My teaching interests are management science, operations research, statistics, optimization models and algorithms, and spreadsheet modeling and simulation. My research interests are in combinatorial optimization, integer programming, polyhedral theory, and polynomial-time algorithms. My current research focus is on Chvatal inequalities, Chvatal rank, and polynomial solvability of integer programming problems. I received the Jay N. Ross Young Faculty Scholar Award (2005), John and Mary Willis Young Faculty Award (2008) and Krannert Faculty Fellow (2008) at Krannert School of Management. I was selected as University Faculty Scholar (2014-2019) at Purdue. I am a member of the Institute for Operations Research and the Management Sciences (INFORMS), Mathematical Optimization Society (MOS) and the Society for Industrial and Applied Mathematics (SIAM).
