About Me

I am currently a sophomore in Electrical Engineering at the ZJU-UIUC Institute of Zhejiang University. I am an incoming research intern at the Hong Kong University of Science and Technology, advised by Professor Yinghao Xu. Before that, I was a research assistant at the CVNext Lab, ZJU-UIUC Institute, advised by Professor Gaoang Wang.

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.

I welcome any collaboration or discussion, whether with seniors or peers. I am also happy to discuss potential research fit and collaboration opportunities. Please feel free to reach out to me via email or wechat. 🤝

Research Interests

My research focuses on understanding and modeling the dynamic 3D world. Current interests include:

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.

Personality

🏓 I have a great passion for sports, especially table tennis, fitness and running. I am a member of the IZJU table tennis team and I particularly enjoy the spin-pushing playing style.
📷 I also have a strong fondness for photography. I like to capture some human landscapes and a corner of the city.
🎵 At the same time, I really like music. Currently, I am deeply obsessed with R&B and Chinese folk music.
📚 Finally, I really like reading. From philosophy and economics to online novels, I am very enthusiastic about all of them.
