About me

I am a CS PhD student at UIUC, advised by Prof. Tong Zhang and Prof. Huan Zhang. Previously, I earned my bachelor’s and master’s degrees from the Department of Automation at Tsinghua University and CSE, HKUST. Currently, my research focuses on: Agents, Trustworthy LLMs/VLMs, and Deep reinforcement learning.

Prior to my PhD, I was fortunate to work closely with Prof. Chongjie Zhang (Washington University in St. Louis), Dr. Lei Han (Noitom Robotics, formerly Tencent AI Lab), and Prof. Meng Fang (University of Liverpool).

Hobbies

In my leisure time, I enjoy sports like running, table tennis, and swimming. During my time at Tsinghua University, I was an amateur long-distance runner. In 2019, I completed a half marathon (21.0975 km) in 1 h 30 min and a full marathon (42.195 km) in 3 h 36 min. However, since starting my PhD I haven’t had time for regular running training, so I’ve let it slide. Hopefully I’ll get a chance to update my record once I graduate🙂.
