Mathematical Sciences Postdoctoral Research Fellowships
Can you apply?
This grant is for recent Ph.D. recipients in mathematical sciences seeking postdoctoral research positions. Applicants must have earned or be about to earn a U.S. Ph.D. in mathematics, applied mathematics, statistics, or closely related fields within a recent timeframe (typically within the last several years). U.S. citizens, nationals, and permanent residents are eligible. The fellowship supports two to three years of postdoctoral research conducted at U.S. institutions. Applicants work closely with sponsoring scientists at host institutions to develop independent research programs. International travel for collaboration is permitted. The program aims to support researchers at the early stages of their careers as they transition to permanent academic or research positions.
Program description
The purpose of the Mathematical Sciences Postdoctoral Research Fellowships (MSPRF) is to support future leaders in mathematics and statistics by facilitating their participation in postdoctoral research environments thatwill have maximal impact on their future scientific development. There are two options for awardees: Research Fellowship and Research Instructorship. Awards will support research in areas of mathematics and statistics, including applications to other disciplines.

FAQ
Am I eligible if I have a Ph.D. from outside the United States?
Yes. You must hold a U.S. Ph.D. in mathematical sciences or a closely related field, regardless of where you received your previous education. International Ph.D.s are not eligible for this fellowship.
When is the application deadline?
The typical deadline is in October (October 21, 2026 for this cycle). Check the NSF website for any updates, as deadlines can shift. Applications must be submitted through NSF's FastLane or Research.gov system.
Can my postdoctoral research be conducted at an international institution?
No. The research must be conducted at a U.S. institution (university, national laboratory, or research center). However, international collaborations and travel are permitted during the fellowship.
How competitive is this fellowship?
This is a highly competitive fellowship. Success typically requires a strong research proposal, excellent letters of recommendation, and evidence of research potential. Applicants should demonstrate how their postdoctoral work will develop into an independent research program.
What is the typical funding amount?
The fellowship typically provides an annual stipend to support the fellow's salary, with some flexibility for research expenses and institutional support. Exact amounts vary by year and field; consult the current program solicitation for specific ranges.
💡 Tips for applicants
- Start early and work closely with your sponsoring scientist to develop a compelling, independent research proposal that builds on but extends beyond your Ph.D. work.
- Letters of recommendation are critical; secure commitments from Ph.D. advisors and respected colleagues who can speak to your research potential and readiness for independence.
- Clearly articulate how your postdoctoral research will transition you toward an independent research career; reviewers want to see your long-term research vision.
- Tailor your research plan to demonstrate how it fills a gap in mathematical sciences and why it requires the specific resources or environment of your host institution.
- Have your host institution's sponsored research office review your application early to ensure all institutional commitments and budget documentation are accurate and complete.
⚠️ Common mistakes
Applications often fail because the research proposal lacks sufficient independence from the sponsor's work—reviewers expect fellows to establish their own research directions. Another frequent issue is inadequate articulation of how the postdoctoral period will prepare the fellow for an independent research career, particularly in academic settings. Weak letters of recommendation, especially from sponsors who do not clearly address the applicant's readiness and potential, significantly hurt competitiveness.
