About Me

Who Am I?

Hi I'm Yuan Cao, currently a postdoc researcher and Junior Fellow at Harvard. I graduated from MIT in 2020 as PhD and joined Harvard in 2021. My current research is condensed-matter physics in 2-dimensional materials. I specialize on the study of 'twistronics' —— electronics in materials with a 'twist'.

My interests and specialties are quite diverse, spanning from physics, electronic engineering, nanotechnology, and computer science. I am also hobbyist in electronic hacking, astrophotography, and violin.

Moire twistronics

"Twistronics" in 2D materials

Twisted 2D materials exhibits a long-range moire pattern that hosts a number of intriguing properties, among them superconductivity and quantum anomalous Hall effect. I study the physics in these systems through quantum electronic transport experiments.


Microstructures for manipulation

I am interested in micromechanical engineering in 2D materials, to explore further degree of freedoms and to reveal unprecedented phenomena in them.
