Noam Levi

I'm a theoretical physicist currently working as a AI4Science Postdoctoral Fellow at EPFL. My research focuses on employing concepts from random matrix theory, statistical physics, and field theory to better understand deep learning algorithms, as well as integrating AI into fundamental physics research.

Previously:

PhD Student - Theoretical Particle Physics at Tel Aviv University, under Prof. Tomer Volansky.
Visiting researcher at IAS, Princeton.
