Research Profile
My interests and research include exposure modeling and refinement of exposure estimates for use in risk assessment. The University of Florida’s Center for Environmental and Human Toxicology holds the singular contract for the Florida Department of Environmental Protection (FDEP) to provide technical reviews of risk assessments for the State of Florida. Over past years we have produced hundreds of these technical reviews advising the FDEP on all aspects of risk assessment and have created exposure models for seafood consumption for high-end consumers on the Gulf of Mexico, irrigation of vegetable gardens and ornamental beds, and swimmers in creeks and the ocean. Our recent work includes an NIH grant to generate a threshold dose for memory impairment from long term exposure to domoic acid in clams. Additionally, we are currently working with the FDEP to develop screening criteria for perfluoroalkyl substances in surface water that are protective of human and ecological health.
