Son of Vera Rubin. Between 1997 and 2006, Karl Rubin was a professor at Stanford, and before that worked at Ohio State University between 1987 and 1999. His research interest is in elliptic curves. He was the first mathematician (1986) to show that some elliptic curves over the rationals have finite Tate-Shafarevich groups. tI is widely believed that these groups are always finite. Rubin graduated from Princeton University in 1976, and obtained his Ph.D. from Harvard in 1981. His thesis advisor was Andrew Wiles. He was a Putnam Fellow in 1974, and a Sloan Research Fellow in 1985. In 1988, Rubin received a National Science Foundation Presidential Young Investigator award, and in 1992 won the American Mathematical Society Cole Prize in number theory. In 2012 he became a fellow of the American Mathematical Society. Selected honors and awards: Humboldt-Forschungspreis (Humboldt Foundation Research Award) - 1999; Guggenheim Fellowship - 1994; AMS Cole Prize in Number Theory - 1992; NSF Presidential Young Investigator Award - 1988; Editorial positions: Journal of the American Mathematical Society, Managing Editor, 2009-2013; Algebra & Number Theory 2007-2013; Journal f u r die reine und angewandte Mathematik 1994-2001; Compositio Mathematica 1993-1998; Journal of Number Theory 1987-1999.
