Rachel Keith is an Assistant professor of medicine with the division of environmental health and the director of human subject services with the Envirome Institute at the University of Louisville. Her research program combines her diverse skill set in basic sciences, nursing, and clinical studies. While she practices part time in a preventive cardiology clinic, her main focus is researching how environmental exposures impact health outcomes, targeting prevention of cardiovascular disease and novel identifiers of early disease. The environment can be made up of many things including lifestyle choices such as physical activity, tobacco use, and diet choices as well as exposure to toxic compounds such as air pollution. Though genetics plays a role in susceptibility of individuals to disease, a larger portion likely comes from the environment. Her research uses tools for evaluating perceptions of health, cardiovascular health, metabolic health, exposure to hazardous chemicals, greenness exposure, e-cigarettes, and biomarkers of injury. She has participated and managed numerous clinical trials and NIH or industry sponsored investigator initiated human studies, as well including enrolling over 1500 local participants in environmental studies. Establishing how the environment influences both disease and the perceptions of risk has many policy and regulatory implications. Rachel received a B.A., B.S.N., M.S., M.S.N. and Ph.D. from the University of Louisville. She is a board certified Adult nurse practitioner with post-graduate training as a tobacco regulatory fellow with the American Heart Association and a certified tobacco treatment specialist.
