Our group’s interests include the behavior of liquid, colloidal and living systems on length scales that are much greater than atomic.  A particular aim has been to understand the social behavior of microbes along with the physicochemical systems that enable their intercellular communication. 

A central focus of our current work is a new form of X-ray spectroscopy based on inelastic scattering coincident with deexcitation radiation. We believe that this is a potent approach for studying quantum matter. Here our focus is on correlated electron behavior and new photon effects in solids and atoms.
