## Eligibility & scope

Bilateral Lead Agency project funding between SNSF and FWO (Flanders) for joint research projects; applicant must partner with a researcher at a listed Flemish university or institution. Belgian researchers must start the approved project in January of the following year; project duration must not exceed 48 months and be the same in both countries.

## Summary

Weave is a bilateral funding scheme between the SNSF and Luxembourg's FNR that supports joint research projects by a Swiss and a Luxembourg-based researcher, using a Lead Agency model where one funder carries out the full evaluation. Projects run up to 48 months if SNSF is Lead Agency or up to 36 months if FNR leads, and on the Luxembourg side proposals must fall under FNR's CORE thematic research programme. The call has no fixed annual round, SNSF accepts Weave/Lead Agency proposals continuously against its regular 1 April and 1 October deadlines.

## Who should apply

- Researchers based at Swiss institutions partnering with a researcher in Luxembourg
- Joint applicant teams submitting one coordinated proposal for single evaluation
- Luxembourg-side research falling within FNR's CORE thematic programme
- Applicants holding at most one other simultaneous project funding grant

## Key dates

- SNSF Lead Agency deadlines are 1 April and 1 October, submitted continuously with no annual cutoff
- FNR's 2027 deadline has not yet been set
- Duration is up to 48 months under SNSF Lead Agency or up to 36 months under FNR Lead Agency

## Tips for applicants

- Decide upfront which funder acts as Lead Agency, this fixes both the evaluation body and the maximum project duration you can request.
- Confirm the Luxembourg partner's project fits FNR's CORE thematic programme before drafting, since Weave on the FNR side is restricted to that scheme.
- If proposing in a non-English language for eligible humanities or social science topics, secure prior agreement from the Lead Agency before submission.
