Nigel Browning received his undergraduate degree in Physics from the University of Reading, U. K., and his Ph.D. in Physics from the University of Cambridge, U. K. After completing his Ph.D. in 1992, he joined the Solid State Division at Oak Ridge National Laboratory (ORNL) as a postdoctoral research associate before taking a faculty position in the Department of Physics at the University of Illinois at Chicago (UIC) in 1995. In 2002, he moved to the Department of Chemical Engineering and Materials Science at the University of California-Davis (UCD) and also held a joint appointment in the National Center for Electron Microscopy (NCEM) at Lawrence Berkeley National Laboratory (LBNL). In 2005 he moved the joint appointment from LBNL to Lawrence Livermore National Laboratory (LLNL) to become project leader for the Dynamic Transmission Electron Microscope (DTEM). In 2009, he also joined the Department of Molecular and Cellular Biology at UC-Davis to focus on the development of the DTEM to study live biological structures. Dr. Browning held the rank of Full Professor in the Department of Chemical Engineering and Materials Science and the Department of Molecular and Cellular Biology and was the Director of the Interdisciplinary Center for Electron Microscopy (ICEM) at UC-Davis. His research focused on the development of new methods in electron microscopy for high spatial, temporal and spectroscopic resolution analysis of engineering and biological structures.
