Thank you to the following alumni for your show of support and interest. Your
overwhelming response is encouraging and appreciated by the Faculty and Staff of
the USC Department of Physics and Astronomy.

Mr. Herbert J. Wintroub, B.A. Physics '50, is, presently, a Distinguished Engineer and
principal member of the technical staff for the Engineering and Technology Group at The
Aerospace Corporation
, after working in management for many years in the Electronics
Research Laboratory. His current work is concerned with developing concepts for advanced
space communication and data-relay systems and the supporting device and component
technology. The emphasis is on systems in the upper microwave and millimeter-wave regions.
Another professional/personal interest is developing closer relationships between the
corporation and the academic community through arrangements such as the industrial
affiliates. On a personal basis, he is interested in mentoring younger Members of the Technical
Staff (MTS) and new graduates of our universities.

Mr. Duane Olinger, B.S. Physics '62, has retired after thirty years of applying Kepler
mechanics in the aerospace industry. He lives in Norman, Oklahoma.

Dr. Roger A. Lilly, B.S. Physics '61; M.A. Physics '64, is, currently, the Chair of the

years as an engineer with the Department of Defense and the Southern California Gas
. Crain writes, "After graduating in Physics in 1968, I took my Masters and Ph.D. in
the Materials Science Department at USC (back then, it was called `Applied Physics' so it
seemed like a very natural progression). My professors in Physics most fondly remembered
include: Drs. Judge, Wagner, Waddell, Cole, and Ogawa. All of us students were frightened
at the thought of having to take theoretical physics from Dr. Nodvik . . . ."

Dr. Craig Stephen Stern, B.A. Astronomy '69; Pharm.D. '76; M.B.A. Business
Administration '94
, has worked as an independent consultant to multi-hospital corporations

He is responsible for the design and fabrication of large aperture diffractive optics for high
power laser fusion applications. He writes, "We fabricate random phase plates, diffraction
gratings, and Fresnel lenses at approximately 1 meter size for use in pulse compression,
spatial beam smoothing, laser beam shaping, and space applications. In spite of their large
size, the optics have feature sizes in the micrometer range; so our diffractive optics can be
termed `meter size, yet micron precise.'"

Dr. David M. Tralli, B.S. Physics '81, went on to receive a Ph.D. in Geophysics from
University of California, Berkeley
in 1986, and an MBA in Technology Marketing from the

Commercialization Office which he designed and formed in 1996 to develop new business for
JPL by working with the commercial sector to target the needs of emerging markets.
Collaborative technology development and applications research proposals have resulted in
over $3 million in funding. Additionally, Tralli's office supports the technology
commercialization requirements of multi-million dollar space exploration missions at JPL.
Current market interests include property insurance risk securitization, carbon offsets trading,
modern agriculture, and collaborative environments. Technologies and applications under
development include synthetic aperture radar, imaging spectroscopy, and information
systems. Tralli has been with JPL for 12 years, and has fifteen peer-reviewed publications in

technologies for multi-hazard loss estimation. He lives in Arcadia with his wife and son.

Dr. Shin-Tson Wu, Ph.D. Physics '81, is working to develop new liquid crystal materials
and devices for direct-view and projection displays and for laser beam steering. Wu writes,
"In the display area, active matrix addressed liquid crystal display has become the dominant
technology for notebook computers and is penetrating to the desktops. Recently, a liquid
crystal based optical phase array has been demonstrated successfully to steer a high power
laser beam for laser communication."

Mr. Vance Breshears, Jr., B.S. Physics'83, has recently published a technical paper,
entitled "Design Approach for Multi-Channel Sound Reinforcement Systems", at the Audio

months in 1993 at the MIT Lincoln Lab in Lexington, Massachusetts, as a visiting scientist in
a cooperative research agreement with MIT/LL to transfer Yb:YAG laser technology to
Hughes. He writes, "We, currently, hold the world record in output power at 1 kW of
average power from a tiny 3-mm diameter rod with an optical-optical efficiency of 25%. This
laser medium is ideally suited for high average power applications (both, high repetition rate
and, also, cw) and has active sponsorship for, both, military and industrial applications. We
have been fortunate to receive a number of awards because of this work." Sumida, himself,
has been awarded for this work. His invited paper was awarded the 1997 Best Paper Award
at the IRIS Specialty Group on Active Systems Conference, and he and his colleagues
received the Outstanding Paper Award from HRL Laboratories for their 1997 journal article
published in the IEEE Journal of Selected Topics in Quantum Electronics. Furthermore, he is
a member of the Optical Society of America and the American Scientific Affiliation. In
addition to his research activities, Sumida still finds time to be a "soccer dad" who plays a
couple times a week on his lunch break, helps to coach his daughter's and older son's AYSO
soccer teams, and became an official referee, as well.

Saundry is married and lives in Germantown, Maryland, with his wife, Claire, and a two-year
old son, Andrew.

Dr. Katri Huitu, Ph.D. Physics '92, is working on supersymmetric and extended gauge
models of particle physics and is a particle theory and cosmology group leader in the Helsinki
Institute of Physics
, as well as a member of the Institute Board. Huitu writes, "On the personal

Dr. Qiang Luo, Ph.D. Physics '93, is teaching a one year course at Peking University in
physics to sophomore psychology students covering mechanics, thermal physics, electricity
and magnetism, optics, and modern physics. He is working with Professor Gao, Z.X. to
investigate vortex dynamics in type-II superconductors and uses magneto-optic imaging
techniques to observe flux motion in high temperature superconductors. Luo writes,
"Currently, there is renewed interest in Bose-Einstein condensation (BEC) after the direct
experimental observation of BEC for trapped atoms in 1995. BEC is relevant to high
temperature superconductors, too. Most likely, high temperature superconductors lie in the
crossover regime between weak-coupling BCS theory where Cooper pairs form below the
superconducting transition temperature, and BEC of pre-exist bosons. Professor Han, R.S.
and I are working on theoretical issues in this area."
