I will give an overview of the challenges that modern electronic structure theory faces in describing strongly correlated chemical systems from molecules to periodic systems. Our latest progress in combining density matrix renormalization group with pair-density functional theory [1] as a new way to calculate correlation energy will be discussed, together with the recent development of density matrix embedding methods based on multireference solvers for molecules [2] and materials [3]. Applications to compounds containing transition metals and excited states will be presented.
