Professional Experience

Dr. McCall is the Deputy Magnet Thrust Lead for the Critical Materials Institute, Group Leader of the Actinides and Lanthanides Science Group, and Deputy Associate Program Lead for Met. and Mater. Characterization. He is a member of the team that won establishment of the Critical Materials Institute, a DOE Innovation Hub (2013). He leads the effort to develop exchange spring magnets with advanced manufacturing. Dr. McCall established a physical properties measurement laboratory and developed capabilities for work on small samples of plutonium and other actinides, and built a high-temperature synthesis laboratory for work with 4f and 5f (through U) alloys. Since 2010, he has been co-lead of the U.S. delegation (LLNL and LANL) for US–Russian workshops on Fundamentals of Plutonium and program chair for Pu Futures—The Science 2014 (premier international conference on Pu, held in alternate years). He has conducted research into the Ruddlesden-Popper series of ruthenates—(Ca,Sr)_n+1Ru_nO_3n+1—one of nature’s multilayer systems (n = # of RuO₆ layers) that demonstrate emergent behavior, including quantum criticality, superconductivity, ferromagnetism, antiferromagnetism, and exotic magnetic states.
