To further scientific and technological cooperation between the European Community and the United States, an Implementing Arrangement was signed on July 13,2012 to enable U.S. scientists and engineers with NSF-funded CAREER awards and Postdoctoral Research Fellowships to pursue research collaboration with European colleagues supported through EU-funded European Research Council (ERC) grants. Under the Arrangement, the ERC Executive Agency (ERCEA) identifies ERC-funded research groups who wish to host NSF Postdoctoral Research Fellows for research visits of up to one year within their ERC funding. This is the final year of the program. ERCEA has provided a list of ERC-funded principal investigators and research teams interested in hosting NSF Postdoctoral Fellows. NSF Fellows should request this list via email from email@example.com, and then communicate directly with ERC PIs to as certain areas of mutual interest and research goals for a visit. Fellows may then submit their requests directly to their NSF Program Officers. If approved by NSF, the request is forwarded to ERCEA for review and for making arrangements with the ERC-funded project. The European hosts will provide funding to support in-country living expenses during the visits. NSF will provide travel funds to and from Europe. The application deadline is April 20, 2018.
