Personal Information

Hello, I am Hongyao Tang. I just finished my Ph.D. in Deep Reinforcement Learning (DRL) Lab, Tianjin University advised by Jianye Hao and Zhaopeng Meng. I will be a Postdoctoral researcher in Robotics and Embodied AI Lab (REAL) at the Université de Montréal and Mila, and will work with Professor Glen Berseth, starting from Fall 2023.

My research interests lie in unveiling the co-learning dynamics of representation and Reinforcement Learning (RL) function approximation and realizing new approaches/paradigms for efficient, performant and generalizable RL. Currently, my research focus is Self-supervised Representation Learning in DRL and Off-policy RL. I am also interested in Meta RL, MARL, Offline RL and Foundation Models for Decision Making.

I have experiences in applying DRL in practical problems like Electronic Design Automation (EDA), Drug Discovery, Online Games and etc. I am very willing to contribute to addressing real-world problems.
