Grant Writing — NIH, NSF, and ERC Proposals

TL;DR — Produce well-structured grant proposal sections using Jinja2 templates (NIH Specific Aims, ERC B1/B2 narratives), auto-generate budget tables with pandas, and format reference lists with pybtex. Covers NIH, NSF, and ERC Starting Grant conventions.

When to Use This Skill

Use this Skill whenever you need to:

• Draft or refine a NIH Specific Aims page following the standard one-page format
• Structure an NSF Project Description with explicit intellectual merit and broader impacts
• Outline ERC Starting Grant B1 (extended synopsis) and B2 (scientific proposal) sections
• Generate a personnel budget justification table with fringe, indirect, and total costs
• Format an NIH Biosketch (personal statement, positions, contributions to science)
• Write a 250-word structured abstract with labeled sections for any funding agency
• Format a BibTeX reference list using pybtex for grant submissions

Task	When to apply
Specific Aims page	NIH R01, R21, K-series, SBIR/STTR submissions
NSF Project Description	NSF CAREER, standard grants, RAPID, EAGER
ERC B1/B2 narrative	ERC StG, CoG, AdG applications
Budget justification	Any sponsored research with modular or detailed budget
Biosketch	NIH applications; NSF equivalent (Facilities & Other Resources)
Structured abstract	Journal submission cover letters, conference abstracts

Background & Key Concepts

NIH Specific Aims Page

The Specific Aims page is the single most important page in an NIH application. Reviewers read it first and it determines whether the full application receives detailed review. The canonical one-page structure is:

1. Opening paragraph — Establishes the research problem, knowledge gap, and why the problem matters (~100 words).
2. Long-term goal — The overarching scientific objective beyond this grant.
3. Objective — What this specific project will accomplish.
4. Central hypothesis — A testable, falsifiable statement derived from preliminary data.
5. Specific Aims list — Typically 2–4 aims, each with a brief rationale and expected outcome.
6. Innovation — What is new about the approach or the scientific question.
7. Impact — Expected contribution to the field and public health relevance.

NSF Project Description

NSF requires explicit separation of intellectual merit (advancing knowledge within a field) and broader impacts (benefits to society). Page limits vary by program (typically 15 pages for standard grants, 20 for CAREER). Word count guidance:

Section	Typical length
Introduction & significance	1–2 pages
Preliminary results	2–3 pages
Research plan (each aim)	2–3 pages per aim
Intellectual merit summary	0.5–1 page
Broader impacts	1–2 pages
References cited	Does not count toward page limit

ERC Starting Grant B1/B2 Structure

Section	Description	Page limit
B1 — Extended synopsis	Short self-contained overview of the project	5 pages
B2 — Scientific proposal	Full research plan: state of the art, methodology, resources	15 pages

ERC reviewers assess scientific excellence (novelty, ambition, feasibility) and principal investigator quality (track record, independence).

Budget Categories

A typical NIH R01 modular budget ($250 K/year direct costs) or detailed budget includes:

Category	Description
Personnel	PI, co-I, postdocs, graduate students, technicians
Fringe benefits	As percentage of salary (typically 25–40 %)
Equipment	Items ≥ $5 000 with useful life ≥ 1 year
Travel	Domestic + international conferences
Materials & supplies	Lab consumables, software licenses
Other direct costs	Publication fees, patient costs, subcontract
Indirect (F&A)	Negotiated rate × modified total direct costs

Structured Abstract (250 words)

All NIH applications require a structured abstract with labeled sections: Background, Objective, Methods, Expected Results, and Significance. The total must not exceed 250 words.

Environment Setup

# Create a dedicated virtual environment
python -m venv .venv
source .venv/bin/activate  # Windows: .venv\Scripts\activate

# Install required packages
pip install "jinja2>=3.0" "pybtex>=0.24" "pandas>=1.5" "python-dotenv>=1.0"

# Verify installation
python -c "import jinja2, pybtex, pandas; print('Setup OK')"

For AI-assisted draft generation, set your API key:

# export OPENAI_API_KEY="<paste-your-key>"
# export ANTHROPIC_API_KEY="<paste-your-key>"
python -c "import os; print(os.getenv('OPENAI_API_KEY', 'NOT SET'))"

Core Workflow

Step 1 — Render NIH Specific Aims Page with Jinja2

Define your grant content as a Python dictionary and render a structured Specific Aims page using a Jinja2 template.

load_dotenv()

Advanced Usage

NIH Biosketch Formatting

The NIH Biosketch (Form PHS 2590 / SciENcv format) contains four sections:

1. Personal Statement — 4 sentences maximum. State why you are well-suited for this project. Reference up to 4 publications.
2. Positions, Scientific Appointments, and Honors — Reverse-chronological list with institution, role, and dates.
3. Contributions to Science — Up to 5 paragraphs, each with a brief narrative and up to 4 publications. Describe the historical context, your contribution, and significance.
4. Additional Information — Research support (current and pending).

ERC Starting Grant B1 / B2 Outline

ERC proposals require explicit evidence of scientific excellence and PI independence. Structure B1 (5 pages) as follows:

Subsection	Content
B1.1 Overview	Project title, keywords, short abstract (10 lines)
B1.2 State of the art	Current knowledge and open question
B1.3 Objectives	3–5 numbered objectives aligned with work packages
B1.4 Methodology	Key experimental/computational approaches
B1.5 Originality	How the proposal goes beyond the state of the art
B1.6 Resources	Team composition, key infrastructure

For B2 (15 pages), expand each subsection and add:

• Work package (WP) table with lead, duration, deliverables, milestones
• Risk assessment table (risk, probability, mitigation)
• Timeline Gantt chart

NSF Broader Impacts Template

NSF reviewers score broader impacts independently of intellectual merit. Include:

• STEM workforce development — graduate/undergraduate mentoring plan
• Broadening participation — recruitment strategy for underrepresented groups
• K-12 outreach — partnerships with local schools or science museums
• Open science — data sharing, software release, preprint posting
• Dissemination — target journals, conferences, policy briefs

Troubleshooting

Problem	Likely cause	Fix
Jinja2 UndefinedError	Missing key in content dictionary	Add all required keys; use default('') filter in template
Budget rows duplicated	years parameter too high	Verify years matches Notice of Award period
pybtex PybtexError	Malformed author string	Use "Last, First" format; escape special characters
Abstract word count over limit	Run-on sentences	Use write_structured_abstract() validator; trim each section
BibTeX missing fields	Incomplete entry dict	Check required fields: author, title, journal, year
Indirect rate mismatch	Stale F&A agreement	Retrieve current negotiated rate from institutional grants office

Examples

Example 1 — Full NIH Specific Aims Page Rendered via Jinja2

# Run from the project root; requires jinja2 and python-dotenv installed
import os
from dotenv import load_dotenv
load_dotenv()

# Re-use functions defined in Step 1
text = render_specific_aims(EXAMPLE_AIMS_CONTENT)
word_count = len(text.split())
char_count = len(text)

print(f"=== NIH Specific Aims Page ({'~' + str(word_count)} words) ===\n")
print(text)
print(f"\n[Characters: {char_count} | Target: ≤ 3500 for one page at 11pt Arial]")

# Save to file for review

BROADER IMPACTS

Intellectual Merit: [Summarize contribution to fundamental knowledge]

Broader Impacts:
1. Graduate and postdoctoral training: One PhD student and one postdoc will
   receive training in [field], preparing them for careers in academia and
   industry. Mentoring will follow the Individual Development Plan (IDP)
   framework.

2. Broadening participation: We will partner with [HBCU/MSI partner] to
   host two REU undergraduates per summer from underrepresented groups.
   Travel support will be provided.

3. K-12 outreach: We will develop two inquiry-based modules for local high
   schools in partnership with [School District], reaching ~200 students
   per year.

4. Open science: All datasets will be deposited in [repository] under CC-BY
   license within 12 months of collection. Analysis code will be released on
   GitHub under MIT license.

5. Policy engagement: Findings will be communicated to [agency] via annual
   stakeholder briefings and one policy brief per project year.
