The FNR and SNF 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 SNF as part of their Call) 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 SNF, Luxembourg participants are required to submit an INTER application within 7 days after the joint proposal’s submission at the Lead Agency.

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



The SNF 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).


  • The PI applying to the SNF must start the submission process no later than 1 day before the deadline, by 14:00 CET.
  • Documents required by the FNR (INTER Budget, INTER Budget Details; INTER Project plan) must be submitted with the main application to the SNF by 14:00 on the day of the call deadline.
  • The Luxembourg based PI must submit an INTER application to the FNR, including the application submitted to the SNF (as pdf) along with the FNR INTER documents no later than 7 days after the SNF deadline.
  • Applications to the FNR must be submitted through the FNR’s Online Grant Management System.


The Lead Agency will evaluate and select the proposals, in compliance with international standards, and propose a funding decision on behalf of both organisations. The Lead Agency will make use of the standard review procedures used in the respective funding programme to which the proposals are submitted.

To be recommended for funding, a proposal must be ranked among the top 20 % in the respective funding programme (funding threshold). A higher funding threshold might be acceptable, if the Luxembourg researchers have teamed with groups from Germany (DFG) and/or Switzerland (SNSF).
