Chenhao Wang

I am a Postdoctoral Researcher at Tongji University. I received my Ph.D. from The Chinese University of Hong Kong, Shenzhen, under the supervision of Pin Gao. Before that, I received my M.S. from the School of Management at Xi'an Jiaotong University, where I was advised by Yao Wang, and my B.S. in Mathematics from the same university.

My research interests lie in revenue management, with a focus on choice models and assortment optimization. I am particularly interested in building tractable models and efficient algorithms for large-scale assortment, pricing, and inventory decisions, and in bridging optimization theory with data-driven and machine learning methods.

My work has appeared in Management Science and Production and Operations Management, and has received several best-paper awards.
