The National Science Foundation (NSF) is offering Postdoctoral Research Fellowships in Biology (PRFB) aimed at recent doctoral graduates for research and training in specific areas supported by the Directorate for Biological Sciences. Eligible applicants must submit proposals individually, identifying a sponsoring scientist and an appropriate host institution, and must meet specific criteria, including U.S. citizenship and a focus on research that aligns with NSF's goals. These fellowships are designed to foster independence in early-career scientists, encouraging them to pursue significant scientific inquiries while collaborating with experienced mentors. The estimated total funding for this program is $17 million, with individual awards starting at $270,000, and proposals are due by November 7, 2024.
