My current research is focused on “Nodal Materials” which are correlated electron systems where the Fermi sea can be collapsed into a set of points or lines. The most famous example of such a system is graphene, an allotropic form of carbon, which consists of a giant molecule formed by a single atomic layer of graphite. Other interesting examples include topological/Chern insulators, and more recently, a new class of three dimensional materials known as Weyl and Dirac semimetals, which mimic electronic properties of relativistic particles in 3+1 dimensions. 

In Dirac materials, I am particularly interested in the problem of electron-electron interactions, and in the possible emergence of new quantum states of matter with possible topological order.  An overview in the problem of electron-electron interactions in graphene can be found in my recent review paper in Reviews of Modern Physics. 

I have been working in a variety of problems in theoretical Condensed Matter physics, including Many body effects in systems with Dirac-like quasiparticles, Superconductivity in exotic systems, Quantum Hall effects, Quantum criticality in low dimensions and topological effects.   My interests span also over layered materials with exotic Fermi surfaces, and atomic multilayered crystals, which offer a wire range of possibilities for the emergence of new quantum phenomena. More recently I have been interested in hyperhoneycomb and Lieb lattices, which could host interesting new interesting topological states.
