About Me

I am a postdoctoral researcher at Columbia University, working with David Reichman. I completed my Ph.D. in Physics and M.S. in CSEM from UT Austin in 2025, advised by Feliciano Giustino. Before that, I studied at Wuhan University and worked with Xi Dai at HKUST.

My research lies at the intersection of condensed matter physics, materials science, and chemistry. I combine many-body theory with first-principles methods to understand and predict real materials, with particular interest in how electronic excitations couple to the lattice and spin degrees of freedom.
