About

I am a theorist working on various aspects of quantum many-body physics. My research explores how collective behavior emerges in quantum systems and how methods inspired by quantum information and artificial intelligence can help us understand it.

I am currently a Sherman Fairchild Postdoctoral Scholar at the Walter Burke Institute for Theoretical Physics at Caltech. I received my Ph.D. in Physics from MIT in 2025, was a Graduate Fellow at the Kavli Institute for Theoretical Physics (KITP) in 2024, and received my undergraduate degree from Harvard in 2019.
