I am a Chu Assistant Professor of Applied Mathematics at Columbia University.

Previously, I was a PhD student at the University of Washington, advised by Randall J. LeVeque and Gunther Uhlmann.

Research Interests

My interests are in the numerical analysis of partial differential equations (PDEs) and inverse problems
