Bio:

Dr. Smith is an environmental toxicologist whose research examines pathways of contaminant exposure and physiological and population-level responses of ecological receptors following exposure to environmental contaminants. Dr. Smith’s research is strategically aligned with his academic emphasis which is ecological risk assessment. Dr. Smith serves as chair of the TTU Institutional Animal Care and Use Committee. He is an editor of the international scientific journal Environmental Pollution, and associate editor of Environmental Toxicology & Chemistry.
