Biography

Dr. Carolyn Pearce joined the Geosciences Group at PNNL in 2016 and works on the characterization of minerals relevant to radioactive waste storage and processing in order to determine reaction mechanisms and kinetics that affect radionuclide stability in waste forms and subsurface environments. Dr. Pearce is also a visiting academic in the Department of Crop and Soil Sciences, Washington State University, and the School of Earth and Environmental Sciences at the University of Manchester, United Kingdom.
