- Thesis and Dissertation Formatting
For theses, the Purdue Polytechnic Institute has adopted the APA, parenthetical citation format as implemented by Purdue University as the format for theses and dissertations. For students in departmental or school MS programs (AT, BCM, CGT, CIT and TLI [IT]), additional information may be available on your department's graduate web site.
Formatting Your Thesis
TECH 646 (a required course for most students) assists the student in developing their proposal and therefore covers how to format the thesis or dissertation. Students who are not required to take TECH 646 may use the following guidelines to ensure their thesis or dissertation is acceptably formatted.
Foremost, students should use the University Microsoft Word Thesis template which is available on the graduate school's web site . This template has styles included within it to make formatting less cumbersome. The Graduate School also holds seminars on use of the template and following the formatting requirements.
Students should NOT use the LaTeX format provided by the university. Instead, if a student desires to use LaTeX, they should use the attached template .
Note that there are a few things that the Word template will not do. Even when using the thesis template, students must:
- Ensure that they do not use vertical lines in tables.
- Properly format captions for tables and figures (including proper italics for each).
- Ensure proper tabs for each paragraph and proper hanging indents on references.
Other specifics of the format can be seen in this example document that can be used as a guide for formatting theses and dissertations.
Formatting Review for Theses
Students are required to meet with the their Thesis Format Advisor at least two weeks before they defend their thesis. The last date to meet with the Thesis Advisor for a thesis formatting appointment is two weeks prior to the last day to defend the thesis. A thesis formatting appointment is mandatory. Students who do not meet with the Purdue Polytechnic Thesis Advisor and get the appropriate approval signature on the Form 9 will not graduate at the end of the semester.
Thesis advisors in the Purdue Polytechnic include the following:
Department | Advisor | To Schedule Appointment Contact |
---|---|---|
PhD |
The Thesis Formatting Review requires the following steps:
- Scheduling the meeting to occur before the thesis/dissertation defense.
- Submitting an electronic copy of the thesis via email to the Thesis Advisor two days prior to the review meeting for submission to the iThenticate plagiarism checking software.
- Attending the Thesis review meeting.
Note that the thesis format review does not apply to directed projects. Only theses and dissertations are reviewed for format requirements.
Scheduling Formatting Appointment
To make a thesis formatting appointment with the Thesis Advisor, students will need to email the contact shown above. Once the thesis has been approved, the student may schedule a defense. It is recommended that students make an appointment with the thesis advisor as early as possible.
Providing an iThenticate Copy
Two days prior to your scheduled Thesis Advising appointment, you should email a complete copy of your thesis as a single Word or PDF document with no images to your Thesis Advisor. After receiving your document, the Thesis Advisor will submit your electronic document to the iThenticate application to verify there is no plagiarism within the document. At the Thesis Advising appointment you will be able to review the results of the check as well as receive the electronic results.
NOTE: You should bring a USB drive or other storage media with you to the Thesis Advising appoint so that you may receive a copy of the iThenticate results.
Attending the Formatting Appointment
Please e-mail Dr. Newton ( [email protected] ) a copy of your dissertation two days prior to your formatting appointment.
Thesis Pre-review
If a student is in doubt whether their document is formatted correctly, they may email a sample from their thesis to the Thesis Format Advisor for review and comment. “Pre-review” meetings are also a possibility but must occur before the sixth (6th) week of each semester.
Three-Article Dissertation Format (Alternative)
Having an article-based dissertation is a collection of 3 (minimum) published (or accepted for publication without further revision) research articles in high quality refereed journals related to a common theme. Prior to submission to the journals for publication, the candidate must obtain approval of each article and the journals from all current Committee members. The relationship between the articles and theory bases they are drawn from must be described in an introductory chapter. Crosscutting themes, conclusions, implications and recommendations that may be drawn from across the articles must be described in a concluding chapter.
Students are required to be first author, and confirm their contributions of each article before their listings according to the following Multiple Author Policy.
Requirements
Multiple Author Policy
(Adapted from Morgan, 1984)
A author is a person who has used professional skills to make a significant contribution to a published article and who can take public responsibility for its content.
A significant contribution is a contribution without which the article would have been seriously compromised in scope or quality. A significant contribution to a research project may be made by an author in one or more of the following research phases:
- Conceptualization and design,
- Methodology and/or simulation design,
- Data Collection,
- Conclusions, and/or
- Recommendations
Types of work that are specifically excluded from this definition are as follows:
- Referring subjects to researchers,
- Performing routine laboratory work, data entry, or analysis,
- Any nonprofessional work, and
- Proofreading or correction of the format or style of the article.
Unjustified multiple authorship dilutes the value of authorship, reduces the credibility of the study and can violate the essential principle that science can advance only through the work of those who understand what they are saying.
Reference: Morgan, P. P. (1984). How many authors can dance on the head of an article? Canadian Medical Association Journal, 130, 842.
Student authors are required to confirm contributions to each paper with the following statement. My contributions within the parameters of this article are: _____________________________________________. List each author and their contribution to this article. An example may look like this style from the Transportation Research Record:
Author Contributions
The authors confirm contribution to the paper as follows: study conception and design: Author1lastname, I.; data collection: Author2lastname, X.; analysis and interpretation of results: Author3last, Z, and Author1lastname, I.; draft manuscript preparation: Author1lastname, I. and Author4last, Y. All authors reviewed the results and approved the final version of the manuscript.
A dissertation authored using this structure will need to include acknowledgement of prior publication within the respective chapter, and permission from the Journal for publication with the following statements. The Journal of ________________________ ________________________________ provided permission for me to publish this article titled ___________________________________________ in this dissertation. Please attach permission letters in Appendices.
Although each journal may have specific statement requirements, the acknowledgment should be single spaced and appear 3 single spaces under the chapter title. Consult your publisher regarding required information that should appear in this acknowledgment.
Three-Article Dissertation Contents
All dissertations will conform to Purdue Polytechnic and Purdue Graduate School formatting and format review guidelines. A typical article-based dissertation will use the following structure:
Preliminary pages
- Statement of Approval and authorship page
- Dedication (optional)
- Acknowledgments (optional)
- Table of Contents
- List of Tables
- List of Figures
Main Body pages
- Introduction of Dissertation Research and Overview of Purpose and Significance of Research. Research question(s) addressed overall, and the question(s) addressed in each published article.

Dissertations & Theses
The Purdue University Libraries collects, preserves, and provides access to dissertations as original works of scholarship in conjunction with doctorates awarded by the University. Other pertinent student works such as master's and honors theses may also be collected.
What is the difference between a thesis and a dissertation?
At Purdue, “thesis” typically refers to a Master’s program and “dissertation” refers to the Ph.D program. In the early years a thesis was written in many undergraduate programs (i.e B.S. in Engineering).
How can I find dissertations that were written at Purdue?
The Purdue Libraries holds one copy of each title from 1882 to present. In some cases these have been marked confidential or have restrictions in place for a limited period of time. The original paper copies do not circulate and must be viewed in Archives and Special Collections. These can be requested through the Libraries catalog . Please log in to request your item. When the request is received, it is pulled from the storage Repository and delivered to be viewed in the Archives and Special Collections Research Center on the 4 th floor of the Humanities and Social Sciences Library (HSSE). This is located in Stewart Center, 504 W. State Street, West Lafayette, IN 47907. You will receive a confirmation email when the item is ready along with directions to the Archives.
More information:
The first Thesis is available to be viewed in Archives and Special Collections . Early Purdue University Theses and Dissertations (starting in 1882 and scanned up to 1906 so far) have been scanned and are available online. Open access copies are available online through the Theses and Dissertations, Purdue e-Puds (including some copies from ProQuest). Copies available for loan: Some of the theses and dissertations have been microfilmed and can be requested for off campus use through Interlibrary Loan (ILL) . Also, some paper duplicates will show up in the catalog, please request the copy that does not say “Only viewable in the Archives.” Alumni can request an electronic copy of their theses or dissertation from the past by contacting [email protected]. If you have questions about depositing your thesis or dissertation, please contact the graduate school Thesis and Dissertation Office .
How can I find theses or dissertations from U.S. institutions?
Go to Dissertations and Theses (PQDT) . It offers a comprehensive listing of bibliographic entries for theses and dissertations in the Dissertation Abstracts database. Theses and dissertations listed since 1997 are available in PDF digital format for users affiliated with Purdue University with access to theses and dissertations from CIC institutions. For those entries not full-text, 24-page previews are available. For non full-text entries and possible borrowing of non-Purdue titles, consult Interlibrary Loan .
How can I find dissertations that are free?
- From Center for Research Libraries (CRL) search for available paper-bound titles. CRL has more than 750,000 uncataloged foreign [non-U.S. or Canadian] doctoral dissertations, of which approximately 20,000 are presently in this database. Please consult with CRL if you are unable to find a dissertation that you may require.
- Cybertheses permits access to selected French dissertations from 1972 to the present. This database can provide access to another index where full-text provision for selected dissertations [theses in French] may be provided.

Learning Based Image Analysis - Quality Assessment, Tracking and Classification
This dissertation presents four distinct studies in the fields of image processing and machine learning, focusing on applications ranging from quality assessment for raster images in scanned document and virtual reality facial expression tracking to compression for continual learning and food image classification. First, we shift the traditional focus of image quality assessment (IQA) from natural images to scanned documents, proposing a machine learning-based classification method to evaluate the visual quality of scanned raster images. We enhance the classifier's performance using augmented data generated through noise models simulating scanning degradation. Second, we address the challenges of virtual facial animation in immersive VR, developing a domain adversarial training model to generate domain invariant features and combined it with manifold learning methods for accurate facial action unit (AU) intensity estimation from partially occluded facial images. Third, we explore the use of image compression to increase buffer capacity in continual machine learning systems, thereby enhancing exemplar diversity and mitigating catastrophic forgetting. Our approach includes a new framework that selects compression rate and algorithm, showing significant improvements in image classification accuracy on the CIFAR-100 and ImageNet datasets. Finally, we combine class-activation maps with neural image compression in food image classification systems to adapt to continuously evolving data, extending buffer size and enhancing data diversity, which is validated on food-specific datasets and shows potential for broader applications in continual machine learning systems. Together, these studies demonstrate the versatility of image processing and machine learning techniques in addressing complex and varied challenges across different domains.

When writing a long document such as a thesis or dissertation over a sustained time period, writers may find it difficult to stay motivated and make progress. Some institutions offer “dissertation retreats” or camps for helping writers make progress. An Intensive Writing Experience (IWE) is a similar event in which a writer makes a concerted effort both to make progress on a document and to become a better writer. The writer sets aside a predetermined amount of time in order to make progress on a particular writing project, such as a dissertation. The material here is meant to be used to conduct a Personal IWE that a writer can use when a group event such as a retreat or camp is not available.
This section contains detailed directions for setting up a Personal IWE. We've included vidcasts and handouts useful for a potential three-day event covering a variety of writing-related topics. Writers can view the vidcasts and read through the handouts and then apply what they have learned to their own writing. We suggest starting with the handout entitled “Conducting a Personal Intensive Writing Experience (IWE)”; this will provide details for structuring time and offers a schedule for the order of topics across a multi-day event.

Make a gift support the college.
![purdue thesis Dr. Michelle Tucker](https://vet.purdue.edu/news/wp-content/uploads/2024/08/1-Image-Headshot-2x1-11-1024x512.jpeg)
Dr. Michelle Tucker, Purdue Veterinary Medicine assistant professor of large animal surgery, received special recognition by her alma mater, the Texas A&M University School of Veterinary Medicine & Biomedical Sciences (VMBS). Dr. Tucker is one of seven Texas A&M VMBS alumni recognized in May at the college’s 2024 Outstanding Alumni & Rising Star Awards Ceremony. Dr. Tucker received the Rising Star Award, which honors Texas A&M VMBS graduates who completed their education within the last 10 years and have made significant professional accomplishments early in their careers including public service and volunteer activities that serve to positively reflect upon their alma mater. Dr. Tucker was recognized as a rising star in large animal surgery, driven by her exceptional surgical skills, passion for research, interdisciplinary knowledge, and mentoring abilities. After earning her Texas A&M DVM degree in 2014, Dr. Tucker completed two equine internships, one in private practice and one at Kansas State University. She then pursued advanced training at the University of Saskatchewan’s Western College of Veterinary Medicine, completing a residency program in 2020 and becoming board certified in large animal surgery by the American College of Veterinary Surgeons. “Dr. Tucker enthusiastically embraced all types of surgical patients, having a penchant for difficult and complex cases,” a nominator said. “Our caseload at Western College is about 70% horses, and the remainder was cattle, sheep, goats, and camelids. She nevertheless took on the non-equine caseload and developed considerable expertise in managing those cases.” In 2021, Dr. Tucker earned her PhD in large animal clinical sciences at the University of Saskatchewan and joined the Purdue Veterinary Medicine faculty as assistant professor of large animal surgery in the Department of Veterinary Clinical Sciences. Dr. Tucker’s PhD thesis was on using new technology to improve surgical correction of upper airway obstruction in horses, and she is now continuing her research into 3D airway modeling that may be used to predict patient outcomes of different equine surgical procedures. One of her award nominators emphasized that Dr. Tucker has published her PhD work in top-tier veterinary journals and presented her research at major national and international conferences. With the benefit of her bachelor’s degree in biosystems engineering and biology from the University of Kentucky, Dr. Tucker also received praise for navigating various disciplines to not only expand her own knowledge but also to set a new standard for comprehensive and holistic animal care. “Dr. Tucker collaborated with many throughout her Ph.D. program and into her post-doctoral position, seeking out relationships with somewhat unexpected groups, such as engineers, physicists, and 3D printing designers,” one nominator said. “I am confident this is the type of interdisciplinary vision that will open countless One Health possibilities for her in the future and keep pushing the boundaries of what veterinary medicine can achieve.” Dr. Tucker also was praised for her role in mentoring students, interns, and residents and her enthusiasm for teaching and training future professionals.
Congratulations Dr. Tucker!

Working scientist profiles
This article is part of an occasional series in which Nature profiles scientists with unusual career histories or outside interests.
Terry Jo Bichell sensed there was something different about her fifth, youngest child when he was just a baby. At first, doctors and friends told her that she was being neurotic, that there was nothing wrong. But when the boy, Lou, couldn’t sit up properly at the age of one, a paediatrician decided to run some tests.
A blood test revealed that Lou had Angelman syndrome, a rare developmental disorder with symptoms such as impaired motor function, limited or no speech, seizures and difficulty in sleeping. It affects one in 12,000 to one in 20,000 individuals, and there is no known cure.
Bichell heard about this diagnosis in 2000 in San Miguel de Allende, Mexico, where she was teaching at a midwifery school at the time. She remembers that, soon after, she walked half an hour to get to an Internet-connected computer to learn more.
But merely reading about Angelman syndrome didn’t satisfy Bichell. She wanted to help to find a cure, or at least a treatment — even if it meant becoming a scientist herself.
In July 2000, Bichell flew to Finland with her mother and the baby to attend the first major international conference on Angelman syndrome in Tampere. “It was the first time I had really been interested in hard science” as opposed to health care, Bichell remembers. “And it was just fascinating. And it felt like we were on the verge of a treatment, and all we had to do was just reach through the curtain, and we’d be able to figure it out.”
Sleepless nights
Angelman syndrome is named after British physician Harry Angelman, who, in 1965, noted three children with poor muscle control and abnormalities of the brain, skull and eyes, and who frequently laughed. It wasn’t until the late 1990s that scientists identified a mutation in the UBE3A gene, on chromosome 15, as the cause. Most people have both maternal and paternal copies of UBE3A , and the condition is most commonly the result of the maternal copy being absent or damaged. Overexpression of a protein linked to the same gene has been linked to autism spectrum disorders 1 .
At the Tampere conference, Lou’s sleep challenges were exacerbated by jet lag and the long daylight hours near the Arctic Circle, and Bichell would do 3 a.m. walks with him in the hotel lobby. That’s how she got to know Arthur Beaudet, a geneticist at Baylor College of Medicine in Houston, Texas, who helped to establish the connection between Angelman syndrome and UBE3A . Beaudet found himself sleepless at the same time, and the two of them discussed starting a clinical trial in San Diego, California, where Bichell was then based. The idea was to test supplements called folate and betaine as possible treatments for Angelman syndrome, on the basis that these substances might lessen some of the symptoms. Although the trial proved unsuccessful, it led to Bichell becoming a coordinator and part-time co-investigator for research into the condition.
At that point, Bichell hadn’t trained in medicine, genetics or neurobiology. She had, at first, worked as a documentary film-maker, but her career aspirations changed during a film shoot in Côte d’Ivoire in 1986, when she saw a baby die after a difficult birth. The experience made her determined to become a midwife, and subsequent degrees in nursing and public health equipped her for her new calling.
In 2000, Bichell partnered with Lynne Bird, a clinical geneticist at Rady Children’s Hospital in San Diego, to raise funds for and undertake Angelman research projects, including the folic acid and betaine trials. In a subsequent study on the natural course of the condition, Bichell interviewed more than 100 families of children with Angelman, work that she continued at Vanderbilt University after her family moved to Nashville, Tennessee, in 2006.
Lou’s sleep difficulties persisted, and Bichell remembers feeling sleep-deprived herself while driving to Vanderbilt to teach pre-literacy skills to children with Angelman. She began to wonder whether the circadian system had some connection to the disorder. “I didn’t think that anyone else in the world would be interested in following up on those hunches,” she says.
Biology homework
Eventually, Bichell decided she couldn’t sit back and await developments that might help Lou. She resolved to train as a neuroscientist and, one day, to determine the direction of research herself. “I was almost 40 when he was born, and that meant that I was probably going to die 40 years before him,” she says. This meant that “somebody else was going to have to take care of him all that time”, so she felt she had better find a treatment for the condition.
Aged 49, she enrolled in a neuroscience PhD programme at Vanderbilt in 2009 and found herself doing homework alongside her teenage daughters, who were also studying biology.
Initially, Bichell worked in a laboratory specializing in Angelman syndrome. But when the principal investigator decided to quit research, she lost her funding to probe the very condition that she had set out to study.
To stay in the programme, she would need to redirect her energy to a topic she knew nothing about for her dissertation. So, Bichell joined the lab of neuroscientist Aaron Bowman to work on Huntington’s disease, an inherited neurodegenerative condition. In retrospect, she appreciates the shift. “It expanded my mind beyond just Angelman syndrome, so then I was able to learn about a lot of other disorders and think more globally,” she says.
But the question of how the circadian system plays a role in Angelman continued to nag at Bichell. At Vanderbilt, she found an ally in Carl Johnson, who specializes in studies of circadian rhythms but knew little about Angelman syndrome. “She basically sucked me into this,” he says. Johnson had a small grant to support her investigations, which led to peer-reviewed papers demonstrating links between circadian rhythms and the condition 2 .
Being a PhD student in her fifties came with challenges. Whereas most graduate students could check on their experiments in the evenings, Bichell needed to pick up her children from school, take them to sporting events and cook their meals. (Lou attended Nashville public schools with the help of an educational assistant.) She would sometimes set an alarm in the middle of the night so that she could have uninterrupted research time on campus. “I would be there in the dark with all those creepy lab sounds going on, and nobody else there,” she says.
One night in 2010, while 11-year-old Lou, his father and two of his sisters slumbered at home, Bichell found herself crying in the lab, unable to wipe her tears off her nose because her hands were in a sterile area. “I just felt like, ‘This is horrible. What am I doing to my family? What am I doing to myself?’”
The mini-lab manager
But Birchell’s schedule became more sustainable when she created what she called a “mini-lab” of undergraduate students to work and study with her. Just as a principal investigator would, she delegated a host of small tasks to the students, but remained in charge of the experiments and analysis. The group learnt as a collective, rather than competing with one another.
“I felt like I was a mum to all my students and grad students. I was feeding the kids dinner, and then I was going back to the lab and feeding the cells,” she says. “It was all the same”, she laughs, just on “a slightly different scale”.
For her dissertation, Bichell investigated the role of manganese — which is essential for cells and yet toxic when overabundant— in mouse models of Huntington’s disease 3 . Exposing the mice to supplemental manganese led to a rebalancing of the natural urea cycle, a crucial process that mediates ammonia’s removal from the bloodstream. Her findings support the idea that the mutation in HTT , the gene that causes Huntington’s, leads to a deficiency of manganese in the brain, which contributes to increases in urea and ammonia, also in the brain. More research is needed to determine whether manganese could be involved in treatment, Bowman says.
Bowman, who now heads the School of Life Sciences at Purdue University in West Lafayette, Indiana, remembers the unusually large audience at Bichell’s thesis defence in September 2016, including the many undergraduates who had worked with her, plus faculty members, other graduate students and her family. “She got a standing ovation,” Bowman says. “I have never seen that before. Usually there’s polite clapping.”
Bichell never had expectations of going into academia after her graduation: “There’s no time for me to have a career like that,” she says. Instead, using the broadened perspectives she gained in her PhD work, she founded COMBINEDBrain, a non-profit body that connects patient-advocacy groups with clinicians, researchers and pharmaceutical companies. Its goal is to speed up research on treatments for rare genetic neurological disorders, including Angelman syndrome.
“She’s a bridge-builder,” Bowman says. Bichell’s diverse experience gave her credibility among both researchers and patient-advocacy communities, and “there are very few people in this world that can stand strong on both sides”, he says.
Combining forces
Today, Bichell’s son Lou is 25 years old. His speech is limited to “mama”, “dada” and a few approximations of other words, but he uses about 25 sign-language adaptations. Through an iPad app designed for non-speaking individuals, he can construct short sentences. He cannot be left alone in a room.
Bichell is confident that in her lifetime, a “disease-changing” treatment for Angelman syndrome will be found, and thinks that such a treatment would need to go hand in hand with widespread screening of newborns for the condition. COMBINEDBrain is one player in a large collaboration that plans to undertake a whole-genome sequencing study among infants aged 3–12 months who show signs of neurodevelopmental disorders.
Bichell is also hopeful that gene therapies will improve the quality of life of people with Angelman’s syndrome. Lou is currently taking part in an open-label clinical trial, meaning that participants know whether they are receiving an experimental therapy or a placebo. Bichell’s mother, who helped to look after Lou at the conference in Finland more than two decades ago, now assists with caregiving during the treatments in Boston, Massachusetts.
Now that their other children have grown up and moved away, the Bichell family offers rooms in their home to local musicians, who help out with Lou in exchange. Their farm includes a horse, donkey, chickens and bees. Bichell takes care of her grandchildren and teaches a translational neuroscience course at Vanderbilt. To fit everything in, she sometimes works late at night and sleeps only in short spurts, as she did during her graduate studies.
“I always have ten things going on at one time,” she says. “Eight people living in my house, ten animals to take care of, two careers. That’s the only way I really know how to do things.”

The thesis needs to be narrow. Although the scope of your paper might seem overwhelming at the start, generally the narrower the thesis the more effective your argument will be. Your thesis or claim must be supported by evidence. The broader your claim is, the more evidence you will need to convince readers that your position is right.
Suggested Order For Writing: The easiest way to build a dissertation is inside-out. Begin by writing the chapters that describe your research (3, 4, and 5 in the above outline). Collect terms as they arise and keep a definition for each. Define each technical term, even if you use it in a conventional manner.
