Jabez J McClelland (Fed)

Jabez McClelland is the Group Leader of the Alternative Computing Group in the Nanoscale Device Characterization Division of the Physical Measurement Laboratory (PML). He received a B.A. in Physics and Music from Wesleyan University, and M.A. and Ph.D. degrees in Physics from the University of Texas at Austin. During his graduate studies he spent a year as a Fulbright Fellow at the Freie Universität Berlin. Jabez came to NIST as a Postdoctoral Research Associate in the Electron Physics Group, where he subsequently served as a Research Physicist and became Group Leader in 2006. In 2018 he assumed leadership of the Alternative Computing Group. His research at NIST has covered several topics, including spin-polarized low energy electron scattering from laser excited atoms, laser focused atomic deposition, metastable-atom lithography, deterministic single-atom sources, cold-atom ion sources, and neuromorphic computing. He has over 149 publications, has been a frequent invited speaker at international meetings, holds nine patents, and is considered one of the world experts on atom optics.
