Max 2 simultaneous SNSF project grants; topics must be clearly distinct. Non-English submissions possible only in certain humanities/social sciences disciplines with prior agency agreement.

## Summary

The Weave Lead Agency call funds bilateral research projects between Switzerland (SNSF) and the Wallonia-Brussels Federation of Belgium (F.R.S.-FNRS) for up to 48 months. Both Swiss and Belgian teams must participate, submit in parallel, and run identical project timelines; Belgian applicants must be based at one of six eligible universities (UCLouvain, ULB, ULiège, UMons, UNamur, or USL-B). This is an annual call open across all disciplines, with applications in languages other than English possible in some humanities and social sciences fields by prior agreement.

## Who should apply

- Researchers based at Swiss institutions (SNSF-eligible) and one of six eligible Belgian universities in Wallonia-Brussels
- Research teams planning genuine international collaboration with synchronized timelines
- Projects in any discipline (humanities, social sciences, natural sciences, engineering eligible)
- Applicants willing to navigate dual submission and coordination with partner agency

## Key dates

- SNSF deadline: 1 October 2026 (copy must be submitted to SNSF within 7 days of F.R.S.-FNRS submission)
- F.R.S.-FNRS deadline passed: 7 July 2026 (next round annual)
- Project duration: up to 48 months, synchronized start date in both countries

## Tips for applicants

- If leading through F.R.S.-FNRS (Belgium), submit to your national agency first, then copy to SNSF within 7 days; coordination between Swiss and Belgian partners is essential to meet both deadlines.
- Belgian applicants must verify their institution is one of the six eligible universities; if outside Wallonia-Brussels or not on the list, you cannot be the Belgian lead.
- Non-English language proposals in humanities and social sciences require written agreement from all agencies before submission; contact SNSF and F.R.S.-FNRS in advance to avoid delays.
