Sy-David Friedman (born May 23, 1953 in Chicago) is an American and Austrian mathematician and a professor of mathematics at the University of Vienna and the director of the Kurt Gödel Research Center for Mathematical Logic. His main research interest lies in mathematical logic, in particular in set theory and recursion theory.

Contents

Friedman is the brother of Ilene Friedman and the brother of mathematician Harvey Friedman.

Biography

He studied at Northwestern University and, from 1970, at the Massachusetts Institute of Technology. He received his Ph.D. in 1976 from MIT (his thesis Recursion on Inadmissible Ordinals was written under the supervision of Gerald E. Sacks).

In 1979 Sy Friedman accepted a position at MIT, and in 1990 he became a full professor there. Since 1999 he has been a professor of mathematical logic at the University of Vienna. He is a Fellow of Collegium Invisibile.
