Fan Zhang

Hong Kong University of Science and Technology

I am currently a postdoctoral associate in the Department of Mathematics at Hong Kong University of Science and Technology, jointly advised by Prof. Can Yang and Prof. Jianping Gan. I completed my Ph.D. at the University of Electronic Science and Technology of China, under the supervision of Prof. Wenyu Chen and Prof. Hong Qu. I received my Bachelor degree at the University of Electronic Science and Technology of China, advised by Prof. Hancong Duan.

My research interests include:

  1. AI for Scientific Discovery: discover scientific concept from noisy observational data, with application in Ocean and life science.
  2. Reinforcement Learning: offline reinforcement learning, multi-agent reinforcement learning.
