Chenhao Wang

I am a Postdoctoral Researcher in Tongji University, I got my Ph.D. degree from The Chinese University of Hong Kong, Shenzhen, under the supervision of Pin Gao. I received my Master degree in the School of Management from Xi'an Jiaotong University, China, where I was very fortunate to be advised by Yao Wang.  Prior to that, I received my Bachelor degree in Mathematics from Xi'an Jiaotong University.

My research interests lie in revenue management, especially in Choice Model and  Assortment Optimization.
