Ziyi Wang 王梓懿

I am a Ph.D. student in Computer Science and Technology at Peking University, advised by Prof. Mengyuan Liu and Prof. Hong Liu. My research focuses on Multimodal Large Language Models, Human Motion Perception and Generation, and Embodied AI.

Before that, I received my B.S. degree in Computer Science and Technology from Ocean University of China in 2024 (ranked top 1 out of 289 students).
