I am a theoretical physicist with active experimental expertise, working at the interface of particle physics, cosmology, astrophysics and emerging experimental technologies. My research connects fundamental theory with experimental and observational tests, spanning dark matter, black holes, neutrinos, multi-messenger astronomy, gravitational waves, early-Universe physics, tests of fundamental symmetries, quantum sensing, large-scale detectors and precision measurement systems.
I play active roles in international experimental collaborations including Super-Kamiokande, Hyper-Kamiokande and also dark matter experiments.
Previously, I held appointments as Kavli Fellow at the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU), the University of Tokyo, and as Postdoctoral Scholar at University of California, Los Angeles (UCLA). I received my Ph.D. in experimental particle physics at the University of California, Irvine, where I analyzed Super-Kamiokande data and set leading limits on nucleon decay.
