An experimental physicist, I am currently a professor of physics at the University of California, Davis, and a research associate in the Physics Department at Harvard University.
In the field of condensed matter physics, my career has focused on the realm of strongly correlated quantum materials and novel approaches to image their electronic structure. From heavy fermions to cuprate high temperature superconductors (HTSC) I have identified new states of quantum matter, exposed mechanisms of phase competition, broken symmetries, and topological transitions. I developed the first milliKelvin Scanning Josephson Tunneling Microscope (SJTM) to directly visualize the Cooper-pair condensate density in unconventional superconductors at the nanometer scale. This innovation led to the first direct detection and visualization of a spatially modulated electronic superfluid in any condensed matter system. I was awarded the Lee-Osheroff-Richardson prize for this work. Recently, I expanded upon my visualization methods for heavy fermions and found the telltale signature of an intrinsic topological phase deriving from strong correlations, the f-electron Dirac in-gap surface states of SmB6
