I am a third-year Ph.D. student at the Chinese University of Hong Kong, advised by Prof. Pheng-Ann Heng and Prof. Chi-Wing Fu. Prior to my Ph.D. studies, I worked as an algorithm engineer at Tencent AI Lab, where I developed RL-based game agents and designed diverse reward strategies to encourage varied playstyles. I hold an M.Sc. in Big Data Technology from the Hong Kong University of Science and Technology and a B.Sc. (Hons) in Computer Science and Technology from Beijing Normal–Hong Kong Baptist University.

My research focuses on multimodal understanding, particularly exploring native active perception as reasoning to bridge the gap between passive audio-visual observation and active agentic decision-making.

Beyond academia, I am passionate about basketball, tennis, and regular gym workouts—sports define my mindset.
