Yu Chen (陈宇) I am currently a 1st-year Ph.D. student at the University of Chinese Academy of Sciences (UCAS) and the Institute of Automation, Chinese Academy of Sciences (CASIA), advised by Prof. Changsheng Xu in the National Laboratory of Pattern Recognition (NLPR). My research focuses on multimodal agent post-training and video understanding, with the goal of enabling agents to perceive the world and make complex decisions more like humans. My perspective is shaped by both research training and hands-on industry experience. I believe impactful research should not only push the boundaries of knowledge, but also solve real problems with scalable, simple, and robust methods.
