How to Write a Doctoral Thesis: A Complete Guide
Writing a doctoral thesis is one of the most demanding challenges in academic life. Years of research, hundreds of pages to produce, and an obligation to comply with strict standards, all under pressure from the committee, the research supervisor, and institutional deadlines. This complete guide walks you through everything from the first draft to the final submission.
1. The doctoral thesis: a long-term project
A doctoral thesis represents, on average, 3 to 7 years of work, depending on the discipline and the country. In Quebec and the French-speaking world, the target duration is generally 4 to 5 years for a full-time PhD. The stakes are twofold: producing an original contribution to knowledge in your field, and presenting it in a document that respects the formal requirements of your university.
Unlike a master’s thesis, a doctoral thesis is evaluated on its novel contribution to knowledge. Your committee expects not only methodological rigour, but also independent critical thought.
2. Typical structure of a doctoral thesis
The structure varies by discipline, but here are the standard sections of a thesis in the humanities and social sciences:
Preliminary pages (Roman-numbered pages)
- Title page
- Identification of the committee
- Abstract (French and English)
- Table of contents
- List of tables and figures
- List of abbreviations
- Dedication and acknowledgements (optional)
Body of the thesis
- General introduction: research problem, objectives, hypothesis or research question, outline
- Chapter 1: Literature review: state of knowledge, theoretical positioning
- Chapter 2: Theoretical and conceptual framework: foundational concepts, models used
- Chapter 3: Methodology: research design, data collection and analysis
- Chapters 4 to 5+: Results and discussion: empirical analysis, interpretation
- General conclusion: synthesis, limitations, future avenues
Supplementary pages
- Bibliography / References
- Appendices
- Index (if required)
For engineering, science, and mathematics disciplines, the structure may incorporate published articles (article-based thesis). Check the regulations of your program.
3. Writing timeline: planning over 6 to 18 months
Most doctoral students underestimate the time needed for writing. Here is a realistic schedule for the last 18 months of the doctorate:
| Phase | Duration | Main tasks |
|---|---|---|
| Preparation | 1-2 months | Finalize data collection, structure the data |
| Chapter writing | 6-12 months | Write chapter by chapter, iterate with the supervisor |
| Overall revision | 1-2 months | Consistency, transitions, argumentation |
| Formatting | 2-4 weeks | Institutional standards, bibliography |
| Submission and defence | 1-3 months | Official submission, oral preparation |
Key tip: do not wait until you have all your data to start writing. The literature review and the theoretical framework can often be written as early as the second year.
4. What your committee expects
A thesis committee evaluates four main dimensions:
- Originality: does your contribution bring something new?
- Rigour: is your methodology solid and well justified?
- Consistency: do the parts fit together logically?
- Command of the field: do you demonstrate a deep knowledge of the literature?
On the formal side, committees immediately notice layout problems, repeated citation errors, and inconsistencies in section numbering. A poorly formatted thesis undermines your credibility, even when the substance is excellent.
5. Formatting requirements at Quebec universities
Each university has its own guidelines, but here are the standards common across Quebec:
- Margins: 2.5 cm (sometimes 3 cm on the left for binding)
- Font: Times New Roman 12 pt or Garamond 12 pt
- Line spacing: double in the body text, single for long quotations and notes
- Pagination: Roman numerals for the preliminary pages, Arabic numerals starting from the introduction
- Chapters: always begun on an odd (recto) page in bound versions
These requirements apply to the version submitted to Papyrus (UdeM), Archimède (Laval), ARCHIPEL (UQAM), or your institution’s platform.
The problem: applying all these requirements manually in Word or LaTeX takes days. A single wrong heading style can throw off the entire numbering. That is exactly the problem Uniformat solves.
Uniformat analyzes your document and automatically generates formatting that complies with the standards of your Quebec university. No more redoing your table of contents by hand after every change.

6. Citations and bibliography: choose and follow a style
Consistency in citations is non-negotiable in a doctoral thesis. The most common styles in Quebec:
- APA 7 (social sciences, education, psychology)
- Chicago (history, philosophy, arts)
- Vancouver / AMA (health sciences)
- IEEE (engineering, computer science)
Use Zotero to automate reference management. Install the Word or LaTeX plugin, configure your house style, and Zotero inserts and updates your citations automatically. It is a considerable time-saver on a bibliography of 200+ references.
7. Recommended tools for writing your doctoral thesis
| Need | Tool |
|---|---|
| Reference management | Zotero |
| Word processing | Word or LaTeX |
| Institutional formatting | Uniformat |
| Language correction (French) | Antidote |
| Organization and planning | Notion |
| Collaboration with supervisor | Google Docs or Overleaf |
8. Conclusion
Writing a doctoral thesis is a demanding intellectual ordeal, but also a unique academic adventure. The key is to work methodically: structure early, write regularly, and do not neglect the formatting.
To avoid losing weeks at the end of the journey fixing your layout, use Uniformat from the start to make sure your document complies with the standards of your university.
