Research Interests

I am interested in a wide range of topics related to gravity, quantum field theory, and astrophysics.
In particular, I enjoy thinking about quantum gravity phenomenology without an explicit formalism of quantum gravity.
This includes semi-classical Coleman-deLuccia tunnelling, and black hole information paradox.

I recently tried to solve the puzzle of entanglement development in the most general context, hoping to apply it to gravity without actually assuming a specific theory of quantum gravity.
