Registered Nurse

Rachel Keith, Ph.D., APRN, ANP-C is an Associate Professor of Medicine at the University of Louisville School of Medicine and Director of Human Subject Services at the Environment Institute. As a regulatory trained clinician scientist, Dr. Keith combines her diverse skill set in basic sciences, nursing, community participatory research and clinical studies to understand how environmental exposures impact health outcomes, targeting prevention of cardiovascular disease and novel identifiers of early disease. Though genetics plays a role in susceptibility of individuals to disease, a larger portion likely comes from the environment, which can range from lifestyle choices such as physical activity and tobacco use to inhaled compounds such as air pollution or biotics like Sars-CoV02. Her research, including oversight of numerous clinical studies, seeks to establish how the environment influences both disease and the perception of risk, which has many policy and regulatory implications.
