Dr. Dickson is an environmental soil chemist and mineralogist with expertise in low-temperature geochemistry, mineralogy, contaminants’ remediation and material science. His scholarly work encompasses the use of field- and laboratory-based and spectroscopy approaches to address complex environmental problems related to safe disposition of nuclear waste and remediation of contaminated subsurface (soil, water and groundwater). Dr. Dickson’s research interests span the fundamental understanding of biogeochemical cycling of nutrients, contaminants, heavy metals and radionuclide in natural and engineered porous media. Dr. Dickson previously worked at Oak Ridge National Laboratory and Savannah River National Laboratory in the interface of contaminant immobilization/remediation, reactive transport modeling, and the coupling of characterization and remedial technologies to meet site-specific cleanup goals
