I am a fifth-year PhD student at Harvard. I am advised by Mihnea Popa. Before, I was an undergraduate at Columbia University.
I am interested in algebraic geometry, especially deformation theory and moduli problems, singularities, Hodge theory, and derived categories.
My research is supported by a Simons Dissertation Fellowship.
I will be on the academic job market in Fall 2026.
