Biography

I received my Ph.D. in Industrial Engineering from Texas A&M University in 2007 and my B.Tech. in Mechanical Engineering from the Indian Institute of Technology Madras in 2002. My research focuses on graph-powered analytics: modeling and solving optimization problems in which graphs and networks play a central role. My core expertise is in discrete optimization, graph algorithms, and integer programming, and my work spans applications in healthcare analytics, computational biology, crop analytics, social network analysis, and network interdiction. My current research centers on temporal graphs and graph signatures, and on optimization methods for discovering high-risk patterns in healthcare data. I am also interested in classical areas of operations research such as transportation logistics, production-inventory planning, and scheduling.

My research has been sponsored by National Science Foundation, Department of Energy, Air Force Office of Scientific Research, Office of Naval Research, and industry partners. Publications coauthored with my students and other collaborators have appeared in Operations Research, INFORMS Journal on Computing, INFORMS Journal on Optimization, and INFORMS Journal on Applied Analytics, among others. I serve on the editorial boards of Networks (Wiley) and Journal of Global Optimization (Springer).
