Research

My research sits at the intersection of gravitation, black-hole physics, quantum field theory, holography and quantum information.

Black holes

Black-hole solutions and dynamics, regular geometries, collapse, interiors, extremality and singularities.

Higher-curvature gravity

Higher-derivative extensions of General Relativity, especially Einsteinian cubic gravity and the (generalized) quasi-topological gravities that we developed.

Entanglement in quantum field theory

Universal entanglement structures and constraints, quantum field theory from entanglement, and entanglement measures.

Holography and quantum gravity

Holographic entanglement, quantum aspects of spacetime, generalized symmetries, and gravity from entanglement.
