Biography
I am an Assistant Professor in the Department of Management Sciences, College of Business, City University of Hong Kong. I obtained a Bachelor of Engineering degree from Tsinghua University and a Ph.D. degree in Management from the National University of Singapore. I was a postdoctoral research associate in the Area of Analytics & Operations at the Imperial College Business School.
My primary research involves developing models and designing algorithms for analytics under uncertainty with different levels of data availability as well as applications in business, economics, finance, and operations. I am also interested in how to compete or cooperate in joint activities such as resource allocation and risk management.
I am keen on developing packages for analytics under uncertainty and I have been actively working on the project "Robust Stochastic Optimization Made Easy (RSOME)" (MATLAB, Python).
