Biography

Currently I am a graduate student of School of Artificial Intelligence in Nanjing University and a member of LAMDA Group, led by professor Zhi-Hua Zhou.

I received my B.Eng. degree in Automation from School of Management and Engineering, Nanjing University in June 2021. In September 2021, I was admitted to pursue a M.Sc. degree in Nanjing University, under the supervision of Associate Professor Zongzhang Zhang.

Research Interests

I am interested in theoretically justified algorithms and real-world applications of Reinforcement Learning (RL). When RL ventures beyond game environments, numerous challenging problems may arise, such as the absence of suitable reward functions, the lack of high-fidelity simulators, and the continually evolving environments, to name a few. To deal with the above issues, I am currenly working on

Inspired by the impressive success of ChatGPT, I am also interested in decision making via Large Language Models (LLMs). Please feel free to drop an email if you would like to discuss or collaborate with me.
