Sathamangalam Ranga Iyengar Srinivasa Varadhan is an Indian American mathematician and statistician, born in 1940, known for fundamental contributions to probability theory and in particular for creating a unified theory of large deviations. Since 1963 he has worked at the Courant Institute of Mathematical Sciences at New York University, where he began as a postdoctoral fellow from 1963 to 1966, strongly recommended by Monroe Donsker. There he met Daniel Stroock, who became a close colleague and co-author. Varadhan, whom everyone calls Raghu, came to the United States from his native India in the fall of 1963.
