I am an Associate Professor in the Department of Mathematics at Columbia University. I completed my Ph.D at Princeton University in 2018. My advisor was Professor Richard Taylor. Before that, I was an undergraduate at Peking University.
I am interested in algebraic number theory, especially p-adic aspects of the Langlands program.
