Our research is best described as materials theory, broadly defined. We use a variety of techniques chosen to suit the problem at hand, ranging from first-principles density functional theory to dynamical mean field theory, empirical interatomic potentials, photonic bandstructures or effective continuum theories such as Landau-Ginzburg. Often, our work is computationally intensive, but sometimes just a pencil and paper is enough. Yikes! I'm on video- see a brief interview in Naples on properties of carbon nanotubes.
