My research interests include strongly disordered and non-equilibrium systems, with specific applications to materials science, molecular electronics, and biophysics.
Our main focus is a self-consistent theory of structural and electronic excitations in amorphous materials. Several optical and electronic anomalies that are unique to semiconductor glasses have resisted systematic efforts for decades, including light induced ESR, midgap absorption, and insensitivity to conventional doping. Our findings show these anomalies are not a generic consequence of disorder, but, instead, result from the high structural degeneracy of glasses. An important component of our research is the prediction of the structure and glassforming ability of specific substances of interest in applications, a task currently inaccessible to computer technology.
