Professor Abraham Seiden is the Director of the Santa Cruz Institute for Particle Physics, an organized research unit at the University of California, Santa Cruz. The institute has about 30 Ph. D. level scientists and focuses on research in particlephysics, particle astrophysics, and areas such as neurobiology, where technical innovations from particle physics allow unique contributions to other fields. He has been on the faculty at UCSC since 1978 and Director of the Institute from 1981. He was elected a Fellow of the American Physical Society in 1989 and was chosen for the Outstanding Faculty Award in the Natural Sciences at UCSC in 1995. Professor Seiden received a B.S. in Applied Physics from Columbia University in 1967. He received aM.S. in Physics from Caltech in 1970 and his Ph.D. from UCSC in 1974. His physics interests have included models for quark fragmentation and deep inelastic scattering; weak decays of heavy mesons, CP violation and mixing; and electroweak symmetry breaking at the next hadron collider. Professor Seiden has been the leader of a large number of detector construction projects for experiments in particle physics at accelerator centers throughout the world. This has included leading the construction of several large drift chambers and more recently particle tracking detectors using arrays of silicon detectors and VLSI electronics. His present focus is on particle tracking in the ATLAS detector at the Large Hadron Collider at CERN in Geneva, Switzerland.
