What the grant funds

The U.S. National Science Foundation Directorate for Mathematical and Physical Sciences (NSF MPS) supports multiple research programs at the frontiers of discovery in theoretical and applied mathematical sciences. Programs include: Algebra and Number Theory Analysis Applied Mathematics Combinatorics Computational Mathematics Foundations Geometric Analysis Mathematical Biology Probability Statistics Topology Mathematical Sciences Focused Research Groups Mathematical Sciences Infrastructure Program Mathematical Sciences Research Training Groups NSF anticipates a portfolio of awards for these programs with a range of budgets, durations and scopes. Program budgets, number of awards, award sizes and durations are subject to the availability of funds. NSF MPS is particularly interested in intellectually ambitious and potentially transformative foundational research. Proposals need not promise a near-term product, deployment, or commercial outcome, nor need they address later-stage development to be competitive.
