This manuscript reviews recent applications of the nuclear shell-model for the calculation of several quantities relevant for the core-collapse supernova dynamics and nucleosynthesis. These include electron capture rates and neutrino-nucleus cross sections for inelastic scattering. It is shown that electron capture rates on nuclei dominates over capture on free protons during the collapse leading to significant changes in the hydrodynamics of core collapse and bounce. Neutrino-nucleus cross sections at supernova neutrino energies can be determined from precise data on the magnetic dipole strength. The results agree well with large-scale shell-model calculations, validating this model.
