About Me

I am a sophomore majoring in Electrical Engineering at Zhejiang University’s ZJU-UIUC Institute. Currently, I am a Research Intern at RobbyAnt, mentored by Prof. Yinghao Xu. Previously, I worked as a research assistant at the CVNext Lab in the ZJU-UIUC Institute under the supervision of Prof. Gaoang Wang.

My research focuses on understanding and modeling the dynamic 3D world, including streaming 4D perception and reconstruction of dynamic scenes, long-context vision models for learning from continuous visual experience, and 3D representation learning for geometry, motion, and generation.
