William McGehee (Fed)

William McGehee is a UMD Postdoctoral Researcher in the Alternative Computing Group in the Nanoscale Device Characterization Division of the Physical Measurement Laboratory (PML). He received a B.S. in Physics from the Massachusetts Institute of Technology and a Ph.D. in Physics from the University of Illinois at Urbana-Champaign. His doctoral research focused on quantum simulation of strongly-correlated and disordered systems using ultracold Fermi gases. William is working with Jabez McClelland to build the second generation lithium-ion microscope for studying nanoscale ion transport in battery-relevant materials.
