Complex systems of many interacting degrees of freedom can display qualitatively new physics with no analog in few body systems. The search for such emergent phenomena is one of the central goals of condensed matter physics (and its close cousin, statistical physics). My research is focused on the search for new emergent phenomena in quantum many body systems with strong interactions and/or strong randomness. I do theory work on quantum systems both in and out of equilibrium. Particular topics of interest include (but are not limited to) nonequilibrium quantum statistical mechanics, many body localization and thermalization, field theory of correlated systems, Dirac fermions, unconventional superconductors and the interplay of disorder and interactions; fractons; nonlinear spectroscopy and ultrafast dynamics in quantum materials.
