Institute Professor Isadore Singer, a world-renowned mathematician known for his work covering a broad spectrum of geometry, analysis, and algebra, was MIT’s James R. Killian, Jr. Faculty Achievement Award winner for 2005–2006. “His work is fundamental in differential geometry, topology, in function and operator algebras and in partial differential equations,” said Professor Marcus Thompson, chair of the Killian Award Committee.
