I am an Associate Professor of Decision Sciences at the School of Business, The George Washington University. Prior to joining GWU, I was an Associate Professor in the Department of Analytics & Operations at NUS Business School, National University of Singapore. I received my Ph.D. in Operations Research from University of California, Berkeley and B.Eng. in Logistics Management and Engineering from The Hong Kong University of Science and Technology. My current research involves using optimization and machine learning tools to address problems in smart city operations (e.g., vehicle sharing, electric vehicle, energy system, and last-mile delivery) and supply chain management. This line of research has been recognized with the M&SOM Journal Best Paper Award, Transportation Science & Logistics (TSL) Best Paper Award, and ENRE Best Publication Award in Energy from INFORMS.
