Keisuke Yoshihara after a race in Hawaii

I am an Assistant Professor of Physics at the University of Hawaii at Mānoa. I work on collider experiments (SuperKEKB/Belle II) to search for physics beyond the Standard Model. Previously, I was a member of the ATLAS experiment at CERN.

My group also develops detector and readout systems, including low-latency AI/ML on hardware.
