About Me

Hi there, I’m Yuchen! I’m a CS PhD student at Georgia Tech, advised by Prof. Bo Zhu. Before that, I obtained my BSc in CS from Peking University. I was fortunate to work with Prof. Baoquan Chen during my undergraduate research.

My research interest lies in Computational Modeling. My main focus is to develop high-performance and high-fidelity numerical algorithms to solve computational challenges associated with various kinds of physical systems.
