Steven Hurder

Steven Edmond Hurder is an American mathematician specializing in foliation theory, differential topology, smooth ergodic theory, rigidity of group actions and spectral and index theory of operators. Hurder presently holds the title of Professor Emeritus at University of Illinois Chicago. Hurder was named as an inaugural fellow of the American Mathematical Society in 2013.

Education
Hurder received his PhD in 1980 at University of Illinois Urbana-Champaign. His advisor was Franz W. Kamber, and the title of his dissertation was Dual Homotopy Invariants of G-Foliations.
