## Eligibility & scope

Bilateral Swiss–Flemish collaborative research projects under the Weave/Lead Agency framework, assigned to FWO's Junior and Senior Research Projects programme. Swiss applicants must be based at a Swiss institution; Flemish partners must be at one of the listed FWO-eligible universities. Max 2 simultaneous SNSF project grants; topics must be clearly distinct. Project start in January following approval.

## Summary

The Weave Lead Agency scheme funds bilateral collaborative research projects between Swiss and Flemish institutions, with up to CHF/EUR available over four years. The call targets researchers in all disciplines who are ready to establish or extend cross-border partnerships, with a Swiss-based principal investigator leading the application through the SNSF and a Flemish co-applicant at an eligible FWO university. This is the only funding route for Swiss, Flanders collaboration under the SNSF Weave initiative.

## Who should apply

- Swiss researchers based at a Swiss institution (principal investigator role)
- Flemish researchers at an FWO-eligible university in Belgium
- Researchers in any discipline with a clearly defined bilateral research plan
- Applicants not simultaneously holding more than one other SNSF project grant

## Key dates

- Deadline 1 April 2027 (submissions open in April only)
- Single-stage simultaneous submission to SNSF (Lead Agency) and FWO; FWO submission must be copied to SNSF within 7 days
- Up to 48 months project duration; start date January following approval

## Tips for applicants

- Coordinate your submission timing carefully: applications must go to FWO first, then copied to SNSF via mySNF within 7 days, missing the 7-day window can stall or block your SNSF review.
- Ensure both the Swiss PI and Flemish co-applicant are formally committed before submission; joint drafting of the research plan strengthens the bilateral angle and reviewers check for genuine co-design.
- Verify that your Flemish partner institution is on the FWO-eligible university list; miscategorization can cause rejection at triage.
