I'm an Assistant Professor in the Applied Mathematics and Statistics department at Johns Hopkins University. I obtained my PhD in the ACO program at Carnegie Mellon University, advised by Gerard Cornuejols.

My research interests lie in Optimization (with current emphasis on theoretical Integer Programming), Operations Research, Discrete and Combinatorial geometry, and Convex analysis.

Heard while eavesdropping on a mathematician: "These schemes are pointless"
