Abstract	Abstract: Extended Theories of Gravity can be considered as a new paradigm to cure shortcomings of General Relativity at infrared and ultraviolet scales. They are an approach that, by preserving the undoubtedly positive results of Einstein’s theory, is aimed to address conceptual and experimental problems recently emerged in astrophysics, cosmology and High Energy Physics. In particular, the goal is to encompass, in a self-consistent scheme, problems like inflation, dark energy, dark matter, large scale structure and, first of all, to give at least an effective description of Quantum Gravity. In this seminar I will discuss a particular extension of f(R) gravity where also the Gauss-Bonnet topological invariant is considered into dynamics. This approach allows to bypass some of the shortcomings related to the original f(R) gravity and to regularize the theory at astrophysical and cosmological scales
