My research focuses on theoretical gravitational physics, black holes, and mathematical relativity.
I am a recognized expert on hidden symmetries, separability, and integrability of field equations in curved spacetime. I am one of the founders of a new subdiscipline of black hole thermodynamics known as black hole chemistry. In the last couple of years I have pushed forward our understanding of exotic black hole spacetimes, studied the interaction of ultralight bosons with rotating black holes, and proposed a new theory of higher curvature gravity. Most recently, I have become interested in relativistic quantum information and quantum detection of various spacetime features.
