Professor John Marohn's group is focused on imaging the structure and function of materials at the nanometer scale.  We are pushing magnetic resonance imaging to nanoscale resolution in order to study individual biomolecules and are developing and applying tools to study charge in thin-film devices -- including the drift, diffusion, trapping, and generation of charge from light.
