I am interested in various aspects of strongly correlated electron systems, particularly at the interface of superconductivity and topology. I enjoy working closely with experiments, and I like thinking about simple-minded models to illuminate the puzzles of quantum materials. I’m currently thinking about the role of local interactions like Kondo and Hunds in the pairing mechanisms of heavy fermion superconductivity.
