Jeremy Kahn

Jeremy Adam Kahn (born 1969) is an American mathematician. He works on hyperbolic geometry, Riemann surfaces and complex dynamics.
Kahn grew up in New York City. He studied mathematics for his bachelor's degree at Harvard University then received his Ph.D. from the University of California, Berkeley in 1995 under Curtis McMullen with thesis Holomorphic removability of quadratic polynomial Julia sets. As a postdoc he was at the University of Toronto. He was assistant professor at Caltech and at the State University of New York at Stony Brook. After that he worked for the investment firm Highbridge Capital Management as an analyst in financial mathematics. Since 2011 he has been a professor at Brown University.
In 2012 he with Vladimir Markovic received the Clay Research Award for their research on hyperbolic geometry, specifically, for their result on immersions into a closed hyperbolic 3-manifold (proof of the surface subgroup conjecture) and for their proof of the Ehrenpreis conjecture.
On the basis of his success in the Putnam competition he became in 1988 a Putnam Fellow. In 2014 he was an invited speaker at the International Congress of Mathematicians in Seoul and gave a talk The surface subgroup and the Ehrenpreis Conjectures.
