"For their leading contributions to the discovery of the long b-quark lifetime with the MAC and Mark II experiments at SLAC. The unexpectedly large value of the b-quark lifetime revealed the hierarchy of the Cabibbo-Kobayashi-Maskawa quark mixing matrix."

Research Interest Synopsis
The largest body of my research has been focused on high energy particle experiments, at the energy frontier, with a keen interest in testing symmetries and the study of the heaviest quarks, bottom and top.
My interest in detector R&D and particle accelerators has been driven primarily by their importance to the field of High Energy Physics. Building on that, I also collaborated for several years on proton therapy applications and medical physics detectors with colleagues at Brookhaven National Laboratory and the Hospital of the University of Pennsylvania.
Participation in and contribution to accelerator advances and the challenges associated with the next generation of high energy accelerators, including the Linear Collider and VLHC, are in the forefront of my future research plans. In particular, I am becoming involved with an international collaboration of accelerator physicists planning to further development superconducting RF techniques. The collaboration is called SMTF (Superconducting Module Test Facility).
