Gary Horowitz is a Distinguished Professor of Physics at the University of California, Santa Barbara. He received his B.A. in physics at Princeton University in 1976 and Ph.D. in physics at the University of Chicago in 1979. After a couple postdocs, he joined the faculty in Santa Barbara in 1983. Horowitz has significantly advanced our understanding of both classical and quantum gravity. He played a key role in the discovery of Calabi-Yau spaces (a way to consistently compactify string theory), extended black holes called black branes, the string-black hole transition, and holographic superconductors (a way to relate general relativity and superconductivity). Horowitz was awarded the Einstein Prize (the highest award by the American Physical Society for work in gravitational physics) in 2023. He has been a member of the US National Academy of Sciences since 2010, and of the American Academy of Arts and Sciences since 2013.
