My research interests range from wildlife health as affected by environmental contamination and other anthropogenic disturbances, to factors affecting the conservation of wildlife and ecosystems. The majority of my research has involved birds including passerines, waterfowl and gulls, storks, vultures and raptors. Other classes of vertebrates with which I work are amphibians and carnivores. A new area of toxicology that I am investigating is the mitigation of chronic arsenic toxicity (arsenicosis) in mammals using biofortified food. Arsenicosis is estimated to affect 50 to 100 million people worldwide, making it the major global toxicity problem in history. Much of my research occurs through graduate students and spans wide geographic areas including numerous sites across Canada, Spain, Argentina and South Africa. Specific research areas:
- Disease resistance related to exposure to environmental contaminants and immunotoxicity in wild birds
- Developing and validating noninvasive hormonal and disease indicators of health in populations of wild carnivores.
- Mitigating arsenic toxicity in mammals using food naturally biofortified with selenium and folate
- Physiological impacts of oil sands’ mining effluent on raptors, passerines and amphibians.
- Pathological and immunotoxicological impacts of air-borne contaminants on birds of prey.
