I am a Benjamin Peirce Assistant Professor in the Mathematics Department 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-1506652.

Here's my CV last updated September 18, 2017
