## About Me

**Welcome!**

I am a fifth-year PhD student in mathematics at Columbia University studying under Professor Michael Harris.

My main research interests are in number theory, arithmetic geometry, and automorphic forms. These include:

- Special values of L-functions
- Rational points on algebraic varieties
- Representation theory of reductive groups
- Arithmetic dynamics
