Giovanni Amelino-Camelia (born 14 December 1965, Naples) 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).
