I am an Assistant Professor in the Mathematics Department at MIT. Formerly I was a Benjamin Peirce Assistant Professor at Harvard University.
I completed my Ph.D. under the supervision of D.H. Phong at Columbia University in New York City.
Before studying at Columbia, I studied mathematics at the University of British Columbia in Vancouver, B.C.,
where I worked with Malabika Pramanik.
I do research in geometry and analysis. I am particularly interested in geometric flows, and applications of algebraic geometry to analysis, and vice versa.
My research is partially supported by NSF grant DMS-1810924, NSF CAREER grant DMS-1944952, and an Alfred P. Sloan Fellowship.
Here's my CV last updated January 12, 2022.
