Pre-Doctoral and Postdoctoral Fellowship Application

A workflow for applying to major external fellowships, including predoctoral awards (Hertz, NDSEG, NSF GRFP, Ford, AAAS Mass Media) and the Packard postdoctoral fellowship. Covers personal statement, research statement, transcript curation, graduate school list, referee coordination, and submission timing across multiple application cycles. Produces a portfolio of application materials tailored to each fellowship, a referee plan, and a calendar of submission deadlines.

When to use

• Applying for a predoctoral fellowship as an undergraduate or early graduate student.
• Applying for a postdoctoral fellowship in the Packard, Pew, Searle, or similar private-foundation cohort.
• Building a master application that can be tailored to multiple fellowships with shared materials.
• Coordinating referees and timing across overlapping deadlines.
• Writing the personal statement and research statement required by major US fellowships.

When NOT to use

• Internal university fellowships — these are typically shorter and more institution-specific; consult your department's graduate office.
• Federal grants for senior researchers (NIH R01, NSF CAREER) — see ors-research-grants-nih-r01 and ors-research-grants-nsf-standard.
• Industry fellowships (some companies run 1-2 year programs) — these follow industry hiring norms; see ors-career-navigation-industry-transition.

Prerequisites

• A current CV (see ors-career-navigation-academic-cv).
• Transcripts (official and unofficial; most fellowships accept unofficial for application, official upon acceptance).
• A list of 3-5 potential referees: usually 1-2 research supervisors, 1-2 faculty who can speak to research potential, and optionally 1 who can speak to broader impacts.
• 1-2 page research summary that can be expanded into a full research statement.
• Knowledge of each fellowship's specific requirements (read the current solicitation — programs change year to year).
• A grad school list (for predoctoral applications): 5-10 programs, ranked by fit, deadline, and faculty overlap.

Core workflow

1. Build a fellowship matrix

Different fellowships target different populations and require different materials. Build a matrix:

Verify each program's current year's details before relying on the table. Programs revise their amounts, deadlines, and eligibility year to year.

2. Build a master CV tailored to each fellowship

Most predoctoral fellowships are early-career, so the CV is short. The CV should highlight:

• Research experience (labs, projects, methods learned)
• Publications and preprints (a single first-author paper is a strong signal)
• Awards and honors (Dean's list, research awards, conference travel grants)
• Teaching and mentoring (TA positions, tutoring, outreach)
• Service and broader impacts (society membership, conference volunteering, science communication)
• Skills (programming, methods, instruments)

For each fellowship, the CV is usually submitted in a specific format (NSF GRFP uses the NSF-approved format; Hertz uses its own portal). Tailor the emphasis: for Hertz, lead with technical depth; for NSF GRFP, lead with broader impacts; for AAAS Mass Media, lead with writing and communication experience.

3. Personal statement

The personal statement is the most read document in a fellowship application. Length: typically 2 pages for NSF GRFP; 1-2 pages for Hertz; varies for Ford. Tone: personal, specific, forward-looking.

Structure (NSF GRFP is the most codified example):

1. Opening (1 short paragraph): who you are, your research question, your broader context.
2. Intellectual merit (1-2 paragraphs): your research experience, what you have done, what you have learned, what is novel. Be specific: methods, datasets, results.
3. Broader impacts (1-2 paragraphs): how your work benefits society, how you have contributed outside the lab (mentoring, outreach, teaching, science communication), how you will continue to contribute.
4. Future goals (1 paragraph): what you will do in graduate school, what you want to accomplish, what kind of career you are building toward.
5. Why this fellowship / why this graduate program (1 paragraph): the specific opportunity, the specific program, the specific mentor(s).

Style guidance:

• Personal and specific: avoid generic "I have always wanted to be a scientist" openings. Open with a specific moment, a specific question, a specific project.
• Concrete over abstract: "I built a Python pipeline that analyzed 1,200 metagenomes" is stronger than "I am interested in data science".
• Show, do not tell: instead of "I am a strong mentor", describe the mentee, the project, the outcome.
• Connect research and broader impacts: fellowships value integration, not parallel tracks.
• Have non-faculty readers review it: a parent, a friend, a non-scientist. If they can summarize your research and your goals, the statement is clear.

4. Research statement

The research statement is longer and more technical than the personal statement. Length: 2-3 pages for Hertz, 2 pages for NSF GRFP, varies for Ford.

Structure:

1. Research question (1 paragraph): what is the problem, what is the gap, what is your approach.
2. Background and prior work (1-2 paragraphs): what is known, what you have already done, what is novel about your contribution.
3. Proposed research (2-3 paragraphs): the specific aims, the methods, the expected outcomes, the alternative approaches. Specific aims are useful even in the research statement.
4. Timeline and feasibility (1 paragraph): what you will accomplish in the fellowship period; what resources you need; why the proposed institution and advisor are the right fit.
5. Why this fellowship (1 paragraph): the unique value of the fellowship, the community, the flexibility.

Style guidance:

• Figures welcome: 1-2 well-designed figures communicate a year of work in a single image.
• Be specific about methods: name techniques, software, datasets.
• Acknowledge limitations and alternatives: reviewers respect candidates who can see the failure modes of their own work.
• Connect to the proposed advisor's work: name 2-3 papers from the proposed group that are most relevant; explain how your project fits.

5. Graduate school list (predoctoral)

The graduate school list is strategic, not just a list of programs. Build it from three columns:

• Reach: top-5 programs, lower admit rate, ideal advisors
• Target: solid-fit programs, strong advisors in your area, high admit rate
• Safety: programs where you are clearly competitive

For each program, capture:

• School and department
• Potential advisors (3-5 names)
• Recent papers from the group
• Fit notes (why you, why them)
• Deadline and fee waiver policy
• Funding offer (stipend, tuition coverage, health insurance)

Apply to 5-10 programs. More than 10 dilutes effort; fewer than 5 leaves you exposed to a bad cycle.

6. Referee coordination

The referee plan is the most underestimated part of the application. Start 6-8 weeks before the deadline.

Selecting referees:

• 1-2 research supervisors (lab PI, summer supervisor)
• 1-2 faculty who can speak to research potential
• 1 who can speak to broader impacts (a mentor from outreach, teaching, or service)
• For postdocs: 3-4 senior researchers, including the postdoc advisor, a thesis committee member, a collaborator

Asking a referee:

Send a 1-paragraph email with:

• The fellowship name and deadline
• The URL of the program
• A copy of your CV
• A draft of your personal statement and research statement
• A list of the program prompts
• The submission link and any institution-specific requirements
• A deadline at least 1 week before the official deadline

Always ask if they can write a strong letter. A lukewarm letter is worse than no letter.

What to give the referee: the materials above plus a "letter cheat sheet": the program's evaluation criteria, the points you most want emphasized, the proposed research advisor and institution, and 2-3 specific examples of your work that they can cite.

7. Transcript curation

Most predoctoral applications ask for transcripts. The official transcript is the record; the personal statement and CV contextualize it. Some applications ask for a "transcript explanation" or "academic record" section — use this to:

• Briefly explain a poor semester or a gap
• Highlight research-heavy semesters
• Note non-coursework achievements (research, internships)
• Be honest; do not fabricate

A 4.0 GPA in a tough program is strong; a 3.5 in a tougher program with research and publications is also strong. The transcript is a data point, not a verdict.

8. Submission timing and revision cycles

Most predoctoral deadlines fall in October-December for fall start; some in January for spring. The Packard postdoctoral deadline is institution-internal in January-March and national in May.

Calendar (high-level):

Revision strategy:

• Write one strong draft and adapt it for each fellowship.
• Use a single source document (LaTeX or Markdown) with section files for each program.
• Have at least 2 mentors review each draft. Different mentors catch different things.
• Do not wait for the "perfect" version; submit a strong draft by the deadline.

9. Common applications for science writers (AAAS Mass Media)

The AAAS Mass Media fellowship places graduate-student scientists in newsrooms for the summer. The application is a portfolio:

• 3-5 writing samples (news articles, blog posts, op-eds)
• A personal statement (1-2 pages) on why you want to do science writing
• Transcripts
• 2 letters of reference (often from a science writer and a researcher)

Build a writing portfolio before you apply: pitch op-eds to local papers, write blog posts, contribute to a lab blog or institutional magazine, volunteer for science-communication organizations. The portfolio is the most evaluated component.

Personal statement opening examples (avoid generic openings)

# Avoid
"I have always been fascinated by science. From a young age, I knew I
wanted to be a researcher..."

# Better
"In my second month in Dr. Garcia's lab, my qPCR plate failed twice
in a row. The third time, I changed the primer design and the data
finally made sense. That week I realized I was not just running
protocols — I was designing experiments. Three years later, I lead
the wet-lab component of a project..."

# Better still (with a specific question)
"Can a single-molecule measurement of a ribosome tell us why
translation slows in aging neurons? This is the question I have
spent the last two years learning to ask, and the question I want
to spend my PhD answering."

Research statement figure conventions

• One figure per page max; usually 1-2 figures total.
• Use the same fonts and color palette as your main paper.
• Label axes clearly; do not assume the reader knows your field's conventions.
• Caption: 2-4 sentences that stand alone, summarizing what the figure shows.
