I am a theoretical condensed matter physicist working on emergent quantum phenomena in systems with many degrees of freedom. My research is driven by the principle of universality: that complex physical behavior, across vastly different systems, can often be understood through simple and robust effective descriptions. I aim to uncover such universal structures in quantum materials and engineered hybrid systems.

My research focuses on topological superconductivity, Majorana bound states, and odd-frequency pairing, as well as transport in low-dimensional quantum systems. I am particularly interested in identifying robust and experimentally relevant signatures of topological phases in realistic platforms, including semiconductor–superconductor heterostructures and fractional quantum Hall–superconductor junctions. More broadly, my work explores the interplay between topology, interactions, and nonequilibrium dynamics, with the goal of developing unified theoretical frameworks for emergent quantum matter.

I am especially fascinated by topological order and the emergence of exotic quasiparticles such as anyons, which lie beyond the conventional fermion–boson paradigm and connect deep mathematical structures to experimentally realizable systems. These ideas not only deepen our understanding of quantum matter but also provide promising routes toward fault-tolerant quantum computation.

I received my undergraduate, master’s, and PhD degrees from Nagoya University, where I worked in the group of Yukio Tanaka on superconductivity and topological quantum systems. Following a brief appointment as a Project Assistant Professor at Nagoya University, I joined Kyushu University in 2026, where I am currently a Project Assistant Professor in the group of Kentaro Nomura.
