I am Gordon McKay Professor of Electrical Engineering and of Applied Mathematics at the Harvard John A. Paulson School of Engineering and Applied Sciences, and since 2024 I have also held the title of Harvard College Professor.

My research focuses on the mathematical foundations of AI, data science, and signal processing, with an emphasis on randomness and structure in high-dimensional systems. I use probabilistic methods to study the collective behavior of large systems of interacting components and to characterize the fundamental limits of their performance. This work aims to bring mathematical clarity to core challenges in modern machine learning and information processing, contributing to a deeper understanding of these rapidly developing fields.

During the 2024–26 academic years, I am serving as Director of Graduate Studies for Applied Mathematics. I am also a faculty affiliate of the Harvard Data Science Initiative and the Center of Mathematical Sciences and Applications (CMSA).
