I am currently an Assistant Professor in the Department of Mathematics at the University of Pennsylvania. I received my PhD from the University of Texas and then spent several years at Stanford with an NSF postdoctoral fellowship. I live with my wife, Lori Lejeune, and two cats in Philadelphia.

Research Interests:

I am primarily interested in the topology of low dimensional manifolds and its relation with geometry and dynamics. Please take a look at my research proposal in postscript or pdf format and my vita in postscript or pdf format.
