Profile
Research/Clinical Interests
My focus is veterinary clinical and diagnostic toxicology. Areas of interest within clinical and diagnostic toxicology include wildlife toxicology, development of biomarkers of exposure to environmental contaminants and, more recently, issues related to the safety of foods and feeds (both human and animal) from a chemical contamination perspective.
