Biography
After receiving a Doctor of Science degree in materials science and engineering from Tokyo Institute of Technology (Tokyo Tech) in March 2018, I spent one and a half years as a Postdoctoral Fellow at Photon Factory (PF), Institute of Materials Structure Science (IMSS), High Energy Accelerator Research Organization (KEK). Then I returned to Tokyo Tech as a Specially Appointed Assistant Professor in October 2019.
Expectations for WRHI
I am looking forward to conducting collaborative research in materials science with researchers of various interests and experiences.
