My area of research is the study of high temperature superconductors and other quantum materials. A central goal of this program is to understand the origin of high temperature superconductivity, in the cuprates and in the newer Fe-based compounds. These are spectacular manifestations of a diverse group of materials known as strongly correlated electron systems, materials that develop intricate and puzzling properties because their electrons interact strongly with one another, unlike simpler electronic materials such as silicon or copper.
