Submitting a PhD thesis is one of the most significant milestones in a scholar’s academic journey. Yet, one of the least discussed—but critically important—steps is the process of selecting external examiners or reviewers. The choice of evaluators can shape not only the defense process but also the credibility of the thesis and the scholar’s career trajectory.
Finding suitable experts is both an art and a science. It requires a balance between academic integrity, fairness, subject expertise, and institutional rules. Below, I’ll share practical strategies, subtle tricks, and hidden considerations that often go unspoken in academia.
1. Understand the Official Guidelines First
Before shortlisting names, start with the rules of your university or research council:
-
Many institutions require evaluators to be from outside the candidate’s university.
-
Some may mandate international reviewers.
-
There may be restrictions on professional closeness—co-authors, collaborators, or project partners are often disqualified.
-
Examiners may need to be of a certain academic rank (e.g., Associate Professor or higher).
π Tip: Universities sometimes reject lists because nominators ignored these eligibility rules. Always cross-check.
2. Define the Expertise Required
A PhD thesis is usually multidisciplinary at some level. Think about:
-
Core expertise: Does the expert have published work in the exact subfield?
-
Methodological expertise: If your thesis uses novel methods, you may need someone who can fairly evaluate them.
-
Theoretical grounding: Sometimes, a strong theorist balances a method-heavy reviewer.
π Hidden consideration: Choose at least one examiner who can appreciate the broader impact of the thesis, not just the technical details. This helps avoid overly narrow or nitpicky criticism.
3. Balance Reputation with Fairness
Big names add weight to your evaluation report—but they also come with risks:
-
Senior scholars may be too busy to give timely feedback.
-
Highly established figures can sometimes be harsher, to protect their field’s standards.
-
Mid-career scholars are often more responsive and invested in writing a fair report.
π Trick: Mix reputational weight with practicality. Propose at least one highly cited, senior expert, and one younger but rising scholar.
4. Search Strategically for Candidates
Here are practical search strategies:
-
Scopus/Web of Science/Google Scholar: Look at who cites or is cited by your thesis’ key references.
-
Editorial boards of relevant journals: Editors are active in the field and often considered credible evaluators.
-
Conference keynote speakers and session chairs: They are visible, respected, and usually open to evaluation roles.
-
Grant reviewers or advisory boards in your field: Their names are often public.
π Hidden trick: Search for reviewers who have written book reviews or review articles in your area. These scholars have demonstrated balanced judgment.
5. Avoid Conflicts of Interest
This is one of the most common reasons lists are rejected. Avoid:
-
Recent co-authors, collaborators, or grant partners.
-
Scholars from the same institution or research network.
-
Advisors of your supervisor (academic genealogy matters).
π Hidden consideration: Even if there’s no formal collaboration, avoid names with strong personal ties (close friends, former lab mates). These connections are sometimes flagged informally.
6. Assess Practicality and Reliability
Even if someone is a world-class expert, ask:
-
Do they respond to emails reliably?
-
Are they known for meeting deadlines?
-
Do they write thoughtful reviews (if you know through networks)?
π Trick: Scan their publication record over the last 3 years. If someone is consistently publishing, they’re likely still active and reliable. If not, they might decline or delay.
7. Think About Diversity and Optics
Institutions are increasingly sensitive to diversity and fairness in examiner selection. Consider:
-
Geographic diversity: Don’t propose only scholars from one country.
-
Gender diversity: A balanced list signals inclusivity.
-
School of thought diversity: Having examiners from slightly different perspectives makes the evaluation more balanced.
π Hidden consideration: A diverse panel often strengthens the perceived legitimacy of the defense outcome.
8. Strategize the Presentation of the List
Often, supervisors are asked to propose a list of 5–10 names. The institution then selects a subset.
-
Rank the names strategically: put the most suitable at the top.
-
Provide a one-line justification for each name: “Prof. X is a leading expert on genomic rearrangements, with over 150 papers in the field.”
-
Show awareness of balance (methods, geography, reputation).
π Trick: If you really want someone, subtly highlight how uniquely relevant their expertise is. Committees often prefer the “obvious” fit.
9. Use Your Academic Network Discreetly
Sometimes, informal reputation matters as much as formal credentials.
-
Ask your supervisor if they know how reliable a potential examiner is.
-
Use conferences to get a sense of how approachable a scholar is.
-
Quietly check with alumni or colleagues who had them as reviewers.
π Hidden consideration: Some brilliant scholars are notorious for sitting on reports for a year. Avoid them.
10. Prepare Backup Options
Even the best candidates may decline. Always have at least 2–3 solid backups.
π Tip: If your institution allows, give a slightly longer list than required.
Final Thoughts
Finding suitable examiners for a PhD thesis is a delicate balancing act between rules, expertise, reputation, fairness, and practicality. The hidden art lies in matching the spirit of the thesis with evaluators who will appreciate its contributions, without jeopardizing timelines or fairness.
When done thoughtfully, the right selection not only ensures a fair defense but also helps position the scholar within the global academic conversation of their field.
✨ Takeaway: Don’t just think of examiners as gatekeepers. Think of them as potential first ambassadors of your thesis in the wider academic world. Choosing wisely can shape both the outcome of your defense and the reception of your future research career.
