Zhengyuan Zhou

  I'm currently an assistant professor in the Department of Technology, Operations, and Statistics at Stern School of Business, New York University. Before joining NYU Stern, I obtained my Ph.D. in the Information System Laboratory in Department of Electrical Engineering at Stanford University in summer 2019, advised by Professor Nick Bambos and Professor Peter Glynn . During the year 2019-2020, I was gratefully supported by the IBM Goldstine fellowship and also a visiting assistant professor at NYU Stern.

My research interests lie at the intersection of machine learning, stochastic control and optimization. I'm broadly interested in developing sample-efficient and computationally efficient policy learning algorithms for data-driven decision making problems. Some of my recent research projects include distributionally robust policy learning, learning to adaptively bid in first-price auctions, efficient policy learning with limited adaptation, offline policy learning using adaptively collected data and next-generation RL.
