David has made significant contributions to the development of neutron diffraction and X-raypowder diffraction. Highlights include the comprehensive crystal-structure analysis of C60 (Buckminsterfullerene),[7] and the accelerated determination of molecular crystal structures through his computer program, DASH.[8] His theoretical work is based on the application of Bayesian probability theory in areas ranging from structural incompleteness to parametric data analysis.[1]
David's materials focus is in energy storage, beginning with his research on lithium batterycathodes. More recently, he has worked on lightweight hydrogen storage materials[9][10] such as reversible imide-amide systems.[11] Following his discovery of a new family of ammonia-decomposition catalysts, his main energy research interests are in materials that facilitate the safe and effective utilisation of ammonia as an energy vector.[1]
