Research Interests

My research largely deals with understanding the role of entanglement entropy in quantum gravity. One aspect I have focused on is the need for edge modes in defining a notion of entanglement entropy in a theory with diffeomorphism symmetry, and the possible relation between edge modes and black hole entropy. I am also interested in techniques for computing entanglement entropy perturbatively in quantum field theories, and the application of these calculations to bulk reconstruction in holography.
