Jonathan Dorfan received his B.Sc. from the University of Cape Town in 1969 and his Ph.D. from the University of California at Irvine in 1976. He is currently Professor of Physics and Associate Director at the Stanford Linear Accelerator Center, Stanford University. As a postdoctoral fellow, he participated in the construction of the MARK II detector and the MARK II program at SPEAR, where his research included elucidating the role of the weak current in t decays. He was the Spokesman for the MARK II at PEP where he concentrated his efforts on hadronic decays of the t and on jet physics. He was the Co-Spokesman for the MARK II SLC program, both for the upgrade of the detector and the scientific program. This pioneering effort, using electron-positron collisions to study Z boson decays, made important contributions to physics and techniques despite the rather small data set. Most notable was the first statistically significant result limiting the number of neutrino species to less than four.

Jonathan's current physics interests center on understanding the mystery of the matter/anti-matter imbalance which pervades our Universe, a phenomenon which is likely best approached via the study of CP violation in the B-meson system. He led the effort to establish the B Factory at SLAC, including being in charge of the team that produced the machine conceptual design and associated report. He is currently the Project Director of the SLAC-based B Factory (PEP-II), the accelerator facility designed and optimized for the study of CP violation in B meson decays. He is also the Technical Coordinator for the construction of the B-Factory detector (BaBar).

Jonathan has served on numerous advisory committees for national and international conferences and workshops. He has served on the SLAC Experimental Program Advisory Committee, served on the Advisory Board of Theoretical Advanced Study Institute (TASI), served as a member of the Particle Data Group Advisory Board (including one year as Chairman), served as a member of the American Physical Society (APS) Ad Hoc Committee on Particle Theory, served as a member of the Executive Board of the APS Division of Particles and Fields (DPF), has served as an Editor for Cambridge Press, and has served on the High Energy Physics Advisory Panel (HEPAP), a panel which makes input to the Department of Energy (DOE) on funding priorities for particle physics. Jonathan is a fellow of the American Physical Society.
