I have been exploring the quantum nature of spacetime from diverse perspectives: my PhD mainly focused on a path integral approach of quantum gravity, as well as a phenomenological theory. After graduate school I have been exploring the symmetries and anomalies of the near horizon gravitational phase space and the horizon microstate counting, since they hint at a holographic description of near horizon quantum gravity. Recently I am very excited to join Ognyan Oreshkov’s group in ULB, where I plan to study indefinite causal structure, and its interplay with locality and diffeomorphisms. Eventually I want to describe the causal structure for the quantum gravity regime.
