I am a Ritt Assistant Professor at Columbia University.
Previously, I completed my PhD in Mathematics at Northwestern University in Spring 2021 under the guidance of Ben Weinkove.
My research interests are in complex geometry and partial differential equations, specifically, on complex geometric flows and constant scalar curvature problems.
