An essential ingredient for correlated electron materials is to include elements that are favorable for hybridization between localized states and conduction electrons. This is accomplished by investigating materials that include 4f or 5f electron elements with multiple valences (Ce, Pr, Sm, Eu, Tm, Yb, U, Np, and Pu) or d-electron elements with a tendency towards electronic localization (e.g., 1st row transition metals). Electronic correlations may also be enhanced by two dimensional confinement: therefore, layered structures are preferred. We further emphasize that much of our insight into such materials is provided by well-developed tuning studies. As such, it is required to have a strategy for tuning new materials (e.g., using applied pressure, chemical substitution, and magnetic fields). In our research program, we seek to close the loop between these stages of research. In addition to correlated electron systems, we are currently investigating topological states of matter, unconventional superconductivity, and thermoelectric materials - all of which call for individual strategies.
