01 Description of Research

I have been studying elementary particle neutrinos in underground in Kamioka, Hida city, Gifu prefecture, by using detectors called Kamiokande and Super-Kamiokande. In recent years, I have been involved in building a detector called KAGRA for gravitational-wave astronomy also in underground in Kamioka. KAGRA has started the observation in February 2020. By using this detector, we are planning to observe various phenomena in the Universe which can only be studied with gravitational waves.
