My teaching interests are management science, operations research, statistics, optimization models and algorithms, and spreadsheet modeling and simulation. My research interests are combinatorial optimization, integer programming, polyhedral theory, graph
theory and network flows. My current research focus is on the study of Chvatal closure, clutters, matchings and traveling salesman problem. 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).
