RESEARCH :

I am a theoretical physicist studying condensed matter and more specifically the behavior of electrons in solid state materials. My primary interest is in Dirac materials, including graphene, topological insulators and semimetals (see here for a review). I have investigated transport properties in hybrid junctions between superconductors and various Dirac materials. I am also interested in the nonlinear coupling of light with Dirac matter (here) and superconductors.
