Jong K Keum

Neutron Scattering Scientist

Jong Keum received a Ph. D. degree in Chemistry from the State University of New York (SUNY) at Stony Brook in 2007. After a couple of post-doctoral appointments at the Case Western Reserve University (CWRU) and Oak Ridge National Laboratory (ORNL), he joined Neutron Scattering Division (NSD)/Center for Nanophase Materials Sciences (CNMS), ORNL as a staff member in 2013. Jong’s major research has focused on the nano- and mesoscale structure and physics of soft matters and nanocomposites, where he primarily utilizes X-ray and neutron small-angle X-ray scattering, reflectivity and diffraction.
