Richard T. Di Giulio Richard T. Di Giulio is Professor of Environmental Toxicology in the Nicholas School of the Environment at Duke University. At Duke, he also serves as Director of the Integrated Toxicology and Environmental Health Program, Director of the Superfund Basic Research Center, Director of the Center on Environmental Health, Policy and Disease Vulnerability, and Co-Principal Investigator for the Center for the Environmental Implications of Nanotechnology. He received a B.A. in comparative literature from the University of Texas at Austin, the M.S. in wildlife biology from Louisiana State University and his Ph.D. in environmental toxicology from Virginia Polytechnic Institute and State University. Dr. Di Giulio has published extensively on subjects including biochemical and molecular mechanisms of adaptation and toxicity, biomarkers for chemical exposure and toxicity, effects of chemical mixtures, and chemical contamination of sediments. His current work focuses on mechanisms by which polycyclic aromatic hydrocarbons (PAHs) and nanomaterials perturb embryonic development in fish models (zebrafish and killifish), the evolutionary consequences of hydrocarbon pollution on fish populations, and the ecological and health impacts of mountaintop coal mining. Additionally, he has organized symposia and workshops, and written on, the broader subject of interconnections between human health and ecological integrity. Dr. Di Giulio serves as an advisor for the Scientific Advisory Board of the U.S. EPA, is a member of the Computational Toxicology Committee for the Board of Scientific Counselors, U.S. EPA, a member of the National Academy of Science Committee on Exposure Assessment in the 21st Century, and is associate editor for Environmental Health Perspectives.
