Postdoctoral Fellowship: Long-Term Fellowship

Human Frontier Science Program

HFSP Long-Term Fellowships offer a unique opportunity for researchers in the life sciences to move to a new environment and gain exposure to new biological questions, problems, and techniques. By carrying out a project that is significantly different to their previous work, as well as moving to a new country and new institution, fellows will further develop their expertise in the life sciences, expand their international network, and build interdisciplinary collaborations.

Successful LTF proposals:

• Incorporate novel investigative approaches at the frontiers of the life sciences with the potential to disrupt existing paradigms and current ways of thinking.

• Clearly show how the proposed project is different from the applicant’s research to date (PhD or previous postdoctoral experience), and how it will help the applicant to adopt new research approaches and methodologies.

• Demonstrate the applicant’s ability to formulate a research project that is frontier-extending and of a risky nature.

• Describe how the applicant’s unique training and skillset will allow them to address their project in a novel and distinct way.

• Anticipate results that will have an impact beyond the immediate research topic or field.

• Generate new research directions for the host laboratory.

AI Based Application Success Predictor

🔬 1. Frontier, High-Risk Basic Science (Top Predictor)

HFSP exclusively funds:
- Fundamental (basic) research in life sciences
Strong emphasis on:
- High-risk, high-reward ideas
- Projects that challenge existing paradigms

👉 Key question:
“Is this bold, unconventional science that could transform biology?”

🚀 2. Breakthrough Innovation & Originality (Critical)

HFSP actively seeks:
- “game-changing” and unconventional ideas
Encourages:
- Ideas that other funders might reject as too risky

👉 Incremental or “safe” projects are rarely funded

🌐 3. International Collaboration (Non-Negotiable for Grants)

Applications must be:
- Multinational teams (typically 2–4 researchers)
Prefer:
- Intercontinental collaborations

👉 Solo or single-institution projects → not eligible

🔄 4. Interdisciplinary Research (Major Differentiator)

Strong preference for:
- Cross-disciplinary teams
Especially:
- Non-biologists entering life sciences
- Integration of:
  - Physics, math, engineering, AI

👉 HFSP explicitly promotes non-traditional collaborations

🧠 5. Novel Combinations of Expertise

Successful teams:
- Have members who haven’t worked together before
Must show:
- Complementary expertise
- Synergy

👉 “New collaborations” score higher than existing ones

🧪 6. No Requirement for Preliminary Data (Unique Feature)

HFSP:
- Does NOT require preliminary data
Focus is on:
- Idea quality, not prior results

👉 This enables:

Truly high-risk proposals

👩‍🔬 7. Investigator Creativity & Track Record

Reviewers look for:
- Creative thinkers
- Strong scientific background
Not necessarily:
- Established seniority

👉 Intellectual boldness matters more than CV prestige

🌍 8. Global Scientific Impact (Long-Term Focus)

Projects should:
- Advance fundamental understanding of life systems
Not required:
- Immediate clinical or commercial outcomes

👉 Long-term scientific breakthroughs are prioritized

🔬 9. Clear, Compelling Research Question

Must address:
- A fundamental biological problem
Should:
- Remove a major barrier in the field

👉 Mechanistic depth + conceptual clarity are essential

📑 10. Strong Letter of Intent (LOI) Strategy

Two-stage process:
1. LOI (highly competitive filter)
2. Full proposal

👉 Only a small fraction of LOIs advance

📊 Summary: Key Predictors (Ranked)

Highest impact factors:

High-risk, frontier basic science
Breakthrough innovation
International collaboration

Moderate predictors:
4. Interdisciplinary approach
5. Novel team composition
6. Scientific creativity

Supporting factors:
7. Clear research question
8. Global impact
9. LOI strength

💡 Insider Insight

Compared to other major funders:

Human Frontier Science Program is:
👉 the most “risk-tolerant” major funder
👉 strongly favors ideas over data

👉 Winning formula:
Bold idea + unconventional team + interdisciplinary approach

✔️ What wins:

Radical, paradigm-shifting ideas
Cross-disciplinary teams (e.g., physicist + biologist)
Novel collaborations

❌ What struggles:

Incremental research
Single-discipline biology
Overly safe or conventional proposals

Eligibility Requirements

HFSP encourages inclusion, diversity, equity, and accessibility (see our Shared Values Statement), and welcomes applicants independent of gender, origin, cultural background, or age. There is one application round per year for the HFSP postdoctoral fellowships.

In one year, each applicant may submit only one Letter of Intent for an HFSP postdoctoral fellowship (LongTerm Fellowship or Cross-Disciplinary Fellowship) and must propose a change in country AND a change in research topic. Unsuccessful applicants may reapply in subsequent years, provided they still meet all eligibility requirements.

Please note that each host supervisor may only endorse ONE applicant per year.

An HFSP postdoctoral fellowship may only be held once
