Dear Colleague Letter: Research Collaboration Opportunity in Europe for NSF Recipients

Funding Agency:
National Science Foundation

February 2, 2024

Dear Colleagues:

To further scientific and technological cooperation between the United States and the European Community, the National Science Foundation (NSF) and the European Research Council (ERC) signed an Implementation Arrangement on October 29, 2019, to enable U.S.-based scientists and engineers with active NSF awards, particularly those early in their careers, to pursue research collaboration with European colleagues supported through EU-funded ERC grants.

Connecting researchers with complementary strengths and shared interests promotes scientific progress in solving some of the world's most challenging problems. This international research opportunity is mutually beneficial to the U.S. participants and their hosts through cooperative activities during research visits and by establishing international research partnerships to enrich future research activities in the U.S. and Europe.

Under the Implementation Arrangement, the ERC Executive Agency (ERCEA) identifies ERC-funded research groups who wish to host NSF recipients for research visits of up to one year within their ERC funding.

This letter invites current NSF recipients to submit supplemental funding requests for research visits to any identified, appropriate ERC-funded European research group. NSF particularly encourages requests from NSF funded researchers who are early in their careers or who are still actively building their careers. Further, the letter gives instructions on how to submit supplemental funding requests and other relevant policies and requirements.

Research visits will be funded as supplements to active NSF awards. PIs and fellowship recipients must consult with the cognizant NSF Program Director of the original award or Fellowship prior to submitting a supplemental funding request.

Requests must be received at NSF at least 3 months prior to the proposed visit, but no later than May 17, 2024, for consideration using Fiscal Year 2024 funds.
