The National Science Foundation (NSF) is offering the Mathematical and Physical Sciences Ascending Faculty Catalyst Awards (MPS-AFCA) to support successful MPS-Ascending Postdoctoral Research Fellows as they transition into tenure-track faculty positions at Institutions of Higher Education (IHE) in various scientific disciplines. This grant aims to provide additional resources for research and broadening participation activities, enhancing the fellows' contributions and leadership in their fields, particularly within the divisions of Astronomical Sciences, Chemistry, Materials Research, Mathematical Sciences, and Physics. With an estimated total program funding of $7.5 million and an expected 25 awards, the program invites proposals from eligible applicants, specifically prior recipients of MPS-Ascend Postdoc Fellowships, with no cost-sharing requirement. Interested applicants should contact the NSF grants.gov support at grantsgovsupport@nsf.gov for assistance and can find more information at the NSF publication link provided.
