I'm Pat Shea, professor of xenobiotic chemistry and toxicology at the UNL School of Natural Resources (SNR). I hold courtesy appointments in the UNL Department of Agronomy and Horticulture, and the Department of Environmental, Agricultural and Occupational Health (EAOH) at the University of Nebraska Medical Center. My interests include protection and management of natural resources and ecosystems, ecological and environmental toxicology, chemicals in agricultural production systems, remediation and restoration of contaminated environments, and protection of public health.
What are xenobiotics? Xenobiotics are biologically foreign substances that did not exist in nature before being synthesized by humans. These substances often become environmental contaminants. Our research encompasses adsorption-desorption, transformation, transport, bioavailability and toxicology of herbicides and other pesticides, munitions, pharmaceuticals, solvents and petroleum products, and heavy metals in water and soil.
We've also conducted research in the remediation of contaminated water and soil, including abiotic and biotic treatment processes. In addition, we've been involved in the development of process-based models, to assess landscape vulnerability to agrichemical leaching and runoff. Much of my research is interdisciplinary and involves collaborations with other faculty members.
I've taught, team-taught and assisted in courses concerning the fate and impacts of xenobiotics in soil, water, and biota; a graduate seminar in environmental health, occupational health and toxicology; and a graduate writing seminar. I've advised or co-advised master's and doctoral students with majors in natural resource sciences, agronomy and toxicology; supervised postdoctoral associates; and hosted visiting scientists. I hold a partial extension appointment and contribute to outreach education programs.
I've been at UNL since completing a Ph.D. in 1981 at North Carolina State University, with a focus on agricultural and environmental chemistry in soil-water-plant systems. I also have a master's in plant science (agricultural management systems) from the University of Connecticut and a bachelor's in biology (general and premedical) from Fordham University in New York City.
In addition to my academic appointments, I'm a member of the intercampus Center for Environmental Health and Toxicology (CEHT), and an affiliate of the Nebraska Water Center, Center for Biotechnology, and the Environmental Engineering Program. I previously served as associate director and research coordinator for SNR, vice chair of the EAOH at UNMC, interim co-director of the CEHT, and have served multiple terms as senator and secretary of the UNL Faculty Senate.
