Biographical Information:

James T. Oris is a Professor of Zoology, the Zoology Graduate Program Director, and the Co-Director of the Center for Environmental Toxicology and Statistics. He is an environmental toxicologist with a primary interest in the fate, dynamics, and toxicity of trace organic contaminants in aquatic organisms.

Dr. Oris' areas of research interest include the photochemistry and toxicology of polycyclic aromatic hydrocarbons in fish, the molecular regulation of the cytochrome P-450 metabolizing system in fish, the fate and dynamics of sediment pollutants in fish and invertebrates, and the modeling and statistical analysis of toxicity dose-response relationships. Dr. Oris has received funding from the U.S. EPA, from NIEHS and from industrial sources to conduct research in these areas. In addition to toxicology research, he is involved in the development of multimedia materials for use in the environmental science classroom.

His laboratory is equipped to conduct aquatic toxicity studies, and includes equipment such as HPLC, GC, and AA instruments for the analysis of organic and inorganic contaminants. He teaches graduate-level courses in the chemical analysis of ecological materials and in environmental toxicology, and an undergraduate course in environmental biology.
