about me

Hi there! My name is Shu Fay [舒斐] and I’m a Ph.D. candidate in Chemical Physics at Columbia University, advised by David Reichman. My research interests lie at the intersection of condensed matter physics and theoretical chemistry, where I seek to understand emergent phenomena in condensed matter by developing and applying electronic structure methods mature in the field of quantum chemistry. Currently, my research focuses on the strongly-correlated“Correlation” refers to effects that arise from interactions between particles ignored by single-particle (e.g. “mean-field”) approximations; the strongly-correlated regime is where these interactions dominate. electronic states discovered in moiré heterostructures, particularly the so-called “generalized Wigner crystal states” in bilayer transition metal dichalcogenides.

Prior to Columbia, I graduated with a B.S. in Physics from Caltech, where I worked on method development for electronic structure calculations with Garnet Chan and quantum algorithms for quantum chemistry with Peter Love and John Preskill.

I’m also an avid runner and can often be found on my n-th loop of Central ParkCounter-clockwise, of course. .
