Kee Sung Han received his B.S. in Physics from Andong National University, Andong, Korea in 1998 and Ph.D. in Physics from Konkuk University, Seoul, Korea in 2006. He did his postdoctoral studies at Korea Basic Science Institute and Oak Ridge National Laboratory specializing in nuclear magnetic resonance (NMR) spectroscopy. He joined PNNL as a postdoctoral researcher in 2013 and converted to senior scientist in 2016. His current research is focused on understanding electrochemical materials and phenomena in batteries and fuel cells using in-situ and ex-situ NMR techniques including pulsed field gradient (PFG) NMR. He is also interested in NMR applications to materials sciences especially in understanding interfacial interactions, structures, and dynamics.
