Bio


I'm a PhD student at AIVC Lab, UCLA Department of Mathematics, advised by Prof. Chenfanfu Jiang. I received my M.S. degree from the Department of Computer Science, the State University of New York at Stony Brook, and my B.S. degree from the Department of Mathematical Sciences, Tsinghua University (China).

My current research focuses on 3D generation and reconstruction, with a particular emphasis on utilizing physics-based simulation: On one hand, simulation serves as a tool to introduce dynamics into 3D scenes reconstructed from real-world data; On the other hand, I am exploring the integration of physics as a regularization within generation and reconstruction pipelines.

I am expecting to graduate in March 2025 and am actively seeking full-time opportunities. Please feel free to contact me.
