Yehua Wei

About Me Welcome to my website! I am an associate professor in the Decision Sciences area at the Fuqua School of Business. I obtained my Ph.D. in Operations Research Center (ORC) at MIT, and my undergraduate degree in Combinatorics and Optimization and Pure Math at University of Waterloo. Link to my CV is here. Research Interest My research interests span across multiple areas within operations research and operations management, including dynamic resource allocation, process flexibility, network design, vehicle routing, inventory systems, and queueing games. A recurrent theme of my work is developing a fundamental understanding of systems and policies designed to manage uncertainties. In my research, I have employed a variety of methodologies, including convex optimization, combinatorial optimization, robust optimization, stochastic networks, queueing theory, dynamic programming, game theory, and artificial intelligence.
