I am a 1st-year Ph.D. student from Tsinghua University, advised by Prof. Yebin Liu. Previously, I received my bachlor's degree at Nankai University. My research spans embodied AI, robotics, 3D vision and video generation. I am particularly interested in exploring action representations and how they can be more effectively integrated with vision inputs, with a recent focus on studying World Action Models for embodied AI systems.
