Gavin Sun (孙国栋)

I’m a PhD student at the Northwestern Polytechnical University, advised by Prof. Yuchao Dai.

My research focuses on 4D Reconstruction & Generation and Spatial Intelligence. I am particularly interested in understanding dynamic scenes and building coherent spatio-temporal representations of the physical world. My current work explores how tracking, geometric structure, and generative priors can be integrated to achieve robust and scalable 4D representations.
