I work on theoretical condensed matter physics, especially quantum matter with emergent gauge structures and holographic behavior.

I am an Assistant Professor in the Masaki Oshikawa group and Takashi Oka group at the Institute for Solid State Physics, The University of Tokyo.

My research is about unusual collective behavior in quantum matter. I am especially interested in places where condensed matter physics meets quantum information and high-energy theory.

Recent projects include dipole-octupole quantum spin ice, classical and quantum spin liquids, fracton phases, and machine-learning tools for frustrated magnets.

What I work on

Fundamental theory of frustrated matter

I use field-theory ideas to understand quantum spin liquids, emergent gauge fields, and topological constraints.

Quantum materials

I connect theoretical ideas to candidate pyrochlores, quantum spin ices, and related materials.

Computational tools

I use numerical and data-driven methods to connect theoretical predictions with experimental probes.
