My research interest is to address questions about the nature of the universe from a viewpoint of experimental particle and astroparticle physics. Especially, I have a great curiosity about how the universe is created and of what it is comprised. Dark matter is an essential subject to pursue the composition of the universe and I am working on the direct detection of dark matter in the XMASS and XENONnT experiments. I am also working on neutrino physics such as supernova neutrino and double electron capture using the dark matter detectors.
