NSF is The National Science Foundation
The NSF is a United States government agency that supports fundamental research and education in all the non-medical fields of science and engineering. With an annual budget of about US$7.0 billion (fiscal year 2012), the NSF funds approximately 24% of all federally supported basic research conducted by the United States colleges and universities. In some fields, such as mathematics, computer science, economics, and the social sciences, the NSF is the major source of federal backing.
The NSFs director and deputy director are appointed by the President of the United States, and confirmed by the United States Senate, whereas the 24 presidentially appointed members of the National Science Board (NSB) do not require Senate confirmation. The current NSF director, confirmed in March 2014, is astronomer France A. Córdova, former president of Purdue University.
