Author: David Bell

David C. Bell received his Ph D in physics from the University of Melbourne, Australia in 1997 and completed his postdoctoral studies at MIT in 1999. He was research faculty and principal investigator at the University of Minnesota from 2000 to 2002. In 2003, he joined the Center for Nanoscale Systems at Harvard University as a principal scientist and became the Manager for Imaging and Analysis in 2007. He has been a lecturer in applied physics at Harvard since 2003 and is a teaching professor at the Harvard Extension School. In 2007, he was a visiting scientist at the Department of Materials, Oxford University, UK. Dr Bell is one of the renowned experts in the field of elemental analysis using electron microscopy (TEM and STEM) and has co-authored a book on this subject. He has authored more than 70 research papers on the subjects of microscopy, materials science and biology and holds several patents. He is an elected Fellow of the Royal Microscopical Society, UK. Natasha Erdman received her Ph.D. in Materials Science and Engineering from Northwestern University (Chicago, IL) in 2002. After completing her Ph.D. she worked as a Senior Research Chemist at UOP LLC (currently Honeywell) in Des Plaines, IL focusing on investigation of structure-properties relationship in various catalysts using electron microscopy techniques. In 2004 Dr. Erdman as joined JEOL USA Inc., and currently serves as an SEM and Ion-Beam Product Manager. She has authored over 30 peer-reviewed papers on the subjects of microscopy, materials science, chemistry and biology and is a renowned expert on ion-beam based sample preparation techniques for electron microscopy.
