Research

My current research interests involve physics educational research & innovative instruction in introductory physics & computational physics, applications of information-theoretical techniques & data analysis, and theoretical condensed matter physics. I am fascinated by the complex phenomena that emerge in strongly correlated electron systems, such as high-temperature superconductivity, and studied the effect of inhomogeneities in high-temperature superconductivity using the Dynamical Cluster Approximation (DCA).
