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.
Funding: I am grateful to be supported by an NSF CAREER grant DMS-2143754 and NSF grants DMS-1855684, DMS-2133806. I am also a consultant for an ONR MURI on Foundations of Deep Learning.
Please see my CV for more information.

News
- Together with Jacob Foster (Sociology, UCLA), Jessica Flack (Collective Computation Group, Santa Fe Institute), Josh Tenenbaum (Brain and Cognitive Science, MIT), Max Kleiman-Weiner (Common Sense Machines), Orit Peleg (Computer Science, Colorado), Patrick Shafto (Rutgers/IAS, Mathematics), Pranab Das (Physics, Elon), Tom Griffiths (AI & Cognitive Science, Princeton) I am organizing a semester-long program at IPAM in Fall 2024 on the Mathematics of Intelligences. This program will bring together researchers working on learning in both biological and artifical settings with the goal of identifying and making progress on mathemcial questions related to learning and intelligence. Here is the website.
- I am speaking at a two-day program in mid-August on the theoretical aspects of Machine Learning at the Center for Brains, Minds, and Machines Summer School in Woods Hole, MA.
- I am speaking at a workshop on statistical physics and machine learning in beautiful Cargese, Corsica, which runs July 31 - August 12.
- I will be a plenary speaker at the 2023 IAIFI Summer Workshop on Theoretical Physics and ML in August 2023. This workshop will immediately follow the 2023 IAIFI Summer School.
- I am organizing in late June the 2023 Princeton Deep Learning Theory Summer School. Approximately 80 students from around the world will attend to hear courses by Cengiz Pehlevan (Harvard), Arthur Jacot (NYU), Francesca Mignacco (Princeton), Philippe Rigollet (MIT), Jeffrey Pennington (Google), and Ben Adlam (Google).
