## Summary

The HFSP Long-Term Fellowship funds postdoctoral researchers to conduct three-year frontier basic-science projects in a country other than their PhD origin, with a PhD conferred after September 2023. The fellowship is restricted to interdisciplinary, non-clinical life sciences and requires full-time commitment at non-profit institutions. This is a highly competitive, internationally mobile postdoctoral award emphasizing transformative, cross-disciplinary research.

## Who should apply

- Postdoctoral researchers with PhD conferred after September 2023
- Applicants from any nationality moving to a country of PhD nationality
- Researchers proposing frontier, interdisciplinary basic-science projects
- Candidates committing 100% full-time effort at non-profit host institutions
- Researchers who have not spent more than 12 months in the host country

## Key dates

- Full Proposal deadline 24 September 2026 (by invitation only; LOI deadline passed 12 May 2026)
- Two-stage: Letter of Intent screening, then full-proposal submission from shortlist
- Three-year fellowship duration

## Tips for applicants

- The mandatory country-switching rule is gating, you cannot work in your nationality country or PhD country, and cannot have resided >12 months in the host country before applying; check this early.
- HFSP prioritises frontier interdisciplinary research; avoid incremental project extensions; emphasise conceptual novelty and cross-disciplinary bridges explicitly.
- This is a by-invitation-only full-proposal call; the LOI is highly competitive and must signal ambition and feasibility to pass screening.
