Research

My research focuses on the geometry and topology of representation spaces, using techniques from algebraic topology, K-theory, algebraic geometry, and differential geometry. I’m also interested in large-scale geometry and its applications to assembly maps in algebraic K-theory.

Education

Ph.D. – Stanford University, 2007

B.A. in Mathematics, Cornell University, 2002
