He is a condensed-matter physics experimentalist and his research interests include high-temperature superconductivity, strongly correlated electron systems, low-dimensional electron systems, and quantum magnetism.

Our research is focused on various "Quantum Phases of Matter", including unconventional superconductivity, hidden order phase, and quantum spin liquid. We are also studying the anomalous properties associated with the quantum critical point, which is a zero-temperature boundary between two different phases.
