University of California, Riverside, CA 1964-70 MS Physics 1966
PhD Physics 1970


1988 - present Trainer and consultant on: 1) radiation safety (laser, rf and ionizing), and 2) laser and electro-optics technology. Served as an expert witness on laser injury cases for both defense and plaintiff. Member of 1) the ANSI Accredited Standards Committee Z136 on the Safe Use of Lasers, and 2) six ANSI Z136 Standards and Technical Subcommittees including Safe Use of Lasers in Health Care Facilities.
1980 - 1988 Professor of Physics at Pacific Union College. Taught quantum mechanics, biophysics, and laser theory and technology. Part-time trainer and consultant on radiation safety (laser, rf and ionizing). Served as radiation physicist for thirteen hospitals in California. Started High-Rez Diagnostics.
1979 - 1980 Liaison Scientist for the Office of Naval Research, London Branch Office. Primary responsibility was the assessment of research conducted throughout Europe in the fields of lasers, electro-optics and solid state physics.
1975 - 1979 Head, Quantum Optics and Semiconductors Branch, U.S. Naval Air Warfare Center, China Lake, CA. Projects which I initiated and/or participated in during this period include: DARPA sponsored UV laser damage threshold program, aerosol scattering of laser radiation at 249nm, integrated optics, surface acoustic wave-scanned infrared imaging, laser gyros, and holography.
1974 - 1975 Assistant Technology Administrator, Naval Air Systems Command (Code 360), Washington, D.C., with the responsibilities of both monitoring and initiating exploratory development contracts in lasers and electro-optics.
1969 - 1974 Physicist (Supervisory Physicist 1971-1974), U.S. Naval Air Warfare Center, China Lake, CA. Performed organic dye laser research and development including tuning techniques, exciplex studies, and new laser excitation techniques.
1964 - 1969 Graduate student, University of California, Riverside, CA. BuWeps Fellow 1964-6 and Naval Weapons Center Fellow 1966-7. Experience gained in cryogenics, infrared reflectometry, crystal growing and low-temperature microwave resonance techniques while conducting experimental research leading to the PhD degree.
1962 - 1964 Physicist, U.S. Naval Air Warfare Center, China Lake, CA. Conducted experiments in the areas of mechanical Q-switching of solid-state lasers, laser amplifiers, and the optical properties of ocean water.
