I am an Assistant Professor at the Department of Computational and Data Sciences at George Mason University. Prior to joining George Mason University, I was an Assistant Professor at the Department of Industrial Engineering at the University of Pittsburgh. Before, I was a lecturer in the Operations Research and Statistics Group at the MIT Sloan School of Management and a postdoctoral research associate in Operations Research at MIT. I hold a PhD degree in Applied Mathematics from MIT.
My overarching career goal is to leverage operations research, data analytics, and artificial intelligence to serve society. Specifically, my research program aims to achieve this goal by 1) advancing the underlying mathematical and computational techniques, such as data-driven, robust, and distributionally robust optimization, and their interface with machine learning to enable the design of data-driven models suitable for a wide range of applications.; and 2) applying these methods to real-world complex decision-making problems. I have worked on various applications, including kidney exchange, epidemic modeling and analysis, rare-event modeling and prediction, supply chain operations, WHO-EPI vaccine distribution, and online resource allocation. I have assembled a diverse research team of six PhD students working toward these research directions. My research program has received support from the Office of Naval Research, NSF, and DARPA.
