Keisuke Harigaya
Assistant Professor
Department of Physics and the College
Keisuke Harigaya’s research provides theoretical explanations to open problems in the standard model of particle physics and cosmology. The problems in which he is interested include anomalously small parameters in the standard model, the identity of dark matter, and the origin of the excess of matter over antimatter. His theories predict signals that can be tested by various experiments such as particle colliders, direct detection of dark matter, and observations of galaxies.
His research has been published in Physical Review Letters, Journal of High Energy Physics, and Physical Review D, and has been cited by numerous other media outlets such as Quanta Magazine, Science News, and Tähdet ja avaruus (Star and Space).
Harigaya holds BS, MS, and PhD degrees from the University of Tokyo, all in physics. He completed postdoctoral fellowships at the Institute for Cosmic Ray Research of the University of Tokyo; the University of California, Berkeley; Lawrence Berkeley National Laboratory; the Institute for Advanced Study; and the European Organization for Nuclear Research (CERN).
