Dr. Strathmann’s research focuses on mechanisms controlling the fate of aquatic pollutants in both engineered treatment processes and natural systems, with a special emphasis on reduction-oxidation (redox) processes that are mediated by metal species (e.g., nanophase metal catalysts, dissolved metal complexes, soil minerals). Current research includes the development of advanced water treatment technologies for emerging micropollutants (e.g., pharmaceuticals, hormones, nitrogenous disinfection byproducts) that are more sustainable than current treatment approaches, and the study of subsurface redox processes which contribute to the remediation of persistent contaminants (e.g., explosives, uranium).
