I'm an Associate Professor at the Computer Science Department of the University of Wisconsin-Milwaukee . Prior to coming here in 2002, I was an Industrial Postdoctoral Associate at the Institute for Mathematics and its Applications (IMA), collaborating with research scientists at Telcordia Technologies. I received my Ph.D. from the Mathematical Sciences Department at Johns Hopkins University. My thesis advisor was Lenore Cowen.
Here is a picture of our little ones, Madison and Nolan.

My general interests lie at the intersection of computer science and discrete mathematics. They typically fall under one of the following categories: Algorithm Design, Combinatorial Optimization, Combinatorics, and Graph Theory.
