I have been mainly involved in the research and development of medical devices.In particular, I have been involved in the development of medical devices related to particle therapy and real time target monitoring devices such as RGPT(real-time image gated radiotherapy system).(Example in Japanese) https://www.amed.go.jp/news/release_20201113-01.html At the same time, I have been involved in cancer care as a radiation oncologist, operating a proton beam case registry in Japan, and planning and conducting clinical trials.I have resigned from my previous position, Hokkaido University and now have been working at Osaka Unierseity as Professor of Medical Science.I am looking for a job in a new field of research, development and education if there is a chance, at out side of Japan.
