I worked broadly on the theory of quantum many-body dynamics and statistical physics. This means that I worked to understand and characterize the rich set of universal behaviors that can occur when many quantum mechanical degrees of freedom (ex: qubits) are interacting and out of equilibrium. Such systems can be realized with recently developed quantum simulators and quantum processors, so this field has a healthy interplay of theory and experiment. In my research, I employed both state-of-the-art numerical simulations and mathematical approaches to gain an understanding of these systems.
