Our research efforts focus on designing new inorganic solid state functional materials for emerging applications in the fields of: electronics, including topological insulators, solid-state energy conversion and storage, superconductivity, magnetic materials, catalysis, durable high performance color pigments, efficient environmentally benign chemical synthesis processes (e.g. rapid synthesis of high-temperature materials using microwave radiation). We are particularly inspired by the challenges involved in developing design concepts for materials with conflicting or contraindicating properties, as seen in: thermoelectrics, multiferroics, high K dielectrics, negative thermal expansion materials. The team has a track record of making important and exciting scientific breakthroughs in materials chemistry. Discoveries have been given prominent coverage throughout the world in leading newspapers and magazines – including The New York Times, TIME, NPR, National Geographic Magazine, C&EN news, La Monde (France), Geo (Germany), Chemistry World (UK), and The Hindu (India).
