About Me

I am an Assistant Professor at Princeton ORFE working on deep learning, probability, and spectral asymptotics. Prior to Princeton, I was an Assistant Professor in Mathematics at Texas A&M, an NSF Postdoc at MIT Math, and a PhD student in Math at Northwestern, where I was supervised by Steve Zelditch.

I am also an advisor and member of the technical staff at Foundry, an incredible AI/computing startup that seeks to orchestrate the world’s compute.

Funding: I am grateful to be supported by a 2024 Sloan Fellowship in Mathematics, NSF CAREER grant DMS-2143754 and NSF grants DMS-1855684, DMS-2133806.

Please see my CV for more information.
