Overall, my research program investigates mechanisms underlying toxicity of both natural and anthropogenic toxicants. The ultimate goal of this research is to establish acceptable risk thresholds for toxicants, which can be used by industry or regulatory bodies in efforts to improve environmental quality and animal health.
My research areas include:
- Hormone cross-regulation and disruption of endocrine signaling affecting development and reproduction
- Mechanisms of contaminant-induced immune suppression in fish and amphibians – implications for disease susceptibility
- Effects of dietary mycotoxins on animal performance, focus on immune response, gut health, oxidative stress and organ damage
- Use of genomic and biochemical techniques to identify and evaluate exposure to environmental contaminants
