Our people

My research field is neutrino physics and astroparticle physics. I have been involved in the Super-Kamiokande experiment for many years, focusing on solar and supernova neutrino observations as well as low-energy event analyses. In particular, I have played a central role in the search for the diffuse supernova neutrino background (DSNB) enabled by the gadolinium upgrade of Super-Kamiokande (SK-Gd), and in improving the real-time alert system for galactic supernovae.

I currently serve as the spokesperson of the Super-Kamiokande Collaboration, while also contributing to the development of the research and operational framework bridging Super-Kamiokande and Hyper-Kamiokande. In addition, I am actively involved in detector R&D for next-generation low-energy physics, including searches for dark matter and neutrinoless double beta decay.
