Dr. Halbrook is a wildlife toxicologist in the Cooperative Wildlife Research Laboratory and Associate Professor in the Department of Zoology, Southern Illinois University. His research interests include the design, implementation, and validation of biomarker-based biomonitoring capabilities, the application of wildlife toxicological methods in ecological risk assessments and the development and validation of biomarkers of contaminant exposure and effects in wild species. Dr. Halbrook has used wildlife toxicological methods to study effects of environmental contaminants on river otter and muskrat populations and has used great blue heron and mink in ecological risk assessment and monitoring during environmental remedial investigations. He teaches an undergraduate course in wildlife techniques and a graduate course in wildlife toxicology.
