I am interested in contaminant effects in fish and wildlife, their variation in time and space, their movement through food webs, and how their exposures are influenced by diet and non-chemical threats, such as climate change and invasive species. Accordingly, my research incorporates elements of ecology, ecotoxicology, analytical chemistry, limnology, and public health to provide useful information to managers so that they have a strong scientific basis for making decisions.
