Short Bio

From 2020.06 - 2023.06,I am a master's student in the Institute of Automation, Chinese Academy of Sciences, supervised by Prof. Xinwen HOU. From 2021.09 - 2022.09, I worked as a visiting student in the School of Computing and Information Systems, Singapore Management University, where I was honored to work closely with Prof. David Lo, Zhou Yang and Jieke Shi. In 2020.06, I obtained my Bachelor's degree from the School of Information Engineering, China University of Geosciences, Beijing, where I worked with Prof. Yunyun Niu. Currently, I focus on the following research topics: reinforcement learning security; offline reinforcement learning; convex duality in reinforcement learning; adversarial policy; generative model; variational inference.
