I am an assistant professor in the Mathematics Department at the United States Naval Academy.

At USNA, I teach a variety of courses in the mathematics department, ranging from calculus to simulation modeling. My research interests include cooperative game theory, mechanism design, combinatorial optimization, and applications of these areas to scheduling, network interdiction, and logistics.

I received a PhD in operations research from MIT in June 2008, under the supervision of Professor Andreas Schulz. In June 2002, I received an AB and SM in applied mathematics from Harvard University.

My mathematical genealogy can be found here. My Erdös number is 3 (P. Erdös → P. Hell → M. Mastrolilli).
