Dr. Smith is an ecotoxicologist with broad ranging interests in contaminant exposure and responses among ecological receptors.  His research is focused on pathways of contaminant exposure among mammals, birds, aquatic organisms, and trophic transfer of environmental contaminants. Additionally, physiological and population-level responses to contaminant exposure are of particular interest to Dr. Smith. Dr. Smith’s research is grounded in ecological relevance and is strategically aligned with his academic emphasis which is ecological risk assessment. Dr. Smith received his doctoral degree in environmental toxicology from Texas Tech University in May, 2000, and has since advanced from Senior Research Associate to Associate Professor.  Dr. Smith serves as Vice-Chair of the TTU Institutional Animal Care and Use Committee. He is a reviewer for numerous national and international journals and serves as Associate Editor for Journal of Herpetology and as an editorial board member for Environmental Pollution.
