Topology

The Topology program administered by the National Science Foundation (NSF) supports fundamental research in a broad range of topology subfields, including algebraic topology, differential topology, geometric topology, and general topology and continua theory. Specific focus areas include chromatic, equivariant, motivic, and stable or unstable homotopy; homology and cohomology theories; bordism and K-theory; topological manifolds; knots and links; transformation groups; topological quantum field theories; contact and symplectic structures; and infinity and model categories. The program also supports research in topological data analysis, offering a robust platform for the advancement of theoretical and applied mathematics. The NSF is an independent federal agency established by Congress in 1950 to promote the progress of science. The Topology program is managed by the Division of Mathematical Sciences (DMS) within the Directorate for Mathematical and Physical Sciences (MPS). As a federal funder, NSF’s mandate includes ensuring that funded research aligns with national scientific priorities and policies, including the implementation of government-wide regulations such as the revised 2 CFR and recent executive orders. This program offers funding opportunities for both research and conferences. Conference proposals can cover events such as workshops, summer or winter schools, and similar gatherings. These proposals should be submitted using the “Conference” or “Travel” proposal type in research.gov and adhere to specific submission windows. Proposals with budgets under $50,000 must be submitted at least six months before the event, while proposals exceeding $50,000 must be submitted at least eight months prior. Submissions must comply with the NSF Proposal & Award Policies & Procedures Guide (PAPPG) applicable at the time of submission. Eligibility for this program is open to a broad range of institutions and organizations. While the solicitation does not explicitly list eligible entity types, NSF programs typically allow applications from U.S.-based academic institutions, nonprofit organizations, for-profit entities under certain conditions, and government research units. The geographic scope of the program is nationwide, consistent with NSF’s overarching mission to fund research that benefits the entire U.S. scientific community. The next full proposal target date for the Topology program is November 4, 2025. This date recurs annually, specifically on the first Tuesday in November. The program is not rolling but is recurring, providing regular opportunities for interested applicants to prepare and submit proposals. Applicants are expected to adhere strictly to PAPPG guidance and ensure compliance with all submission requirements. Contact for the program includes four program directors within MPS/DMS: Swatee Naik (snaik@nsf.gov, 703-292-4876), Eriko Hironaka (ehironak@nsf.gov, 703-292-7041), Qun Li (qli@nsf.gov, 703-292-7465), and Paulo M. Lima Filho (plimafil@nsf.gov, 703-292-7972). All inquiries and proposals should be directed through the appropriate platforms and with close attention to eligibility, timelines, and proposal format.
