I am a Postdoctoral Scholar in the Department of Computer Science and Engineering at the University of California, Santa Cruz, where I work with Prof. Yuyin Zhou and Prof. Cihang Xie in the VLAA Lab. My research focuses on visual content generation, world models, and AI agents.
I received my Ph.D. degree in Information and Communication Engineering from the University of Science and Technology of China in March 2026, under the supervision of Prof. Yongdong Zhang and Prof. Hongtao Xie at the National Engineering Laboratory for Brain-inspired Intelligence Technology and Application (NEL-BITA) and the Intelligent Multimedia Content Computing Laboratory (IMCC). Prior to that, I obtained my bachelor’s degree in Automation from the University of Science and Technology of China.
