Quantum Gravity (QG) is one of the most fundamental and longest standing issues of modern physics. There are now several candidate theories for QG (strings, loops, nonperturbative quantum field theories) and it is important to understand how to extract from them testable predictions. This is needed not only to solve old riddles (like singularities or the quantum aspects of black holes physics) but possibly also to deal with new ones, such as the nature of dark energy.

Fortunately in recent times there has been a flourishing of ideas and proposals on how to test mesoscopic (high-energy but still sub- Planckian) effects of different QG scenarios. This field of research goes under the general heading of QG phenomenology. It provides ways to put constraints on possible QG effects (for example departures from Lorentz invariance) but also stimulates new conjectures about the nature of the spacetime fabric and its behaviour near the Planck scale. In particular a key question is to understand how General Relativity arises at low energy from theories of QG.

The aim of this workshop is to put together different communities which are involved in this study: from pure theoreticians to phenomenologists to experimentalists, giving a broad view of the field through a series of colloquia aimed at a general audience (so that the gap between different communities could be bridged) and via daily, organized, discussion times.
