My broad research interests lie in areas of statistical mechanics and quantum many-body physics. In particular, I study various non-equilibrium aspects of quantum many-body systems, including the effects of interaction range, disorder, inclusion of non-Hermitian components, and other factors. Recently, my focus has been on understanding the approach to equilibrium in quantum many-body systems, in light of the Eigenstate Thermalization Hypothesis (ETH) and its connection to free probability theory.
