Personal presentation

I am a PhD student at the University of Nottingham, and a visiting student at the Ludwig Maximilians University of Munich, working at the interface of quantum information theory and quantum gravity. I am interested in the role played by entanglement in the fundamental structure of spacetime, and my research focuses on the characterization of quantum gravity models from a quantum information perspective.

Ongoing projects

I am working on the correspondence between the group field theory approach to quantum gravity and tensor networks, with the aim of importing quantum information techniques in the study of quantum gravity issues. In collaboration with Dr. Daniele Oriti and Dr. Goffredo Chirco, I am investigating the holographic properties of group field theory states by relying on such a correspondence. I am also working with Roukaya Dekhil and with Dr. Oriti to the implementation of entanglement measures in the group field theory context.
