My primary research interests are in the fields of solid state chemistry and electrochemistry; particularly solid state ionics, which embraces ionically conducting solids and intercalation compounds. I am interested in the fundamental science of ionically conducting solids (ceramic and polymeric materials) and intercalation compounds, in the synthesis of new materials with new properties or combinations of properties, in understanding these properties and in exploring their applications in new devices, especially energy storage devices such as rechargeable lithium batteries. Although ionically conducting solids represent the starting point for much of our research, we have extended our interests well beyond the confines of this subject alone.
