Brief synopsis of current research:
My research centers on aquatic environmental toxicology with particular interest in environmental risk assessment. I have undertaken work mainly in the area of fisheries, and have worked with most groups of troublesome environmental contaminants includiing metals, PCBs, PAHs, dioxins, furans, cyanides, ammonia, and pulp mill effluent to name a few.
