About me

Dr. Hairi (pronounced "Hi-Ree") is a tenure-track Assistant Professor in the Department of Computer Science at the University of Wisconsin-Whitewater (UWW). He received his B.E. and M.E. degrees from Tsinghua University, and his Ph.D. in Electrical and Computer Engineering from Arizona State University, advised by Prof. Lei Ying. Prior to joining UWW, he was a postdoctoral researcher at The Ohio State University and AI-EDGE Institute, advised by Prof. Kevin Liu.

His research interests lie in multi-agent reinforcement learning, stochastic modeling and analysis, machine learning, multi-agent systems, and applications of AI in real-world systems.
