## Who should apply

- Swiss researchers seeking a Flemish collaborator at eligible Belgian institutions (KU Leuven, UGent, VUB, UAntwerp, and others)

- Research groups with a clearly defined bilateral project scope
- Applicants not exceeding 2 simultaneous SNSF project grants

## Tips for applicants

- Synchronise timelines carefully: FWO and SNSF submissions are simultaneous, and the SNSF copy must reach mySNF within 7 days of FWO submission.
- Ensure the project scope is clearly bilateral and distinct from any other SNSF grants either applicant holds; reviewers flag overlap across concurrent applications.
- Identify your Flemish partner institution early, not all Belgian universities are eligible under FWO (KU Leuven, UGent, VUB, UAntwerp are confirmed).
