研究领域

Ecotoxicology, Interests include the fate and effects of contaminants in aquatic ecosystems, including stream microcosm toxicity tests using naturally occurring macroinvertebrate and periphyton communities, instream bioassessments of benthic community integrity, and the use of aquatic insect cholinesterase activities as potential biomarkers of organophosphorus pesticide contamination in streams.
