About

My main research revolves around exploring quantum gravity by studying tensions that arise from combining general relativity and quantum physics, which often happens in the context of black holes and de Sitter spacetime. Some of the tools I use involve holography, quantum information, two-dimensional gravity, and non-Lorentzian geometry.
