From Wikipedia, the free encyclopedia

Stuart A. Raby is an American physicist and professor at The Ohio State University, known for his work in theoretical physics. His research focuses on physics beyond the Standard Model, including the grand unification of fundamental forces, supersymmetric theories, and string theory model building.

Early life and education

[edit]

Raby was born in the Bronx, New York, and raised in Palisades Park, New Jersey, he completed his undergraduate education at the University of Rochester in 1969. He pursued graduate studies at Tel Aviv University, earning an M.Sc. in physics in 1973 under the supervision of Professor David Horn (Israeli physicist). His research focused on quantum mechanics and mathematical methods for physicists. He continued at Tel Aviv University for his doctoral studies, receiving his Ph.D. in 1976 under the guidance of Professor Lawrence Paul Horwitz.

Academic career

[edit]

From 1976 to 1978, Raby served as a research associate at Cornell University. He then joined Stanford University as an acting assistant professor from 1978 to 1980, teaching advanced graduate courses in electrodynamics, statistical mechanics, and general relativity.

In 1980, Raby transitioned to the Stanford Linear Accelerator Center (SLAC) as a research associate.[1] The following year, he began his association with the Los Alamos National Laboratory, initially as a temporary staff member.[2] Over the next eight years, he rose to the position of group leader of T-8 in the Theory Division, overseeing research in theoretical particle physics.

During 1982–1983, Raby held a visiting associate research scientist position at the University of Michigan. In 1989, Raby joined The Ohio State University as a full professor of physics, a role he continues to hold.[3]
