National Science Foundation

Funds National Science Foundation, the United States agency supporting broad competitive science and engineering programs.

The National Science Foundation (NSF) is the primary U.S. federal agency for basic and applied research across science and engineering outside medical sciences. Established in 1950, it supports about 11,000 competitive awards a year and reaches roughly 350,000 researchers, entrepreneurs, students, and teachers across about 1,900 institutions. FY2025 appropriations were $8.826 billion, and NSF is responsible for about a quarter of federal support for basic research at U.S. colleges and universities.

NSF funds grants, fellowships, instrumentation, centers, workforce programs, and innovation routes that stretch from graduate training to startup translation. The named programs here include CAREER, GRFP, MRI, EPSCoR, REU, Engineering Research Centers, NRT, NAIRR-OC, PFI, I-Corps, and NSF SBIR/STTR, with awards ranging from about $50,000 for I-Corps to $35 million for NAIRR-OC and $4 million for MRI. The portfolio also includes the SBIR/STTR and PFI family, which supports entrepreneurship and technology translation alongside the more traditional research and training lines.

NSF is strongest for proposals that combine strong science with broader impacts, workforce development, infrastructure, or a clear translation path. Its directorates span biology, computing, engineering, geosciences, mathematics and physical sciences, social and behavioral science, STEM education, and technology and innovation, so the right fit depends on the problem and the community it serves. The agency tends to reward clear intellectual merit, a well-defined project plan, and a credible institutional home.
