This was followed by the SLD experiment at the only linear electron-positron collider to study the properties of the Z0 weak boson with a focus on the decays to strange particles tagged with the intricate Cherenkov Ring-Imaging Detector (CRID) subsystem. Working on the Beijing Spectrometer (BES) experiment at the Beijng Electron Position Collider in China I met my future CSU colleague Walter Toki. In the BaBar collaboration at SLAC, I helped to design and build the novel Detector of Internally Reflected Cherenkov light (DIRC) that was part of an important measurement of Charged-Parity (CP) violation in B meson decays. CP violation may explain the matter-antimatter asymmetry of the universe and has been a central theme of my research for nearly 20 years. Along the way and I contributed to studies of particle identification in detectors at a future International Linear Collider, which is under consideration for construction in Japan.
