The FNR and FWO have both signed Weave, a bottom-up, cross-European initiative developed by European research funders to support excellent collaborative research projects across borders. Weave has been signed by 12 funding agencies from 11 European countries.

From 2021 onwards, both agencies can act as Lead Agency, i.e. collaborative proposals could be submitted either to the FWO as part of the channel for regular FWO research projects for fundamental research or to the FNR CORE call. The applicants can freely choose the Lead Agency among the agencies they are eligible for funding. If the collaborative proposal is submitted to the FWO, Luxembourg participants are required to submit an INTER application within 7 days after the joint proposal’s submission at the Lead Agency. (see “Weave info for Luxembourg based researchers”).

Weave allows for the funding of bilateral (i.e. FWO + FNR) or trilateral research consortia (i.e. FWO + FNR + a third funder). Due to a stepwise implementation of Weave by the signatories, not all collaborations are already eligible in 2021. Please check the Weave-website for more details.

The FNR and FWO have an agreement in place to support bilateral research projects between scientists based in Belgium and Luxembourg. All research proposals must explicitly demonstrate the scientific added value of to the complementary cross-border research activities.

The FWO is the lead agency in this agreement and will manage all bilateral FNR / FWO projects.

Funding is limited to research projects with a maximum duration of 4 years.



The FWO or the FNR can act as lead-agency. Applicants can freely choose where to submit a collaborative project but must follow the rules of the respective call (also in view of project duration).
