Three Brookhaven Lab
Physicists Named American Physical Society Fellows
Upton, NY — Robert Pisarski,
Samuel
Aronson, and Serban Protopopescu (front to back in photo) — physicists at
the U.S. Department of Energy’s Brookhaven National Laboratory
— have been named Fellows of the American Physical Society (APS),
a professional organization for physicists with over 40,000
members. APS Fellowship is limited to no more than one half of one
percent of its membership, and election for this honor indicates
recognition by scientific peers for outstanding contributions to
physics.
Samuel Aronson’s
citation on his Fellowship certificate reads, “For contributions
to nuclear and particle physics, including the physics of neutral
Kaons, and the leadership, design and construction of the major
experiments, D0 ("D-zero") at Fermilab and PHENIX at
RHIC.”
Kaons are elementary
particles that Aronson studied to understand better how they fit
into the Standard Model, the modern theory of fundamental physics.
The D0 experiment at the U.S. Department of Energy’s Fermilab in
Chicago was successful, in 1995, in finding the top quark, an
elementary particle whose existence helps to prove the Standard
Model. And, since 1991, Aronson headed the effort to design,
build, install and operate PHENIX, an experiment built by a
collaboration of over 400 people from 50 laboratories and
universities around the world. PHENIX is a detector at
Brookhaven’s newly operating Relativistic Heavy Ion Collider
(RHIC),
which may help scientists discover and study the quark-gluon
plasma, a state of matter predicted to have existed in the
earliest moments of the universe.
Aronson earned an A.B. in physics from
Columbia University in 1964 and a Ph.D. in physics from Princeton
University in 1968. From 1968 to 1977, he was a postdoctoral
fellow at the University of Chicago and a faculty member at the
University of Wisconsin. He joined BNL in 1978. He was associate
chair for the Physics Department in 1987, and deputy chair for the
department in 1988. He became a senior physicist in 1991.
Robert Pisarski was cited “For important
contributions to the study of QCD at high temperatures.” QCD
stands for quantum chromodynamics, which is a theory of the
nuclear interactions among quarks, the fundamental constituents of
matter. Pisarski is studying the interaction of quarks at a
trillion degrees at RHIC, a temperature at which they are expected
to change into the quark-gluon plasma.
After earning a B.S. in physics from Yale
University in 1975 and a Ph.D. in theoretical physics from
Princeton University in 1979, Pisarski became a J.W. Gibbs Fellow
at Yale in 1979. He then worked at the Institute for Theoretical
Physics, Santa Barbara, California, from 1981 to 1984, and at
Fermilab from 1984 to 1989, before he joined Brookhaven in 1989.
From 1997 to 1999, he was head of Brookhaven’s Nuclear Theory
Group, and, from 1999-2000, he was deputy director for theory for
the RIKEN/BNL Research
Center. He was promoted to senior scientist
in 2000.
Serban Protopopescu was cited “For his
individual contributions and leadership in the discovery of the
top quark at the D0 Experiment and for software simulation and
algorithm development.” Protopopescu was one of the original
proponents of Fermilab’s D0 particle detector and was a
leader in the development of software for the detector.
Protopopescu earned a B.A. in physics from
Princeton University and a Ph.D. in experimental high energy
physics from the University of California, Berkeley in 1972. He
joined Brookhaven in 1972 as an assistant physicist, became an
associate physicist in 1976, and physicist in 1988.
The U.S.
Department of Energy's Brookhaven National Laboratory conducts
research in the physical, biomedical, and environmental sciences,
as well as in energy technologies. Brookhaven also builds and
operates major facilities available to university, industrial, and
government scientists. The Laboratory is operated by Brookhaven
Science Associates, a partnership led by Stony Brook University
and Battelle, a nonprofit applied science and technology
organization.
