Our group focuses on the investigation of electronic structures of quantum materials using angle-resolved photoemission spectroscopy (ARPES). The research topics include topological quantum materials, strongly correlated electronic materials, and low-dimensional materials. We also devote into developing advanced ARPES techniques with resolutions of spatial, spin, and non-equilibrium dynamics.
