Profile I've been involved in a lot of experimental research on piping systems and other structures at National Research Institute of Earth Science and Disaster Resilience, and have started my carrier at Tokyo City University from 2021.
I have about 20 years' experience in experimental research activities on the seismic safety evaluation of light-water nuclear piping systems. Main interest of my research activities is on the beyond design condition, such as the seismic safety estimation of aged piping systems, or the ultimate behavior of piping systems under high inelastic region.

I'm a member of the Subcommittee on Seismic Design of Nuclear Power Plant in the Japan Electric Association since 2009, and the chief of the technical subcommittee of piping systems and equipment from 2018.
Research Field(Keyword & Summary)
