Biography
Ryohei (he/him/his) received his Bachelor of Science in Physics at Osaka University in 2014, Master’s degree of Science in Physics at the University of Tokyo in 2016, and Ph.D. degree of Science in Physics at the University of Tokyo in 2019. He worked as a Special Postdoctoral Researcher from 2019-2022 at RIKEN, Japan.
Education
- Ph.D. Apr. 2016 – Mar. 2019 Department of Physics, School of Science, The University of Tokyo, Tokyo, Japan
- M.Sc. Apr. 2014 – Mar. 2016 Department of Physics, School of Science, The University of Tokyo, Tokyo, Japan
- B.Sc. Apr. 2010 – Mar. 2014 Department of Physics, Faculty of Science, Osaka University, Osaka, Japan
Professional Experience
- Aug 2022-Jul 2024: Japan Society for the Promotion of Science (JSPS) Oversea Research Fellow
- Apr 2019- Jul 2022: RIKEN Special Postdoctoral Researcher (SPDR)
Research Interests
Ryohei has been working mainly on photoevaporation of protoplanetary disks by developing his radiation hydrodynamics code. Using the computational technique, he extended his research area to photoevaporation of molecular clouds and galactic minihalos. He also worked on an observational study of a protostar (L1527) using ALMA and VLA and a laboratory-experimental study of molecular line emissions at the previous institute (RIKEN). He has experienced skills in developing codes, applications, and data-analyzing tools.
