Pittsburgh Center's Director Named APS Fellow

PITTSBURGH -- Ralph Roskies, co-scientific director of the Pittsburgh Supercomputing Center, has been named a fellow of the American Physical Society. He was cited for his "fundamental contributions to theoretical high-energy physics and the promotion of computational physics through the Pittsburgh Supercomputing Center."

Roskies, a professor of physics at the University of Pittsburgh, received the honor during the society's annual council meeting Nov. 21 in Santa Fe, N.M. He was among 198 APS members named fellows this year. The society, which has 43,710 members in 127 countries, currently has 4,510 fellows.

Roskies' high-energy physics work involved a long-standing collaboration with Michael Levine, co-scientific director of the Pittsburgh Supercomputing Center and a professor of physics at Carnegie Mellon University. The two researchers applied symbolic and numerical computation to a precise calculation of the anomalous magnetic moment of the electron. At the time, the calculation was one of the largest computations ever performed.

Roskies' other work involved lattice-field theory computations with Anthony Duncan of the University of Pittsburgh and strong-coupling and high-temperature series work with Carl Bender of Washington University in St. Louis.

Roskies and Levine were instrumental in establishing the Pittsburgh Supercomputing Center, which, Roskies says, "has enabled a very wide range of computational physics to be carried out, in such diverse areas as quantum chromodynamics, magnetic property of materials and astrophysics."

The APS, which was established in 1899 at Columbia University, has 23 subunits, and no more than 0.5 percent of each area's members can become fellows each year.

The Pittsburgh Supercomputing Center, a joint project of Carnegie Mellon University and the University of Pittsburgh together with Westinghouse Electric Corporation, was established in 1986 by a grant from the National Science Foundation with support from the Commonwealth of Pennsylvania. Its purpose is to develop and make available state-of-the-art high-performance computing for scientific researchers nationwide.
