I am interested in a wide range of activities related to the optical properties of condensed matter systems and the physics of non-Fermi liquids. In most cases, I try to obtain analytical results that can help establish the relationship between physical observables and a minimal set of system parameters. I primarily rely on standard techniques in optics, many-body physics, and quantum field theory, using numerical methods as needed. 

Recently, we developed a field-theoretic functional renormalization method that is useful for studying quantum critical systems in two dimensions.
