Environmental Toxicology PhD Concentration

ET Description

The Environmental Toxicology Concentration provides both didactic and research training on the fate and effects of pollutants in the environment. Research and training encompasses both human and environmental health consequences of exposure to environmental contaminants. A multidisciplinary approach to research and training are emphasized spanning such areas as mechanisms of toxicity to chemical risk assessment.

If you have questions or would like to arrange a visit to our campus please contact Dr. David Buchwalter, the Coordinator of the Environmental Toxicology Concentration.

ET Research

Students electing the Environmental Toxicology Concentration conduct dissertation research in areas related to the fate and effects of environmental contaminants. Current areas of research include measuring and modeling the fate of chemicals in the environment, bioavailability and bioaccumulation of chemicals in aquatic organisms, effects of pollutants on community structure and ecosystems, and mechanisms and consequences of environmental endocrine disruption in fish, reptiles, and invertebrates. Please visit the research page for more information on research opportunities and faculty research interests.

Current Students and Recent Graduates in ET

The passion for scientific discovery among faculty in Environmental Toxicology is invigorated by the enthusiasm that students bring to scientific inquiry during the course of their PhD program. Listed below are the names of recent graduates of the Environmental Toxicology concentration along with their thesis titles, the laboratories in which they conducted their doctoral research, and their current research positions. You will also find a list of current students their areas of research and the laboratories in which they are studying. Feel free to contact any Environmental Toxicology student for information about their specific research project, their laboratory, or the Environmental Toxicology concentration. Complete contact information for all current students may be found on the People/Studentpage.
