A Hitchhiker's Guide to PhD Applications
This is a living document of resources and notes I've gathered about the PhD application process. Organised not as a checklist, but as a set of mental models — things I wish someone had told me earlier.
GAAPs
The Graduate Application Assistance Programs are your first resource. MIT EECS runs one of the most well-known:
- MIT EECS GAAP — current PhD students volunteer to read drafts, offer feedback, and answer questions. Use it.
Recommendation Letters
The single best resource I found: How PhD admissions committees read your letters
The core insight: vague praise is noise. What committees are actually looking for is specificity — stories that demonstrate the qualities of a researcher, not adjectives about how great you are.
Good letters touch on things like:
- Did the student go out of the way to propose new experiments?
- Did they overcome a hard situation while managing coursework?
- Did they show intellectual initiative, not just execution?
The objective is to convince the committee that the student's intent is aligned with research — not that they're desperate to get a PhD.
Special note for international applicants, people from smaller colleges, and people who have had unusual struggles: Ask your letter writers to contextualise your progress. A 7.5 GPA from a tier-3 college with no lab infrastructure is not the same as a 7.5 GPA from IIT. Committees know this — but only if someone tells them.
Cold Emails to Professors
A template and philosophy that actually works: TeeLabIISc — How to write an email for a research internship
Short version: read their papers, say specifically why one of them excited you, and ask a concrete question. Don't introduce yourself for three paragraphs and then ask for a position.
Statement of Purpose
Resources worth your time:
- WriteIvy — Why This Program
- Lucy Lai — Grad Applications
- Vasudha Kulkarni's Resources
- rdgao — SOP Reflections
- goodwind.in — How to Write an SOP
- CS SOP Database — read real accepted SOPs
The Four Questions Every SOP Must Answer
Though it seems like there's a lot to cover, SOP prompts always boil down to:
- Why do you want a PhD?
- What previous research experience have you had? (This is ~50% of the document)
- What do you want to do in your PhD?
- Why this school? Who do you want to work with?
The Most Important Reframe
The SOP is a science story, not a life story.
It is about convincing the committee that you are a great fit — according to their criteria as well as yours.
The "Why This School" section is where most applicants fail. It's the only place a grad school can tell whether you:
- Actually know what you're doing
- Have legitimate reasons for applying — not just prestige-chasing
- Have a realistic plan that their programme can support
Don't be Captain Obvious. "Your department is world-renowned" is not a reason. Convince them how you will make the best use of their specific resources, their faculty's specific work, their specific programme structure.
The question is never just "why us" — it is simultaneously "what do you bring to us that makes this a good match?"
