Giovanni Amelino-Camelia (born 14 December 1965) is an Italian physicist
Physics
Physics is a natural science that involves the study of matter and its motion through spacetime, along with related concepts such as energy and force. More broadly, it is the general analysis of nature, conducted in order to understand how the universe behaves.Physics is one of the oldest academic...

Quantum gravity
Quantum gravity is the field of theoretical physics which attempts to develop scientific models that unify quantum mechanics with general relativity...

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 (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
Quantum spacetime
In mathematical physics, the concept of quantum spacetime is a generalization of the usual concept of spacetime in which some variables that ordinarily commute are assumed not to commute and form a different Lie algebra...

.
Amelino-Camelia is famous also for being 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 (see Fermi Gamma-ray Space Telescope).
