My research program is the Belle II experiment and Belle experiment at KEK in Tsukuba, JAPAN.

These experiments study CP Symmetry Violation (Matter-Antimatter Asymmetry) in the B Meson System and search for signatures of Beyond the Standard Model (BSM) physics. Belle provided experimental confirmation of Kobayashi and Maskawa's explanation of CP violation in the weak interaction and was recognized in the citation for the 2008 Nobel prize in Physics, which was awarded to Kobayashi, Maskawa and Nambu. I was Belle II spokesperson from 2013 to 2019, during the construction and commissioning phase of the experiment. Belle II started physics running with nanobeams in spring 2019 and to date has integrated 429 fb^-1 of data, which is being analyzed. Run 2 will start in February 2024. Currently I chair the US Belle II Executive Board and also chair the Belle II Publications Committee (2021-2025).

I teach undergraduate physics courses and supervise graduate students and postdocs. I am searching for new graduate students. I participated in the Snowmass process in 2022 and am preparing for the next decade of Belle II electron-positron research and for the upgrades during LS2 (Long Shutdown 2).
