About

I am a postdoctoral fellow at the Institut des Hautes Études Scientifiques (IHES). I was an NSF Postdoctoral Fellow and Instructor at MIT from 2023 to 2026, and I received my PhD from Columbia University under the supervision of Michael Harris in May 2023.

My main research interests are in number theory, algebraic geometry, and representation theory, such as the interplay between:

• Special values of L-functions
• Rational, torsion, and periodic points
• Representations of finite & p-adic groups
• Cluster algebras

I am also a trained sommelier and co-editor of the James Beard-nominated cookbook Made Here by the NYC volunteer organization Send Chinatown Love.
