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.

Midwest Theory Day for Spring, 2009 was held here at UWM.

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