Jabez J McClelland (Fed)

Group Leader

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 139 publications, is a frequent invited speaker at international meetings, holds nine patents, and is considered one of the world experts on atom optics. He currently leads projects on focused ion beam sources based on laser cooled atoms and measurements for neuromorphic information processing.
