Introduction

I am an assistant professor in Industrial and Systems Engineering at University of Minnesota, Twin Cities. I received my Ph.D. in Management Science and Engineering at Stanford University in 2012. My research interest is in optimization, stochastic modeling and its application in operations management. Specifically, I am interested in revenue management and pricing problems in which firms have to make pricing decisions facing customer choice behavior, competition and demand uncertainty. In addition, I also work on internet economics, prediction markets and sensor network localization problems.
