One of the central themes of my research are the connections between the physics of correlations and novel quantum/topological effects. My current research interests involve studying the universal quantum critical behavior and the physics of correlations in systems with exotic Dirac or Weyl quasiparticles, and also the physics of incoherent metals that entirely lack quasiparticles. The latter can be exemplified in the physics of strange metal phases, which are notorious for their linear temperature dependence of the resistivity, and may have connections with the hydrodynamic behavior observed in seemingly unrelated out-of-equilibrium systems, such as the quark-gluon plasma. 

In addition, I am interested in Moire heterostructures, which are a perfect prototype system for observation of strongly correlated phases, and possibly, for the design of novel tunable topological devices. Subjects of interest also include the physics of quantum thermalization and out-of-equilibrium effects in many-body correlated systems.  My earlier work in Dirac materials is summarized in a review paper in Reviews of Modern Physics.
