Bio

I am an assistant professor in the Department of Physics and Astronomy at Johns Hopkins University. My research focuses on theoretical condensed matter physics, with an emphasis on strongly correlated quantum systems.

Before joining JHU in 2022, I was a postdoctoral scholar at Harvard University (2019–2021) working with Ashvin Vishwanath and Subir Sachdev. I received my Ph.D. in Physics from MIT (2019) under the supervision of T. Senthil, and my B.Sc. in Physics from Peking University (2014).

Research Interests

Cuprate & Nickelate Superconductors

New theoretical frameworks for high-temperature superconductors, pseudogap metals, and quantum critical phenomena in strongly correlated materials.

Moiré Superlattices and 2D Materials

Strongly correlated and topological phases in moiré flat-band systems, including correlated insulators, unconventional superconductivity, quantum anomalous Hall effects, and Mott physics.

Fractional Phases

Fractionalization and emergent gauge fields in quantum spin liquids, quantum Hall multilayers, and deconfined quantum critical points.

Numerical Methods

DMRG, variational Monte Carlo, DMFT, and neural network quantum states for controlled studies of strongly correlated systems.
