After he received his PhD in science from the Science University of Tokyo, Japan, in 2001, he moved to Osaka University to join an experimental particle physics group for muon physics. He also holds an assistant professorship at RCNP, and is the leader of the MuSIC muon facility of RCNP. His research field is muon related science, and includes the development of intense muon beams, the wide range of applications of muons, and the search for charged lepton flavor violation.
