I started working in the Hsieh group at Caltech as a postdoctoral scholar in September 2021, supported by the JSPS overseas research fellowship. I received my Ph.D. in Physics from the University of Tokyo, Japan, in March 2021. For my doctoral thesis, I studied the electronic structures of novel topological insulators and surface Rashba systems, using laser-based ARPES as well as synchrotron-based ARPES. 

Research Interests

I am interested in novel quantum phenomena in solid state physics induced by the spin-orbit coupling such as

  • Topological phases in a matter
  • Rashba-type spin splitting at the surface/interface

I investigate these phenomena by laser- or synchrotron-based (spin- and) angle-resolved photoelectron spectroscopy.
