Biography

I am a PhD student at the UCLA AIVC Lab, advised by Prof. Chenfanfu Jiang and Prof. Demetri Terzopoulos. I obtained my M.S. degree in Computer Science from UCLA and my B.Eng. degree in Software Engineering from Shanghai Jiao Tong University. Prior to UCLA, I spent a gap year as a research intern in Bytedance AI Lab.

My current research interests focus on physics-based simulation and generative AI for digital content creation. I am particularly interested in developing models that are physically constrained and controllable for the generation of 2D, 3D, and 4D content.

Miscellaneous

I am a big fan of Japanese animes. Shinsekai yori (From the New World) is my GOAT. During my free time, I also enjoy fingerstyle guitar playing. Daniel Padim and Kotaro Oshio are two of my favorite guitarists.
