About me

I am an Assistant Professor in the Department of Statistics and Data Science at Yale University. My research interests lie broadly at the intersection of statistics, machine learning, probability theory, and computer science. My goal is to develop theoretical foundations for modern machine learning paradigms, with a particular focus on deep learning.

Previously, I was a Research Assistant Professor at Toyota Technological Institute at Chicago for a year. I received my PhD in Statistics from Stanford University where I was advised by Prof. Andrea Montanari. Prior to my PhD, I was a student at Ecole Normale Superieure de Paris where I obtained a B.Sc. in Mathematics and a M.Sc. in Theoretical Physics.

Prospective students

I am looking for highly-motivated Ph.D. students to join my group. If you are interested in working with me, please email me a short description of your research interests and a CV! Note that if you are not at Yale, you should first apply to our PhD program and mention my name.

I will be recruiting postdoctoral scholars starting Summer 2025! Please email me a a short description of your research, a CV, and a list of your publications.

I am also happy to host undergraduate/graduate visitors.
