Strongly correlated electron materials, pose great conceptual and computational challenges. Quantum embedding methods such as Dynamical Mean Field Theory (DMFT) has enabled a community of scientists to achieve great progress in this area. We will review some basic ideas underlying this approach, such as the reduction of the full many body problem into a quantum impurity model satisfying a self consistency condition. We will then provide examples of some progress using materials containing elements from different regions of the periodic table, outlining different classes of strongly correlated behavior: heavy fermions, Mott systems and Hund metals. We will conclude with the great challenges ahead.
