Professor Cronin-Golomb graduated from University of Sydney with a B.Sc. in Physics and from Caltech with a Ph.D. in Physics. His research there was on photorefractive nonlinear optics in the group of Amnon Yariv where he discovered the first photorefractive self-pumped phase conjugate mirror. He worked for two years at Ortel Corporation, researching the application of photorefractive devices to semiconductor lasers. He joined Tufts University in 1986 as associate professor of Electrical Engineering and is now a member the Department of Biomedical Engineering. In 1996-1997 he was a visiting associate professor at Stanford University in Steve Chu's group.
