Research Interests

I am a theoretical physicist working at the interface of quantum information theory and quantum gravity. I am interested in the question of what quantum phenomena such as entanglement tell us about the structure of spacetime and its dynamics; and conversely what gravity can teach us about entanglement.

Currently I am interested in:
* Entanglement entropy in field theory, quantum gravity and string theory.
* Soft modes in gauge theory and gravity.
* Gravity and gauge theory in lower dimensions and topological quantum field theory.
