## Summary

The Weave Lead Agency call (SNSF, FNR) funds bilateral research projects between Switzerland and Luxembourg, with the SNSF acting as lead agency and the FNR participating through its CORE thematic programme. Swiss applicants must establish consortia with at least one Luxembourg partner, with projects running up to 48 months under SNSF or up to 36 months under FNR leadership. Swiss researchers may hold at most two concurrent SNSF project grants, with one required to be a Weave or Lead Agency project.

## Who should apply

- Swiss researchers hosted at a recognised Swiss research institution
- Research teams establishing bilateral consortia with at least one Luxembourg partner
- Projects aligned with FNR CORE thematic research priorities
- Researchers managing no more than two concurrent SNSF project grants

## Key dates

- Deadline 1 April 2027
- Up to 48 months (SNSF lead) or up to 36 months (FNR lead)
- Annual call rounds in spring and autumn (1 April and 1 October)

## Tips for applicants

- If submitting to FNR first, copy the application to SNSF via mySNF within 7 days of FNR submission, missing this window triggers rejection by the Swiss agency.
- Verify your project aligns with FNR CORE thematic areas early; the Luxembourg side's eligibility gates the entire bilateral project.
- Non-English proposals (humanities and social sciences only) require prior written agreement from both agencies before submission.
