William McGehee is a physicist in the Atomic Devices and Instrumentation group in the Time and Frequency division at NIST. His research focuses on the development of fieldable quantum sensors based on laser-cooled gases and atomic beams using novel vacuum technology, integrated photonics, and optical spectroscopy. He has a long-standing interesting in applications for laser-cooled atoms including quantum simulation of highly-correlated systems and the production of high-brightness ion sources for nanotechnology applications. He received a B.S. in Physics from the Massachusetts Institute of Technology in 2008 and a Ph.D. in Physics from the University of Illinois at Urbana-Champaign in 2015.
