Feng Chen

I am currently a Ph.D. candidate at the College of Computing and Data Science (CCDS), Nanyang Technological University (NTU), supervised by Prof. Bo An.

Previously, I obtained my M.Sc. and B.S. degrees from the School of Artificial Intelligence at Nanjing University, where I was advised by Prof. Zong-Zhang Zhang.

My research interests broadly include Reinforcement Learning, Multi-Agent Systems, and Large Language Model Agents.
