One of the grand challenges of materials research is to control quantum degrees of freedom to discover new phenomena and manipulate the flow of energy, charge, and information. My group develops first-principles many-body and quantum field-theoretic methods to understand and predict how light-matter interactions and electron correlations govern the excitations and emergent properties of real materials. We study exciton transport and coherence, nonlinear and ultrafast optical response, and tunable or transient quantum phases, with applications to optoelectronics, quantum information, and energy science. Materials of interest include two-dimensional materials and heterostructures, defects, hybrid perovskites, and topological materials.
