My research focuses on solving some of the outstanding mysteries in modern physics, from the matter/antimatter asymmetry through potential charge-parity violation in neutrino oscillation experiments T2K, Super-Kamiokande, and Hyper-Kamiokande, to unveiling the invisible dark matter in our universe with previous direct dark matter searches, XENON100 and XENON1T. Throughout my career in these collaborations, I led a wide range of efforts designing and constructing instruments critical for the experiments, as well as developing analysis and machine learning algorithms to minimize systematics to an unprecedented level.
