About me.

I am an Assistant Professor in the Department of Mathematics and Statistics at Smith College.  Before coming to Smith, I was a postdoctoral fellow at the Max Planck Institute for Mathematics in Bonn, Germany, and a Hans Rademacher Instructor at the University of Pennsylvania.  My research is in geometric and low-dimensional topology.
