- Ph. D., University of Geneva, 1992
His research is in the area of experimental particle, nuclear, and astroparticle physics, particularly on quark flavor physics by rare decays of hadrons, CP violation, neutrino oscillation, the study of nuclear states of matter and cosmic ray physics. He is currently the co-spokesman of the Fermilab E907 experiment. He is also author of the book The Elusive Neutrino, editor of the Conference series on Hyperon, Charm and Beauty Hadrons, and has over 180 referred articles in physics research. Current experiments include MIPP, NOvA and cosmic-ray R&D.
