About
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
- Uncertainty quantification (UQ) concerning nonlinear hyperbolic systems of conservation laws, via reduced order models (ROMs).
- Target applications are geophysical problems: probabilistic tsunami hazard assessment (PTHA) and statistical tsunami source inversion.
- Inverse anisotropic conductivity from power densities in dimension three.
