My name is Romain Ruzziconi. I am a Marie Skłodowska-Curie Global Fellow, currently based at Harvard University in the Center for the Fundamental Laws of Nature and the Black Hole Initiative. My research in high-energy theoretical and mathematical physics focuses on holography, classical and quantum gravity, string theory, asymptotic symmetries, scattering amplitudes, twistor theory, and Carrollian physics.
Recently, I have been developing a framework for flat-space holography by establishing the interplay between Carrollian physics and celestial amplitudes, and clarifying its relation to the flat space limit of the AdS/CFT correspondence. I have also investigated the symmetries of asymptotically flat spacetimes using covariant phase space methods and twistor theory.
