Andrew Ludlow is a research physicist in the Time and Frequency Division at the National Institute of Standards and Technology (NIST) and a lecturer in the Physics Department at the University of Colorado Boulder.  His main research interests include the development of optical atomic clocks, cold atom systems for quantum metrology, and ultrastable optical sources and laser interferometry.   He joined NIST in 2008 after receiving a Ph.D. in physics from the University of Colorado, and he currently leads the development of the ytterbium optical lattice clock there.


“Tweezer Clock” Offers New Possibilities in Timekeeping

An optical clock based on an array of individually trapped atoms provides a new twist in atom-based timekeeping. Read More »
