Dr. Philip N. Smith
Associate Professor, Terrestrial Ecotoxicology
Ph.D. Environmental Toxicology, Texas Tech University 2000
B.S. Chemistry & Biology, Murray State University 1988
Ecological Risk Assessment
ENTX 6371 Ecological Risk Assessment
Dr. Smith is an environmental toxicologist 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 strategically aligned with his academic emphasis which is risk assessment. Dr. Smith serves as Chair of the TTU Institutional Animal Care and Use Committee. He serves as Associate Editor for Environmental Toxicology & Chemistry, Environmental Health Section Editor of Earth Systems and Environmental Sciences, and on the editorial board for Environmental Pollution.
