Bio
Ke Yuan is an R&D Research Associate in the Geochemistry and Interfacial Sciences Group at Oak Ridge National Laboratory. Since completing his Ph.D. in earth and environmental sciences at the University of Michigan in 2015, he was a postdoctoral researcher in the Interfacial Processes Group at Argonne National Laboratory before joining ORNL. His research focuses on revealing the molecular scale mechanisms of geochemical reactions occurring at mineral-water interfaces by using both experimental and computational methods. His current research interests include heterogeneous nucleation, proton transfer reaction, ion adsorption, and ion pairing by using synchrotron-based X-ray nanotomography, coherent X-ray scattering, and rare-event molecular dynamics simulations.
