About

I am a Ph.D. candidate in Computer Science and Technology at Chongqing University of Posts and Telecommunications, advised by Prof. Xinbo Gao (高新波) and Associate Prof. Jiaxu Leng (冷佳旭). My current research focuses on Active Anomaly Understanding, with interests in video anomaly understanding, active visual reasoning, and multimodal large language models.

My recent work studies how vision-language agents can actively acquire evidence, reason over anomalous events, and understand challenging real-world scenarios such as aerial anomalies, low-light surveillance, and autonomous-driving corner cases.
