Biography

Bumjoon (“BJ”) Kim is a staff scientist in the Material Science Division. He received B. A. from Korea Advanced Institute of Science and Technology in 1999 and Ph. D. from Seoul National University in 2005. His thesis involved angle-resolved photoemission (ARPES) studies of transition-metal oxides. Before joining MSD in 2010, he held postdoctoral position in University of Michigan and visiting assistant professor in University of Tokyo. His current research focuses on 5d transition-metal oxides, in which strong spin-orbit coupling and correlation effects conspire to realize novel phases of matter. His research program encompasses single crystal growth and characterizations, elastic and inelastic x-ray scattering, and ARPES.
