My research focuses on non-perturbative aspects of quantum field theory and string theory, with applications to the dynamics of strongly coupled quantum systems that arise in both high energy and condensed matter physics. One central theme of my research program is to explore the power of symmetries, by identifying generalized symmetry principles and anomalies with ideas from mathematics, as well as constraining and solving strongly coupled theories with non-perturbative tools such as conformal bootstrap and supersymmetry. More recently, I am working on fundamental properties of extended defect operators in quantum field theory.
