Courses I have taught and/or am teaching. These courses and their resources are available through Sakai.
My research interests fall in the diverse area of discrete mathematics and theoretical computer science. In particular, my work focuses upon graph theory, algorithmic game theory, algorithms and discrete optimization.

Prospective Graduate Students
Normally, all full-time graduate students (both domestic and international) will be offered competitive financial support consisting of a graduate fellowship, a teaching assistantship, plus a research stipend from a Graduate Faculty supervisor. Complete application instructions and application components are outlined here.
