Ph.D. in Computer Science

University of British Columbia

Welcome to you, and also welcome to me!

I’m a CS Ph.D. student at the University of British Columbia, advised by Prof. Peter Yichen Chen.

My research develops AI foundation models for protein structure, interaction, and dynamics, combining geometric deep learning, physics-grounded priors, and large-scale molecular dynamics data. I am particularly interested in (i) physically valid biomolecular generation, (ii) scalable protein–protein interaction discovery, and (iii) Transformer-based neural simulators that learn protein conformational dynamics from MD trajectories. More broadly, I work on neural surrogate models for physical dynamics, at the intersection of computer graphics, scientific computing, and machine learning.

I graduated from Shanghai Jiao Tong University with a B.S. degree in Physics and a minor in Computer Science.

Before starting my Ph.D., I interned at SJTU DA Lab, where I worked with Prof. Xubo Yang and Ph.D. student Hui Wang, and also collaborated remotely with Bo Zhu. I also worked at DMCV with Prof. Ran Yi. From September 2024 to December 2024, I was an exchange student at the University of Toronto, where I worked with Zhecheng and Prof. Eitan Grinspun.
