Michael Handel is an American mathematician known for his work in Geometric group theory. He is a Professor in the Department of Mathematics at Lehman College of The City University of New York and a Professor of Mathematics at The Graduate Center of The City University of New York.

Career[]

Michael Handel graduated with a B.A. in mathematics from Brandeis University in 1971.[1]  He received his Ph.D. from University of California, Berkeley in 1975 under the supervision of Robion Kirby.[2]  From 1975 to 1978, he was an instructor at Princeton University. He joined the faculty of Michigan State University as an Assistant Professor in 1978,[3]  and was promoted to Associate Professor in 1983.[4]  Handel was a visiting scholar at the Institute for Advanced Study from 1978 to 1979, and again from 1987 to 1988.[5]  In 1990, he joined the Mathematics Department at Lehman College.

Handel is best known for developing the Train track map method in Geometric group theory in collaboration with Mladen Bestvina in 1992.[6]  Bestvina, Feighn and Handel later proved that the group Out(Fn) satisfies the Tits alternative, settling a long-standing open problem.[7][8]
