Giovanni Amelino-Camelia
Giovanni Amelino-Camelia 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 that is the idea of introducing the Planck length in physics as an observer-independent quantity, obtaining a relativistic theory. The principles of doubly special relativity probably imply the loss of the notion of classical spacetime; this led Amelino-Camelia to the study of non-commutative geometry as a feasible theory of quantum spacetime.
Amelino-Camelia is the initiator of "quantum-gravity phenomenology", for being the first to show that with some experiments under reach of current technology sensitivity to Planck-scale effects is feasible.
