Biography

I am a third-year PhD student of TSAIL Group in the Department of Computer Science and Technology, Tsinghua University, advised by Prof. Jun Zhu and Prof. Hang Su. Previously, I received my B.S. degree from the Department of Automation of Tsinghua University in July, 2021. I spent a wonderful time at the Digital Media Lab in Tsinghua University, advised by Prof. Yebin Liu in the field of 3D vision and AIGC from Oct, 2018 to May, 2019. I had also been a research intern at Netease's Fuxi AI Lab and ByteDance's AI Lab respectively in 2021 and 2020.

Currently, my research interests lie primarily in the area of deep reinforcement learning and deep generative models. My lifelong goal is to build a scalable, impenetrable and adaptable decision-making engine that could relieve human from tedious tasks and elevate their work efficiency. My current progress includes being a core developer of Tianshou : A highly modularized deep reinforcement learning library , designing large-scale Online RL system for MOBA games (see Competitions below), and bridging the gap between RL algorithms and generative modeling methods for AIGC such as diffusion models.
