Areas of Research
My current research interests lie in studying the physics of correlated electron systems. While interactions between electrons in a typical metal are not large, in correlated electron materials, electrons interact strongly with one another producing interesting and exotic effects. My initial goal is to focus on a particular sub-set of correlated electron systems: the high temperature superconductors.
