Tracy K. Collier
NOAA Fisheries, USA

Tracy K. Collier supervises a research enterprise comprised of approximately 90 scientists as a Director of the Environmental Conservation Division of NOAA’s Northwest Fisheries Science Center. The Division contains four research programs, namely, watershed processes, ecotoxicology, environmental chemistry, and marine biotoxins. Dr. Collier is responsible for the overall science direction and quality. His research interests over the years have covered some of the first work on metabolism of PAHs by fish, studies of the impacts of oil spills on marine fish and mammals, the enzymology of carcinogen activation and detoxication, and assessing overall effects of contaminants on fish populations through the use of field investigations. His current personal research interests are in the areas of environmental toxicology, field investigations of causality, the use of marine mammals and fish as sentinel species for assessing relationships between oceans and human health, and the ecological consequences resulting from exposure to “sublethal” levels of chemical contaminants. He is a Postdoctoral Advisor to the National Research Council, and serves on a number of regional, national, and international panels and committees. He has authored or coauthored approximately 120 scientific publications.
