Jennifer L. Freeman is an Associate Professor in the School of Health Sciences at Purdue University in West Lafayette, IN. She received a B.S. in Cell and Structural Biology from the University of Illinois at Urbana-Champaign and a Ph.D. in Environmental Toxicology and Molecular Cytogenetics from the University of Illinois at Urbana-Champaign. She did her post-doctoral work at Harvard Medical School and Brigham and Women’s Hospital, Boston. The interests of the Freeman laboratory are to define the underlying genetic and epigenetic mechanisms of toxicity of environmental stressors with current focus on pesticides, metals, radiation, and emerging contaminants. Projects are defining the immediate adverse impacts of a developmental exposure, the lasting adverse impacts of this developmental exposure throughout the lifespan, and the analysis of subsequent generations linking genetic, epigenetic, and phenotypic assessments. These studies are investigating the developmental origin of health and disease pathogenesis with a specific focus on neurological disorders, reproductive dysfunction, cardiovascular function, and cancer with a goal of understanding the role of exposure to the environmental stressors in these adverse health outcomes. All projects are currently utilizing the zebrafish vertebrate model system as a tool to investigate toxicity.
