice aloud : Verbalize your answers to get comfortable with speaking them out loud. This can also help you identify any areas where you need further clarification.

3. Practice your presentation

A well-rehearsed presentation is key to a successful defense. Practice in front of a mirror, with friends or colleagues, or even record yourself to identify areas for improvement.

• Create a script : Write a detailed script for your presentation. This will help ensure you cover all necessary points.
• Use visual aids : Prepare slides that highlight key points, data, and conclusions. Visual aids can help keep your audience engaged and make complex information easier to understand.
• Rehearse multiple times : Practice your presentation several times. Start with a mirror, then move to friends or colleagues for feedback.
• Record yourself : Use a camera or smartphone to record your presentation. Watch the playback to identify areas for improvement.
• Time your presentation : Make sure your presentation fits within the allotted time. Adjust your content as needed to ensure you cover all points without rushing.

4. Master the art of calm

Nerves are normal, but don’t let them get the best of you. Practice relaxation techniques like deep breathing or meditation to stay calm and focused.

• Deep breathing exercises : Practice deep breathing techniques to help calm your nerves. Inhale slowly through your nose, hold for a few seconds and exhale slowly through your mouth.
• Visualization : Visualize yourself successfully defending your dissertation. Imagine the room, the committee, and yourself confidently answering questions.
• Mindfulness meditation : Engage in mindfulness meditation to help stay present and focused. Apps like Headspace or Calm can be useful.
• Regular exercise : Physical activity can help reduce stress and improve your overall sense of well-being.
• Adequate rest : Ensure you get enough sleep leading up to your defense. A well-rested mind is more capable of handling stress and thinking clearly.

5. Dress for success

What you wear to your dissertation defense matters. Choose professional attire that makes you feel confident and reflects the importance of the occasion.

• Choose professional attire : Opt for a suit or business casual outfit that makes you feel confident and comfortable.
• Check for comfort : Ensure your attire fits well and is comfortable to wear for an extended period.
• Grooming matters : Pay attention to grooming. Neat hair, clean nails, and polished shoes all contribute to a professional appearance.
• Test your outfit : Wear your chosen outfit before the day of your defense to ensure it’s comfortable and you feel confident in it.
• Plan for the unexpected : Have a backup outfit ready in case of any last-minute issues like spills or wrinkles.

Defend your dissertation with confidence

Remember, your dissertation defense is the culmination of years of hard work and dedication. It’s your moment to shine and share your valuable research with the world. By preparing thoroughly, practicing diligently, and approaching the defense with confidence and enthusiasm, you’ll be well on your way to achieving your academic goals.

How to prepare an excellent thesis defense

What is a thesis defense?

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 Successfully Defend Your Dissertation & Not Have a Nervous Breakdown

Today marks the 1 year anniversary of my (successful) dissertation defense. Even though things obviously worked out in my favor, that still doesn’t take away from the empathy I feel while I watch my colleagues go through this arduous process. I remember very little from the two months leading up to my defense. It’s pretty much a blur. By the time the day actually arrived, I was exhausted, exhilarated, and everything in between. I didn’t know what to feel. Others wanted me to be excited that I was “finished” (for those of you Ph.D.’s out there, you know that the defense is only one, albeit major, benchmark to graduation) while my committee members made seemingly joking remarks about “now the real work begins”. I think I felt my soul die a little bit. In preparation, I remember spending time with Google asking questions like, “tips for a successful dissertation defense”, “how to not cry in the middle of your defense” (lol), “dissertation defense examples”. While some of the information I found on the internet was helpful, I don’t really feel like anything I read really prepared me for that experience. I put together a list of tips based on my own experience and that of my colleagues, and hopefully you find some (or all) of this helpful!

Learn by watching

Sit in on other defenses. This is the best way to get an idea for the environment, content and vibe of a dissertation defense. I mean, let’s be honest we all would rather learn from other people’s mistakes than make our own. I sat in on a handful of defenses before I gave mine, and I really think it made a difference in my plan of attack. I also picked the brains of my more senior colleagues about things they wished they would have done differently. Sitting in is also a collegial act that helps build connection with other academics.

Practice makes perfect

True in most areas of life, and exceptionally true in the case of dissertation defenses (& any presentation, really). I practiced my defense so many times that I was rehearsing it in my dreams (no joke). Given that most defenses have a time limitation, practicing is essential, especially if you tend to go off on tangents. You shouldn’t be dependent on your presentation slides. A good presentor has a conversation with their audience where the slides simply serve as a roadmap for that conversation. I like to think about the advice I got from a mentor of mine who said, “Know your defense well enough that if the power went out you could keep going.” This is advice that I have carried with me into my professional life.

Suck it up & get feedback

I tend to be hyper self-critical. It sometimes impacts my desire for feedback even though I know how valuable constructive criticism can be. I can let the fear of someone criticizing my work inhibit my professional development and ultimately producing a higher quality product. So, how did I overcome this hurdle? I gave my defense slides to a couple people I felt completely comfortable with – close friends, close colleagues. It’s advantagous to get feedback from both academics and non-academics. A variety of lenses will help you view your presentation in many shades – some of which may be immensely helpful and bring new insight into your work.

Let off some steam

For those of you who are part of #BachelorNation, take a tip from Corinne Olympios and take a nap, I mean hey, “Michael Jordan took naps. Abraham Lincoln took naps.” My point is, do something that helps you relax and center yourself (something that is a good habit to develop, in general). When I’m super stressed out I take to one of two activities (sometimes both): cleaning & running. I think I’m drawn to both of these activities because they’re physical and upon completion give me a sense of accomplishment. Play “Shake it Off” and dance around a bit (totally done that before). Get on Instagram and browse photos under #puppy – there’s research to support that looking at cute things can have positive health impacts like adding 7.5 minutes (see here ) on to your life and lowering your blood pressure. You do you.

Confidence is key, so don’t bullshit

You need to know your defense presentation backwards and forwards (see “practice makes perfect”). Don’t try to bullshit your way through your results section. I know in my field this tends to be the most complex area. You need to know why you chose your analysis plan, how to explain it and how to make inferences from it. Think of your defense as a multi-course meal. This is the main course of your presentation, and it’s the longest course of the entire meal. If all of a sudden your meal went from salad to desert you would be wondering why, and so will your committee. Knowledge is power here.

Plan a post-defense reward

I had a bottle of champagne in my fridge for two months with a tag that said “Do not drink until after defense”. It was a solid motivator during that last week when all I kept thinking about was how once I was finished I could come home, pop that champagne, and celebrate this amazing accomplishment. Find something to reward yourself with that can help keep you motivated – a trip, that cute dress you’ve been eyeballing, a night out with friends, or in my case, a bottle of champagne. Celebrate! You deserve it, Dr.!

Here are a few tips for the day of :

• Don’t have too much caffeine. You’re already going to be hyped up and pumped full of adrenaline. Have your normal morning cup of coffee/tea and then cut yourself off.
• Try to schedule your defense earlier in the day (you don’t want to be waiting around all day).
• Dress to impress. Research shows that if you feel confident in what you are wearing that you are more likely to perform better in a task. Rock that #bosslady/#bossman outfit.
• Get there early. You do not want to be rushing. Worse. feeling. ever.
• Invite some friendly faces. You’ll want to have some people you can trust in the audience that will nod enthusiastically while you’re talking about your research.

What other tips and tricks do you have to help get through stressful academic moments like this? Comment below?

WORK WITH ME

Thank you for sharing your tips and experience. I will be defending in a matter of weeks. I fully understand the varied emotions and feelings that you talked about. I am looking forward to completing this MAJOR milestone.

Wow – congratulations! This is a huge accomplishment. Going through this process, is just that – a process. You will be processing all those emotions as you continue to prep and then afterwards. Just remember that, assuming you prepared the way you’re supposed to, you are the expert on your topic the day you present. Go into it with confidence! I wish you all the best the day of!

Picture this: after countless hours of research, writing, and refining, you’re now standing on stage with your cohort, in a gown and funny hat, because … you’ve finally completed that last important milestone in your academic journey – defending your doctoral dissertation. It’s a culmination of years of dedication, determination, and sleepless nights.     You’re not there yet—but you’re close. So how do you make it past this final, nerve-wracking hurdle?  

In this article, we’ll deep-dive into the dissertation defense process, with tips, strategies, and straight-up information. I’ll share my expertise as a coach whose job it is to get people up on that stage.  

What to expect during the dissertation defense

A dissertation defense typically consists of an oral presentation to your dissertation committee, who have already received and read the final draft of your dissertation manuscript. Other members of your cohort and institution, and outside readers or experts, might also be present in the audience.  

Without fail, I see two different reactions to this news from my coaching students: either they are terrified of having their work scrutinized by their committee in public, or they are extremely laid back, knowing that they’ve already done all the hard work in the manuscript. (These later students are the ones paying attention to me).  

You probably already know the general gist of what happens in a defense presentation: you present the highlights of your study, the committee ask questions, and then they vote on whether you pass or need to complete further revision. So, here are some things you might not yet know:

• The oral defense gives the committee the opportunity to ask you about any areas of your study that are still unclear or weak on paper – so that you can prove they are not unclear or weak in real life. In other words, it’s a chance to get anything that got stuck in your head (rather than making it on to paper) out and in front of your committee.

• Your chair or supervisor and committee should not be allowing you to complete the defense process unless they are already confident that the biggest issues with your work have already been resolved.

• Questions are normal – your committee are working with you because your work interests them (hopefully), so questions are as likely to indicate their excitement about your work as a problem they have spotted.

• Revisions are normal – from requests to polish the grammar to insisting you add more supporting sources or develop your recommendations more thoroughly, “pass with revisions” is a normal, common, and expected end result. To pass with no revisions is pretty rare (although I have had a few students achieve this – looking at you, YY!) – like getting 100% on a calculus test in school.

In short, your defense presentation is nothing to be scared of. You are lined up for defense because both you and your committee feel you know your stuff, and now all you need to do is share what you’ve produced and learned and engage people in discussion about it. You got this!

Preparing for Your Dissertation Defense

Still nervous? Ok, that’s fair enough. As with many things, good preparation can help you get those nerves under control, so here are some top tips to help you get ready.

Tick the Boxes

It’s essential to understand the requirements and expectations of your defense committee. Get familiar with the specific guidelines and procedures set by your institution, and make sure you meet all necessary criteria. If you’re giving them what they ask for, you are definitely off to a strong start.

Know Your Stuff

This defense is about you showing off what you know, so before you stand up in front of the crown, take a deep dive into your own research masterpiece. Thoroughly review your dissertation, scrutinizing each chapter, section, and argument. Make notes. Look for anything that might provoke questions or debate. Remember, this is your opportunity to showcase your expertise and demonstrate the depth of your knowledge.

Seek Wise Counsel

Your advisor and committee members are the best resources you could ask for about defense. They set the guidelines, and they judge whether you have done well. Reach out to them for guidance, feedback, and advice—their collective wisdom and support can be instrumental in honing your presentation. And, if they are not all that … well, remember there are others out there who can help, including coaches, mentors, and past students.

Just like any performance, practice makes perfect. Take the time to rehearse your presentation multiple times, refining your delivery and strengthening your command over the content. By doing so, you’ll build confidence and ensure a smoother delivery when the day arrives. Even more importantly, you’ll settle the key points of your study firmly in your brain, making sure you sound like the expert you are.

Anticipate the Unknown

Obviously, you can’t predict every question or comment that will come up during your defense. However, you can still prepare yourself for potential challenges. Get cozy with the research landscape in your field and the interests of your committee members. Step outside of your own perspective and view your work through a stranger’s eyes to anticipate areas of critique or alternative viewpoints. This will enable you to respond thoughtfully and demonstrate your ability to engage in scholarly discourse.

Managing Nerves and Anxiety

You know what’s coming and you know how to prepare – are you still nervous? If so, know that that is completely normal. Here’s how me and two of my students got their dissertation defense nerves under control.

An Awesome Supervisor

For my own dissertation defense (known as a viva voce in the UK), I was incredibly lucky to have a supervisor with whom I had a strong, supportive, and nurturing relationship. Although the main examination of my work was handled by the external reader, who sat across from me behind a big desk, my supervisor sat behind him and nodded and smiled encouragingly every time I said something. Words can’t describe how much that calmed me down and gave me confidence. If you are as lucky as me and have an awesome supervisor, tell your nerves they can stand down – your supervisor’s got your back!

You Can Get Used to Anything

One of my students, who graduated last year, suffered from terrible defense nerves because she was worried about holding so much complex information in her head and delivering it coherently. Her solution? She practiced endlessly, over the course of about a month.

With me as her coach playing the role of audience, or with her kids and other family members, her cohort peers, her dog, and even other academics, she presented that study until she could do so in her sleep. The point was that, by the time the actual defense day rolled around, presenting the study to people was comfortable, familiar territory. Done and dusted!

Temporary Denial

Another student, who graduated shortly after, took completely the opposite approach to managing dissertation defense nerves. This student was burnt out from a huge rush to meet an unexpectedly tight deadline for the final manuscript when her chair decided to retire at the last minute. Rather than burn herself out further, she hit send on the manuscript, paid a designer to polish the design of the presentation rough draft, and then shut down her devices and went on holiday with her family. For one week, she did not look at or talk about her research at all. Instead, she sat on the beach, ate ice cream, and scrolled Instagram (probably). Then, she returned to work (a week before the presentation), refreshed and feeling excited about her work again. The break enabled her to practice and prepare in a calm frame of mind.

Some Parting Thoughts

I won’t walk you through the other obvious stuff, like what makes a good presentation PowerPoint or how body language and appearance can improve your presentation skills—that stuff is what Google is for. You’re an expert by now at finding the information you need, so get out there and find it. However, know that if you need help getting ready for your defense, there are definitely humans around you (and some dogs) who want to help – whether that’s your chair, your family, or a coach like me. I recommend you find them now and let them tell you just how ready for this you are.

Practical Research Guidance

"The publications and resources helped me get a first-class degree." – Joanna Dunlop, MBA.

Failed your thesis? What next?

Your results have just been released. Hopefully you have been successful in your studies and are enjoying celebrating your achievement. Unfortunately, maybe the news you receive is not so positive. You get the unwelcome message that you have ‘failed’ your thesis or dissertation. Despite your undoubted disappointment, this should not stop you from continuing to study, completing your programme and obtaining your qualification. Simply pause and ask yourself: ‘what can I do next?’

First, and foremost, it is worth noting that failing a thesis or dissertation is not uncommon. After all, for most of your degree, many of of your assessments were short, directed tasks, which accounted for relatively small credits towards your overall qualification. When it comes to your thesis, or dissertation, however, you are often left to work alone, for a long period of time. During this time, you are using a process that is relatively new to you, and which comprises a large proportion of the credits you need to complete your programme.

Take note of the proverb put forward by Thomas H. Palmer in his Teacher’s Manual . ‘Tis a lesson you should heed: Try, try, try again. If at first you don’t succeed, try, try, try again’. Unless your college’s rules say otherwise, it is usual for students to have an opportunity to submit a revised thesis or dissertation, and/or do another viva voce (oral examination). You should most certainly ‘try again’!

Review your result

When ‘trying again’, you need to verify exactly what your result means. One student we worked with contacted us in a panic. They said they had ‘failed’ their dissertation. When we looked at their transcript, it simply said the mark was ‘withheld’ (some institutions use other wording, such as ‘pending’). This did not mean that they had failed, but, rather, there was a delay in publishing their result. This can happen if, for instance, the Examination Board did not have all the information they needed, such as requiring further evidence in support of the thesis. In such cases, you will be requested to furnish additional information within a specified (usually short) timeframe before you can obtain your overall result. Occasionally, if an Examination Board is not able to agree a mark/score on the available evidence, students can be offered a viva voce examination (an oral defence of their work).

Another common result given is ‘failed, entitled to resubmit’. This indicates that you have not passed your thesis, but can resubmit all, or part of your assessment work, for further consideration by the examiners. The results for such resubmissions are typically ‘capped’. This means that if you are successful in your resubmission, you will only be awarded the lowest available pass grade. Nonetheless, it is well worthwhile resubmitting, so you can complete your programme of studies and rightfully earn your degree.

Try again. Do better

Another proverb, this time from Samuel Beckett . ‘Ever tried. Ever failed. No matter. Try Again. Fail again. Fail better’.

Assuming your overall result is a ‘fail, entitled to resubmit’ you should view this as your opportunity to ‘do better’. To help, we recommend you seek feedback on your performance. It is important to do this immediately, as information on why students fail is not normally retained by institutions for too long after the official results are published.

In some cases, the Examinations Board provides feedback in the form of a written performance profile, or report, which identifies areas where marks have been gained or lost. Performance profiles vary in the amount of detail they offer, as the content is decided by the Examination Board, who, in turn, are advised by the institute’s general assessment regulations. You will, however, receive a score/mark on each component, or part, of the thesis. You may find minor differences between your overall, examinable, score and the component-level scores on your performance profile. This can occur when the Examination Board checks and revises borderline scores and amends the overall score, accordingly. In this situation, you can be confident that your awarded score/mark is correct.

Even if you do not receive written feedback, you may be able to approach your supervisor and/or examiner(s) to request some. Most are usually willing to offer verbal observations, but will rarely give written comments, as this might cut across decisions made by the Board. Again, you should try to do this quickly, as those who are most likely to be able assist you (such as your supervisor, internal examiner, or external examiner) may be moving on to the next cohort of students. It is important to seek not just feedback, but feed-forward. In other words, to discuss with your supervisor and/or examiner how you can improve your research study, document structure and/or presentation format, when you resubmit.

Other supports

In addition, you should establish what other supports may be available to help you resubmit your work. In some colleges, your supervisor remains in place until your second submission is complete. Whereas, in other institutions, you are automatically appointed an alternative supervisor to assist with resubmission. Even if no supervision is provided, you may have access to a counsellor or mentor to help you. Regardless of what is (or is not) available, it is always worthwhile checking. The more guidance you can obtain, at this stage, the better. If no support is forthcoming from your college, seek help from other students who have passed their thesis. Find out, who, in your class, was awarded a first/distinction. Would they share a copy of their thesis with you? Could you ask for their advice on how to improve yours?

Check the rules for resubmission

Make sure you know the rules for resubmission. You need to find out when, where, and in what format, you can resubmit. Questions you may need to pose are:

When should resubmission happen? This could vary from a couple of days, to up to six months after the original submission date. If you are not ready to rework your thesis or dissertation straight away, you may be able to postpone to the next opportunity for resubmission. This could, however, be as much as twelve months away. If you are ready, confirm who is responsible for registering you for your resubmission. In some institutions, this is done automatically by the faculty; in others, you will be responsible for your own registration.

What will your institution allow you to revise? Sometimes, it is only the presentation elements of your thesis document that can be changed (such as, structure, layout, typeface, and so on). Whereas in other cases, you are permitted a total rewrite of your study. This may occur, for example, when the content is of an appropriate standard, but it contains errors related to spellings, grammar, citing and referencing. Some institutions will only allow you to alter components for which you have a fail mark (such as, if your findings are poorly written up, you may be invited to revise that chapter/section only). Others may direct you to refine, or amend, a specific section (for example, your abstract).

The viva voce

In cases where you are invited to a viva voce, or a second presentation, it is usually because the research itself is passable, but the Examinations Board wants added assurances. For example, that you carried out the work yourself, or that you fully understood the research process you followed. This may mean that you will have to prepare for an in-depth, audio-visual presentation, and/or, participate in an oral questions and answer session. If your research is genuinely yours, and you understood what you did, this should not phase you. Make sure that you prepare in advance and practice, practice, practice. It would be helpful to have a copy of your thesis document ready, with key information marked up, so that you can refer to them easily.

If all else fails?

One final proverb comes to mind here. ‘If at first you don’t succeed; try, try again; then give up, and go and do something else instead’ (anon.).

If you are not eligible for a resubmission, or if they are not available for your thesis, you should check to see if you can gain credit for the research by retaking the whole module. That is, by doing new research and submitting that in place of your original thesis, or take another module, like a taught module, instead.

Finally. most institutions have an appeals mechanism, and this is the ultimate course of action you can take. With a thesis, or dissertation, it is rare to have the result of an Examinations Board overturned. The Appeals Board, however, may offer an alternative way of obtaining credit to complete your qualification, for example, by obtaining credits on another module.

5 Thesis Defense Myths: Your Committee is NOT Out to Get You

April 16, 2018 by Dora Farkas, PhD 10 Comments

Is Your Thesis Defense Just a Formality, or Real Defense?

“Your thesis defense is in 3 weeks?” my best friend, Kat, asked me astonished when she heard that my defense date was finally approved.

“I am taking the day off from work, see you then,” she continued.

Kat drove from New York to Cambridge (over 200 miles each way) just to see my thesis defense, and she was not happy when my talk was over.

I didn’t disappoint my audience.

My talk was well-structured, and I explained all the research relevant to my thesis.

I was not in danger of “failing” either.

While my committee had high expectations from me, they asked very reasonable questions during my thesis defense.

However, I had one of those professors in my audience.

He always sat in the first row during seminars, and questioned every statement the speakers made.

During my thesis defense, however, he took it a step further.

He asked me a question that was only distantly related to my thesis, and I humbly told him I didn’t know the answer.

I was ready to continue, but he interrupted again with the same question.

I explained again that I hadn’t looked into that research question, and proceeded to move on.

But he didn’t give up.

He explained why that research question was so important and why it had to be addressed.

The room, filled over over 100 people, suddenly felt very hot.

I started to sweat under my freshly tailored dress shirt, and reached for my water bottle.

I glanced at my committee while I took a sip of water, hoping one of my committee members would interrupt this awkward dialogue.

But they just gave me blank stares.

Then,  I sighed in relief.

“No one is out to get me, “ I realized.

“They just want to see how I perform under pressure.”

I turned back to the professor and smiled at him.

I respectfully told him that I agreed with his viewpoint, and that research question would be an excellent direction for future research.

The dialogue continued for about 10 more minutes, until the professor ran out of questions to “grill me” with.

I continued my thesis defense talk without any more interruptions from the audience.

After my talk was over, my committee had a brief closed door meeting.

When they called me back in, my thesis supervisor put his hand on my shoulder, and said “You did great.”

I knew he wasn’t referring to my thesis defense (which I passed), but to how I handled the questions from the other professor.

During my after-party, one of the senior staff members told me that she had never seen that professor be so tough on anyone else.

“Don’t take it personally,” she continued. “It’s just a rite of passage to the PhD world.”

Kat, gave me a big hug, and whispered in my ear that she had to restrain herself from giving the professor a black eye during his interrogation.

“Don’t worry,” I laughed. “This was his last chance to see how far he could push me.”

It was true.

That was my last talk at that department, but I gave many other research presentations during my postdoctoral fellowship and in the pharmaceutical industry.

At almost every talk there was one person who asked 80% of the questions, and was skeptical of everything I said.

But I always kept my calm, even when I presented to high level executives in industry.

I realized that no one expected me to know all the answers, but they did expect me to take ownership of my project and know how to find the answers.

In a strange way, the verbal beating during my thesis defense, was a gift that helped me to have more confidence in myself.

How would your life be different if you knew that no one was out to get you?

Would you be more bold about speaking up during meetings, or answering questions with confidence?

Most of the myths around the thesis defense stem from the fear that if you say the wrong thing, some will get you.

They won’t.

The worst that can happen is that they will disagree with you, and you will learn something new.

Most importantly, you will gain confidence to speak up in front of others, a skill that will serve you throughout your career.

5 Thesis Defense Myths That You Can Debunk Right Now

If you’re worried about your thesis defense, take a deep breath.

The reality is that for most students, the thesis defense is a formality.

By this point in your studies, you’re on track to graduate.

If you’ve been approved to defend your thesis, your success is almost 100% assured.

Still not sure? Here are five myths about the thesis defense, that might be causing you undue anxiety.

Myth 1: If you can’t answer every question, your thesis won’t be approved.

It’s always a good idea to prepare and practice for some questions before your thesis defense.

But don’t get stuck thinking you’ll be expected to know everything in order to pass your defense.

If you’ve conducted your research and written your thesis, you’re already, by definition, an expert in your field.

Being an expert doesn’t mean you have to have all the answers.

As you know, research is a never-ending journey, and there’s always more to learn no matter your level of expertise.

Your thesis committee knows this, too.

Your thesis defense is a chance for you to show that you’ve learned how to research independently.

If you’re asked a question you’re not sure about, it’s okay to admit you don’t know.

In fact, it’s good!

Don’t try to make up an answer…your committee will see through it.

Instead, explain how you would find out the answer

Remember, if you’ve made it to your thesis defense, the hard part is over.

You’ve already had your topic approved, done your research, and survived writing your thesis.

Myth 2: Your committee wants to catch you in a mistake

No one is out to get you.

In fact, your committee is on your side.

They want you to graduate.

You’re in control; it’s your job to lead your thesis defense.

This is your research, your education, and your future that’s on the line.

It’s normal for your thesis committee to challenge you, and hold you to a rigorous standard.

While you’re settling on a thesis topic and conducting your research, it can even be preferable to have a “tough” thesis committee.

But in the end, your committee wants you to finish your thesis and get your degree.

They wouldn’t have approved your thesis for defense if they didn’t think you were ready.

Your success reflects positively on them as instructors, and on their department.

Your committee doesn’t want to see you trapped in your program any more than you do.

It’s in your committee’s best interest that your thesis defense goes well.

Don’t worry that they’ll try to pick apart your mistakes or trap you with trick questions.

That’s not why they’re there!

In many cases, a thesis defense is a great way to bring the department together and showcase interestng research.

You can even view yourself as a role model for more junior students to give them “hope” that one day they can be in your shoes.

Your committee has already approved your thesis topic, and overseen your extensive research.

They know how much work you’ve devoted to your degree, and they’re not trying to trip you up at the last minute.

Try to relax, and have confidence that you probably know more than you realize.

Myth 3: You’ll have to start all over if your thesis defense doesn’t go well.

Take a moment to contemplate your fears.

What if your thesis defense really does bomb?

Or what if your committee wants you to make changes to your thesis before you can graduate?

In the unlikely event that this were to happen, you wouldn’t be back at square one.

Usually, in cases like these, the changes that are requested are extremely minor modifications that can be done fairly quickly.

Your thesis committee isn’t going to ask you to start researching all over again, or to drastically revise your thesis.

In a typical thesis defense, there aren’t many surprises.

Your committee will already be familiar with your work.

You’ve presumably already addressed any problems with your research.

If you’ve been given approval to defend your thesis, that means your committee is already confident in you and your research.

At this stage in your grad school career, there’s almost no chance your thesis defense won’t be approved.

But even if that were to happen, it would likely be a minor issue that you could quickly fix.

Even if the worst happens and you have to make revisions to your thesis, your graduation probably still won’t be delayed.

Myth 4: Your thesis committee members are the “real” experts in your field, not you.

A few weeks before I gave one of my first talks about my thesis, my thesis supervisor gave me a much-needed piece of advice.

I had been emailing him with questions all week.

What points did he think I should emphasize in my talk?

What should I be sure not to leave out?

My thesis supervisor was patient with my questions, but he finally had to remind me to rely on my own judgement.

“Your thesis is your own original research. You know the subject matter better than I do,” he said.

Of course, hhe was right.

He was familiar with my topic, but she hadn’t been there for the hours of lab work, I had.

I realized that I was already an expert, even if I didn’t have my PhD yet.

A thesis defense is a bit like an exam where the person being tested usually knows more than the people who are testing them.

When you present your thesis, you are the one with the first-hand experience and the knowledge.

Your thesis committee may have more overall experience, but they have their own projects and areas of expertise.

They’re relying on you to present them with your research.

By writing a thesis, you have become an authority.

In fact, you might be the most informed person at your institution on your particular topic.

So approach your thesis defense with confidence.

For almost everyone present, you’ll be teaching them something new.

Myth 5: If you’ve had a rocky path to your PhD, it will definitely show in your thesis defense.

The truth is, no two graduate degrees are alike.

Everyone takes a unique path to finishing their thesis and getting their degree, and it’s almost never easy.

If you struggled to make it to this stage, take comfort in knowing that most of your peers probably thought the same thing at some point.

But a bumpy road to finishing your thesis doesn’t mean your defense won’t go smoothly.

Even if your committee meetings were tough, or your research didn’t always go as planned, think of your thesis defense as a fresh start.

Your audience wasn’t with you every step of the way.

For the most part, they have no idea what your challenges were while you were working on your thesis.

Believe it or not, some of the best talks I’ve attended have been led by colleagues who struggled to finish their degrees.

If you’re confident during your thesis defense, it’ll shine through, and you’ll have your committee forgetting all about whatever hurdles there were along the way.

How to Effectively Prepare for Your Thesis Defense

You’ve completed your research study, written your thesis, and think you’re done! If only it were this easy. Before you finish with your thesis, there is one last hurdle to overcome: the thesis defense.

What is a thesis defense?

A thesis defense is an opportunity for you to present your research study before other academic professionals who will evaluate the quality of your academic work. While a thesis defense can sometimes feel like a cross-examination in a court of law, in reality, there is no need to fear your thesis defense as long as you are well-prepared. In this article, we’ll talk about how to prepare for a thesis defense, what to expect at the defense itself, and what comes after your defense. 

Why do I have to defend my thesis?

At your thesis defense, you will discuss everything you’ve learned with a group of interested examiners who are eager to hear your thoughts.

The fundamental purpose of a thesis defense is to prove that you have mastered your subject and can be considered as a knowledgeable expert in your field, thereby allowing you to graduate successfully. For many students, a thesis is one of the first attempts at conducting original research and demonstrating that you are equipped to function as an independent expert in your field. If qualified academic professionals can assess your work, question your methods and results, and confirm that your study is sound and novel, then you meet the requirements.

The exact format and expectations for your thesis defense will differ depending on the region you study in and your institution’s rules for the thesis program. The thesis defense meeting may have just two or three examiners or may have a whole panel of examiners along with an audience. 

If the thought of facing your professors, peers, and parents to present your research study makes you feel dizzy, you aren’t alone . Moreover, a thesis defense is a great opportunity for you to hone your public speaking skills as well as talk about your research study. At your thesis defense, you will discuss everything you’ve learned with a group of interested examiners who are eager to hear your thoughts.

While the format for a thesis defense will vary, as mentioned above, most thesis defenses consist of:

• Presenting your research study (using PowerPoint or other similar tools)
• Answering questions from your thesis committee
• Receiving feedback from your thesis committee

So how can you prepare for it? Let’s talk about some important tips.

Preparing: Before the defense

It is useful to attend multiple defenses and ask others who have gone through the process what it was like.

The best way to prepare for a thesis defense is to attend other defenses at your institution so that you know what to expect. It is useful to attend multiple defenses and ask others who have gone through the process what it was like. Senior students are often happy to provide advice and can give you specific insights about particular examiners as well as details of the administrative process at your institution.

You should also talk to your thesis advisor well in advance of your defense about what to expect. Ask whether you need to shortlist your own committee, how long your presentation should be, and how long the thesis defense will be. The duration of a thesis defense varies by the degree level as well as the institution. On average, expect your defense to be at least an hour long, possibly longer for a Ph.D.

What should my presentation cover and how can I prepare it?

While preparing your presentation, also prepare a list of questions and answers that you think are likely to be asked by your committee.

You will need to prepare a presentation that will cover the details of your research study. It is wise to rehearse this presentation multiple times in advance of your thesis defense so that you will be comfortable when you actually present in front of your audience. While preparing your presentation, also prepare a list of questions and answers that you think are likely to be asked by your committee. If you can, enlist the help of a classmate or friend to be the examiner. They can ask you questions about your research study so you will be able to practice addressing these questions.

One mistake many students make is assuming that all members of their defense committee will thoroughly read their thesis prior to the defense. This is simply not always the case. For this reason, you should make sure your presentation makes sense to someone who has not actually read your thesis. A typical thesis defense presentation gives:

• An introduction to the topic
• Explains how the study is significant in the field
• Covers the main highlights of the methodology and results of the study
• Picks out the main points from the discussion and conclusion

What should I do the day before my defense?

Before your thesis defense, make sure you have backups of everything you need saved in multiple formats and multiple locations.

Before your thesis defense, make sure you have backups of everything you need to be saved in multiple formats and multiple locations. Put your presentation and your thesis on a USB drive, email it to yourself, upload it to the cloud, and print it out. Leave nothing to chance: you want to be absolutely prepared to defend your thesis short of an act of God obliterating the venue. In addition, make sure you prepare hard copies (printouts) of both your thesis and slideshow for the committee members. It need not be professionally bound at this stage, but they will appreciate having reference material on hand.

Finally, there are some practical steps to take in preparation for the thesis defense. Choose your outfit in advance (you should dress professionally) and practice presenting in it. You should also make sure you know the exact location of the thesis defense venue. Scope out the venue before your defense, if possible, so you can imagine yourself there while you rehearse. If you are presenting virtually, test all your equipment in advance and have a backup plan in case your internet goes out or your computer suddenly crashes. Most importantly, make sure that you eat well and get proper rest the night before. Don’t stay up late rehearsing last minute in the hopes of improving your chances of passing your defense. You will do much better if you are well-rested and alert. 

Time to shine: At the defense

Try to stay calm and remember you are not on trial!

What can you expect on the day of the defense?

Typically, you will enter the room, set up, and begin your presentation once the committee indicates that they are ready. As mentioned above, it is always advisable to bring hard copies of both your thesis and slideshow for the committee. That way, they can easily refer to what you are talking about as you present. Make sure you also bring a pencil and notebook with you to take notes, and some water, because you will get thirsty as you talk.

After you are done with the presentation, the committee members will ask questions. Try to stay calm and remember you are not on trial! Your committee generally wants you to succeed, but they also want you to prove that you really know what you’re talking about. Do your best to answer their questions and never be afraid to admit when you don’t know something. It is much better, to be honest than to be caught lying or making something up during your thesis defense.

After the question and answer session, depending on your institution, you may be asked to leave the room while the committee deliberates. You may also be present while they discuss the merits of your defense and make suggestions for how to revise it. Alternatively, they might adjourn to another room if there is a large audience present. After they deliberate, they will usually thank you for your time, and your defense will be over. At some institutions, they will inform you if you passed right away, while at others, you will find out after a few days. 

How does my committee decide if my work is good or not?

In general, you can expect your thesis defense and your thesis as a whole to be evaluated based on the below criteria:

• Whether the thesis meets the departmental requirements
• Whether the research study is logical and clear
• Whether the stated objectives are met in the study
• Use of primary and secondary literature
• Use of relevant and up-to-date sources
• Methodological rigor
• Your ability to critically analyze data, facts, relevant literature, and synthesize information into a coherent narrative
• Writing quality and flow
• The validity of your conclusions based on your data and analysis
• The relevance and importance of your research study in the field
• Your ability to clearly and coherently present what your thesis is about
• Your ability to answer questions about your work accurately and in-depth
• Your ability to acknowledge and consider other theories or perspectives and explain why you dismissed one theory in favor of another

In summary, the examining committee want to know:

• Did you meet the thesis criteria set by your institution?
• Did you perform high-quality research work?
• Do you know what you are talking about?

After the defense: What’s next?

After your thesis is approved, you will need to have it professionally bound and then submit copies to your university.

After your thesis defense, you should definitely celebrate and congratulate yourself for all your hard work! Unfortunately, you aren’t quite done yet. Although the committee may notify you about passing, it is also very likely that you will be asked to make some changes to your thesis before you are finally done. You should work with your advisor to finalize and incorporate any comments you received into your work as quickly as possible.

After your thesis is approved, you will need to have it professionally bound and then submit copies to your university. You will also get the chance to order copies for yourself. This process also differs by institution, so make sure you talk to the administration department to figure out what you need to do and when to complete this process.

All in all, while a thesis defense is a scary and overwhelming event, it is also an incredible achievement. Earning your degree is no small feat, and you should definitely feel proud of yourself once you have done it!

How can I pass my PhD thesis defense when nothing has been successful?

For reasons I had very little influence on, most of the projects I participated in over the course of my PhD did not produce reasonable results. I managed to get involved in small side projects and publish at least something, but those are not very novel in itself and not "on the edge of knowledge". The edge of knowledge I pushed is what could go wrong when you are a lone representative of a "service science" in a collaboration, who is asked for input in the beginning, but later overthrown. And in the end, we look at the data together and establish we can't do what we wanted with it. And part of the problem is in fact that my input was not that valued by decision makers. This take-home message is more of a meta-topic and for sure not the main result of my thesis though.

In my thesis, I will (with a heavy heart) go through those projects and discuss them. Discuss what happened, what we did and what we should have done and could have done. This writing process is a very hard piece of work to do and is taking a toll on me right now. But I am doing it and trying to detach myself from the thoughts of how these failures could end up killing my dreams of an academic career.

In my defense, I am supposed to paint a picture-perfect representation of at least one major project. I don't have any options for this. I got caught in doing small "services" to help my collaborators and starting new projects ("we will do better this time") which always ran into a roadblock (mostly before I even got significantly involved).

I do not want to whine about science in my defense. I do not want to explain what went wrong, to the people who did it sitting in the room with a plan to cheer me through my presentation. But what can I do? People usually find one "example" of what they did that worked out well and then "blow this up" to be the main point of their defense, while it might only be a small part of the work they did over the years. But I cannot find a single interesting topic with nice results. They are either trivial or failed.

Has anybody done a "fully failed" PhD defense ... and passed? How would one do this?

• negative-results

• 9 establish we can't do what we wanted with it — That is a positive result, not failure! –  JeffE Commented May 18, 2018 at 15:46
• They are either trivial or failed. - If this is true, why does your advisor think you are ready to graduate? –  Kimball Commented May 19, 2018 at 1:52
• @Kimball Because he does not see them as failed... much like JeffE. They are not "failed for all intents and purposes" and there is not nothing learned from them. The problem is more that it is fairly uncomfortable to have a defense talking only about problems you found. I don't want to be seen as the "one who criticizes research because she couldn't get results". –  skymningen Commented May 20, 2018 at 9:14
• @skymningen I don't know your research, or your results. But try to be very clear in your own mind about the distinction between useful negative results, and "nothing learned" faliures. Remember that almost any negative result is useful, even if just in preventing somebody else from spending time on trying the same thing. –  Flyto Commented May 22, 2018 at 10:45
• 1 Also, "I am supposed to paint a picture-perfect representation of at least one major project": NO project is perfect, and if a PhD candidate claimed that their project was perfect - that nothing had gone wrong, and nothing could be improved in hindsight - some exaiminers might be surprised! –  Flyto Commented May 22, 2018 at 10:46

The specifics here are certainly best discussed with your advisor. They should know about your discipline, and how to frame results in a way that is suitable for the community.

For me, it does not sound at all like you "failed" in your PhD. A PhD is a research project, not a product. Ultimately, you (and your committee) should not evaluate your results based on whether they ended up being useful, but based on whether you had a reasonable thesis and a thorough scientific study of this thesis.

That is, if you proposed a novel approach, collected reasonable data, and thoroughly validated your initial thesis, your research was successful , independently of whether this approach then ended up being used in the larger project context. Sure, it would be nice to be able to say that your approach has then helped these other people to do A, B, C, and D, but the real world does not always work like that.

To me, it is mainly a question of mindset. If you yourself consider your PhD "failed" you will have a hard time selling it to a committee. You need to embrace the idea that you did good research, and not measure the success of your own work on factors outside of your control. In that sense, you should defend what you did and why. You can, and maybe should, discuss why it ended up not being used if there are interesting lessons learned, but stay away from political or interpersonal arguments (these can indeed sound whiney). Stay positive and focus on what you did, not on how much other people then liked the results.

• I do not consider my PhD failed and I am currently doing well with writing (only problem there is my broken heart as some of those projects I used to be passionate for). Maybe I should just bring up my ideas on how to do it better for each example where something went wrong, without specifying that I did mention those before it went wrong, just making clear that I know how to do better? –  skymningen Commented May 20, 2018 at 9:18

The short answer is yes and it is jokingly referred to a "PhD for Effort". More importantly is why it is ok.

Having projects fail teaches you what a bad project looks like

A big part of the reason a PhD helps you grow as a scientist is because in a PhD allows you to fail. I am fond of saying "getting a PhD means you have learned how to fail productively". In a company where they lose money when your experiments don't work, someone will come along and stop you if you are heading down an unproductive path. That makes the projects more likely to succeed, but it means you never had to figure out where things were going wrong. By banging you head against the wall for the last few years you have learned what a bad project looks like so in the future you will know when to cut the cord.

You may have actually failed because you are better

There are a ton of papers out there with unreproduceable results. It has become a big problem for a lot of the top journals. Sometimes this is due to chance, but at least some of it is due to things like unintentional p-hacking. It is possible at least some of your projects went wrong because you had better experimental design or because you did a better job of analyzing your data. If you could only get a PhD for positive results it would be discouraging good scientific practices.

Projects always look less impressive to the person doing them

You have been staring at your work for years. You know all the ins and outs and all the details. Of course nothing looks novel or interesting to you anymore, you know every result like the back of your hand. Try stepping away from it for a little while or getting some fresh eyes on the results. If that doesn't work, try explaining what you did to to a little kid. It is easy for things to feel small when you are explaining the details of the experiment, but when you have to simplify things down to the bigger themes you realize how much it ties in to your field. Some of the best defenses I have gone to were basically just a set of marginally related projects tied together with a good story.

Big picture summary

Even if you didn't get the results you wanted, you became a better scientist. That is why getting a PhD is part of your "education". Instead of being disappointed in the results, step back and let yourself get excited. With fresh eyes, you may realize you have more than you think.

• Some of them definitely are unpublished because we decided not to fall into the trap of shady analysis, cherry-picking results or the likes. One is so far not published because I personally stated that I would not be okay with following a specific idea that could lead to (statistically very weak) results from rather bad input data because I consider the method to obtain this fraud or at least deception. –  skymningen Commented May 20, 2018 at 9:22
• @skymningen Good for you; it sounds like the second section definitely applies. If you really feel like you can't pull together a story out of the results you got (which you probably can) focus on your good data analysis and how it kept you from going down the wrong path and led you to the less flashy but objectively more accurate conclusion. No professor is going to feel comfortable rejecting a candidate for good scientific practices and they shouldn't because it sound like you learned exactly what you were supposed to from your PhD. –  Barker Commented May 20, 2018 at 22:23
• @skymningen Also if you want to publish some of those well executed negative results, check out PLoS One . The journal explicitly has no impact factor requirements and encourages submission of negative results because they care deeply about the quality of the research as opposed to the impact of the results. I know the journal's founder personally and the type of results you are describing is exactly why he started the journal. –  Barker Commented May 20, 2018 at 22:26
• +1 in particular for "Projects always look less impressive to the person doing them" –  Flyto Commented May 22, 2018 at 10:47
