Renu Sharma

Dr. Renu Sharma is a Project Leader in the Nanoscale Imaging Group. She received a B.S. and B.Ed. in Physics and Chemistry from Panjab University, India, and M.S. and Ph.D. degrees in Solid State Chemistry from the University of Stockholm, Sweden, where she had a Swedish Institute Fellowship. Renu joined the CNST at NIST in 2009, coming from Arizona State University (ASU), where she began as a Faculty Research Associate in the Department of Chemistry and Biochemistry and the Center for Solid State Science, and most recently served as a Senior Research Scientist in the LeRoy Eyring Center for Solid State Science and as an affiliated faculty member in the School of Materials and Department of Chemical Engineering. Renu has been a pioneer in the development of environmental scanning transmission electron microscopy (E(S)TEM), combining atomic-scale dynamic imaging with chemical analysis to probe gas-solid reactions. She has applied this powerful technique to characterize the atomic-scale mechanisms underlying the synthesis and reactivity of nanoparticles (including catalysts), nanotubes, nanowires, inorganic solids, ceramics, semiconductors, and superconductor materials. Renu has received a Bronze Medal of Service from Department of Commerce for developing new measurement techniques, Deutscher Akademischer Austauschdienst (DAAD) Faculty Research Fellowship, is a past President of the Arizona Imaging and Microanalysis Society, Fellow of Microscopy Society of America and has given over 90 invited presentations, and published 5 book chapters and over 200 research articles. At the CNST, Renu has established an advanced E(S)TEM measurement capabilities, that combines Raman spectroscopy, cathodoluminescence with electron diffraction, electron spectroscopy, high-resolution imaging and plasmonics, for nanoscience research and is contributing her research expertise to the operation of a TEM facility in the NanoFab.
