David is an Ohio Research Scholar, Professor of Materials Science and Engineering and Director of the Center for Electron Microscopy and Analysis (CEMAS) at The Ohio State University. A chemistry graduate from the University of Glasgow, David did his PhD in Physics at the University of Cambridge. Before moving to the USA in 2011, David was co-director of the London Centre for Nanotechnology as well as Director of Research and Deputy Head of the Department of Materials at Imperial College London.

David is an expert in the development and application of scanning transmission electron microscopy (STEM) and electron energy-loss spectroscopy (EELS) as a sub‐nanometer scale probe of chemistry, structure and bonding. He has extensive experience in the application of STEM-EELS to the study of problems in solid‐state chemistry and materials science including structural and compositional variations in high‐k oxides, short range magnetic order in transition metal oxides, interfaces in fuel cells, photovoltaics, multiferroics and biomaterials.  He is a fellow of the Royal Society of Chemistry and the Institute of Materials. 

CEMAS is a state-of-the-art facility houses over $39M worth of electron and ion microscopes performing at or beyond manufacturer specifications, CEMAS was conceived to drive the application of state of the art electron microscopy techniques to strategic research challenges in the physical, engineering, life and medical sciences.  The recent addition of extensive cryo-electron microscopy techniques is enabling CEMAS to drive the convergence of physical and life sciences research in imaging and analysis.
