Michael Romalis is professor of physics at Princeton University. He received his B.S. in physics from the Illinois Institute of Technology, in Chicago, and his Ph.D. in physics from Princeton University in 1997. He is interested in applications of atomic physics techniques to fundamental questions about the workings of the Universe as well as to practical applications in other areas of science. His current research interests include atomic magnetometers, nuclear spin co-magnetometers and Rydberg microwave electric field detectors. In addition to practical applications, these quantum sensors are used to search for violations of Lorentz invariance, new spin-dependent forces and possible coherent dark matter signals. He was made a Fellow of the American Physical Society in 2012 and received the Francis Pipkin Award in 2010.
