Jeffrey Sherman (Fed)

Jeff Sherman is the group leader for the Time Realization and Distribution Group at the National Institute of Standards and Technology. Jeff works to maintain and improve NIST systems that produce and distribute official U.S. time, time-interval, and frequency signals, which are based on an ensemble of atomic clocks and frequency references. Jeff’s research career has centered around high-precision measurements in optical-atomic systems and includes a Ph.D. in Physics from the University of Washington (2007), postdoctoral work at the University of Oxford, and a National Research Council research associateship at NIST.
