I am a graduating PhD student at Columbia University studying mathematics under Professor Michael Harris.

I will be an NSF Postdoctoral Fellow at MIT starting in fall 2023.

My main research interests are in number theory, automorphic representations,
and Diophantine geometry. Areas that are particularly motivating to me include:

• Special values of L-functions

• Rational, torsion, and periodic points

• Restriction & multiplicity-one problems
