Daniel Ramras, Ph.D.



Ph.D. - Stanford University, 2007

B.A. in Mathematics, Cornell University, 2002


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.
