About Me

I am currently working as a assistant professor at the Chinese University of Hong Kong, Shenzhen (CUHK-SZ).

Research Interests: Reinforcement Learning (RL) and the related topics, including, Inverse Constrained RL, Model-based RL, Interpretable RL, Agent Evaluation and Embedding. I have also studied applications on Natural Language Process (NLP), Sports analytic and Autonomous Driving.

Working Experience and Education: I have worked as a postdoctoral fellow at the University of Waterloo and Vector Institute with Prof. Pascal Poupart. I received my Ph.D. degree at the School of Computing Science, Simon Fraser University under the supervision of Prof. Oliver Schulte. I have finished a research internships at Cognitive Computing Lab, Baidu Research (supervised by Prof. Ping Li). I received my Bachelor degree at the School of Computing Science and Engineering, South China University of Technology.
