My research field is string theory, quantum gravity, and conformal field theory. My most recent research is focused on the quantum theory of black holes, and its connection to quantum information theory, entanglement, and quantum chaos. Among other results, my recent work unearthed a link between how black holes store information and the properties of quantum error correcting codes. My work also contributed to the recent discovery that quantum black holes exhibit dynamical properties analogous to the Lyapunov behavior (`butterfly effect’) of chaotic quantum many body systems.
