About Me

I am an undergraduate in Electrical Engineering at the ZJU-UIUC Joint Institute of Zhejiang University (B.S. 2024-2028). My research focuses on understanding and modeling the dynamic 3D world, with current interests in streaming 4D perception, long-context vision models, and 3D representation learning. Since July 2025, I have been working with Prof. Gaoang Wang in the CVNext Lab.

I am currently interested in test-time training as a form of memory for long-context visual understanding.

Research Interests

Streaming 4D perception and reconstruction of dynamic scenes
Long-context vision models for learning from continuous visual experience
3D representation learning for geometry, motion, and generation
