Quantum gravity is a fast growing field in physics and its study is expected to give answers of the short-distance behaviour of theories of gravitation. Probing the high-energy and high-curvature regimes of gravitating systems will shed some light on the ways to achieve an ultraviolet complete quantum theory of Gravity, giving us information about fundamental problems of classical Gravity such as the initial big bang singularity, the cosmological constant problem and the physics at the Planck scale. On the other hand, it will give vital information on the early-time inflationary evolution of our Universe. The aim of the 6th Aegean Summer School is to discuss quantum gravity theories in connection with cosmological models and observations, and explore what type of signature modern and mathematically rigorous frameworks can be detected by experiments. It is also aimed at introducing postgraduate students and young researchers to this very challenging topic that recently has attracted much interest.

Various aspects of Quantum Gravity and Quantum Cosmology will be discussed: Quantum Gravity and String Theory, Discretized Gravity, Loop Quantum Gravity, Quantum Criticality in Condensed Matter Physics, Loop Quantum Cosmology, Quantum Gravity Phenomenology, Quantum Gravity and Inflation, Quantum Gravity Constraints on Models of Dark Matter and Dark Energy, Holographic Universe, Asymptotically Safe Quantum Gravity. The invited speakers include: J. Ambjorn, A. Ashtekar, E.A. Bergshoeff, M. Bojowald, R. Brandenberger, S. Liberati, M. Reuter, V. Rivasseau, C. Rovelli, J. Silk, K. S. Stelle, S. Tsujikawa, C. Wetterich, R. P. Woodard.

The school will take place in the School of the Ursulines in Chora of the Naxos island made available to us by the Municipality of Naxos which we gratefully acknowledge.

The morning sessions will consist of mainly review talks on major topics of the field, while in the afternoon sessions short talks will be given on current research topics. Those graduate and postgraduate students interested in attending the school are requested to send a short CV and one recommendation letter to the School's Secretary Ms. Fani Siatra, email: aegean11.sec"AT"gmail.com . Financial support will be provided for a limited number of accepted applicants.

The School is organized and sponsored by the Albert Einstein Institute in Potsdam, the University of Crete , the University of Tennessee and the Physics Department of the National Technical University of Athens, and it is cosponsored by the Municipality of Naxos and the General Secretariat of Aegean and Island Policy.
