The U.S. National Science Foundation's Partnerships for Research Innovation in the Mathematical Sciences program aims to enhance partnerships between minority-serving institutions and DMS-supported Mathematical Sciences Research Institutes. The activity seeks to boost the participation of members of groups underrepresented in the mathematical sciences through their increased involvement in research programs at the institutes. Key aspects of this opportunity include: • Eligible applicants are minority-serving institutions of higher education in the United States that award degrees in the mathematical sciences and are not currently classified as Doctoral Universities with "Very High Research Activity" (R1 institutions). • Eligible partners include DMS-supported Mathematical Sciences Research Institutes. • The Principal Investigator must hold a faculty appointment at the MSI submitting the proposal. • Funding of any partnering DMS-supported Mathematical Sciences Research Institutes, if applicable, must be requested via subawards.
