Toxicology

Toxicologists study the dose-dependent fate of poisons, natural and synthetic, from source to affected organisms in the environment.

Our research focuses on analysis, metabolism, and mechanistic interactions of modern systemic and seed-treatment pesticides used in transgenic technologies, and their risks to food security, bee pollinators, and other nontarget species.
