Current state of research and teaching activities
My field is an experimental research for Particle Physics. I have been working on the Belle experiment which have been operating at the electron-positron storage ring at KEK since 1990's. I am now working on the Belle II experiment, an upgraded version of Belle experiment, and aiming for finding new physics phenomena beyond the standard model in particle physics. See URL: http://belle.kek.jp/ for more details.
