I began a PhD in mathematical physics at the IRMAR (Rennes, France) under the supervision of Dimitri Petritis in October 2021. My work initially aimed at exploring a set of different approaches for quantum gravity based on the discretization of spacetime at the Planck scale, attempting to make the geometry emerge from its causal or informational structure only. This idea is in particular supported by a deep result in Lorentzian geometry, the Hawking – King – McCarthy – Malament theorem.

However, before tackling the specific problems of quantum gravity, I consider essential to shed light on the foundational problems in standard quantum mechanics, in particular the measurement problem and the emergence of classicality and objectivity. I have therefore mainly worked for now on the theory of decoherence, quantum information theory, and the mathematical and philosophical foundations of quantum mechanics.

The provisional title for my PhD thesis is: The ontological problem in quantum physics and the emergence of a backgroundless spacetime in the light of the theory of decoherence.
