Harvard University, Ph.D. in Physics, 1989 (advisor: Prof. Carlo Rubbia)
University of California, Berkeley, B.A. in Physics, summa cum laude, 1982
My research is in accelerator-based experimental particle physics. I have worked on the study of proton-proton collisions, proton-antiproton collisions and electron-positron collisions. My interests have spanned precision tests of the electroweak model; flavor physics studies, particularly the physics of hadrons containing b quarks; and the search the Higgs boson and particles not contained in the standard model of particle physics. I have been a member of the following experimental collaborations: ATLAS (CERN Large Hadron Collider) 2007 to present; CDF (Fermilab Tevatron) 1993 to present; OPAL (CERN LEP Collider) 1989-1993; UA1 (CERN SPS Collider) 1984-1989; R608 (CERN Intersecting Storage Rings) 1982-1983
