Current and Recent Research Projects

My research focuses on quantifying and modeling sediment physicochemical factors that influence the bioavailability, and hence toxicity, of sediment-associated uranium to a model freshwater benthic invertebrate (Chironomus dilutus). Results from this work will help improve risk assessments, environmental regulations and management of uranium concentrations downstream of uranium operations in northern Saskatchewan.
