My current work involves studying the non-smooth structures of black hole horizons. These structures may give us clues about black hole entropy, in a similar way to how non-smooth entangling surfaces yield additional terms in the entanglement entropy. This work is done in collaboration with my supervisor Prof. Harvey Reall.
