Ab-initio calculations--starting from the sole knowledge of a realistic nuclear force--aim at eventually achieving parameter-free predictions of nuclear properties. These pose strong requirements on quantum many-body theory. Recent breakthroughs in the theory of nuclear interactions and computational many-body physics have opened the way to unprecedented studies of closed-shell nuclei in the medium mass region. In these cases, ground state and spectroscopic properties can now be calculated up to masses of A=56. However, closed shells represent just a small fraction of the exotic isotopes available in Nature. New developments (based on calculations of Gorkov-Green's functions and self-energies)  will allow to push back current limitations in two main frontiers: open-shell systems and reactions.
