Zhaoyi Li

Welcome to My Homepage!

Hello! I'm Zhaoyi Li, courtesy name Nitan, a PhD student at MIT working in theoretical and mathematical physics, with an interest in the structure and dynamics of complex systems.

Bio

I graduated from Stanford University with a BS in Mathematics and a BSH in Physics, and am now pursuing a PhD at MIT in the Quanta Group under Prof. Isaac Chuang. I am also part of IAIFI.

My research explores theoretical frameworks connecting information and collective behavior in physical systems, with tools drawn from representation theory and statistical physics. For a comprehensive list of my publications, you can visit my Google Scholar or ORCID profiles.

For more in-depth reflections and discussions, the Qōan Blog features thoughts on topics such as mathematical physics, algorithms, and personal projects.
