Research Institute for Radiation Biology and Medicine, Assistant Professor
I'm origibally from Osaka. My major was particle physics in a graduate school. Now I've just started doing researches related to radiation protection because I want to get involved in lives of people and sciety directly. I want to work not only for research but also for risk comunication.
