Giovanni Amelino-Camelia (born 14 December 1965) is an Italian physicist of the University of Rome La Sapienza who works on quantum gravity. He is the first proposer of Doubly special relativity[1] that is the idea of introducing the Planck length in physics as an observer-independent quantity, obtaining a relativistic theory (like Galileian relativity and Einstein's special relativity). The principles of Doubly special relativity probably imply the loss of the notion of classical (Riemannian) spacetime; this led Amelino-Camelia to the study of non-commutative geometry as a feasible theory of quantum spacetime. Amelino-Camelia is famous also for being the initiator of "quantum-gravity phenomenology", for being the first[2] to show that with some experiments under reach of current technology sensitivity to Planck-scale effects is feasible (see Fermi Gamma-ray Space Telescope).
