Dr. Powell’s major teaching and research interests are in the fields of environmental radiochemistry, actinide chemistry, geochemistry, geochemical reaction modeling, and contaminant fate and transport. Dr. Powell’s current research focuses on actinide interactions with natural soils and synthetic minerals through surface complexation modeling and determination of sorption/desorption and oxidation/reduction rates. He teaches courses in environmental radiation measurements, environmental actinide chemistry, and geochemical reaction modeling.
