Health Scientist

Kembra Howdeshell, Ph.D., is a Health Scientist with the Integrated Health Assessment Branch, Division of Translational Toxicology (DTT; formerly Division of the National Toxicology Program) at the National Institute of Environmental Health Sciences. Her research interests include developmental reproductive toxicology, endocrine disruption, and mixtures toxicology. At the DTT, she conducts literature-based evaluations on the health effects of environmental exposures using systematic review methodology. Her research has focused on reproductive toxicity studies of bisphenol A and phthalate mixtures as well as systematic review evaluations on the association of occupational exposure to cancer chemotherapy use and adverse health effects and the association of traffic-related air pollution and hypertensive disorders of pregnancy as well as systematic evidence maps on personal care products and a variety of health outcomes. She collaborated with federal and academic researchers to summarize the published research from the Consortium Linking Academic and Regulatory Insights on BPA Toxicity (CLARITY-BPA), and she led a narrative review on CLARITY-BPA in the context of other BPA publications with suggestions for refining the toxicity testing of potential endocrine disrupting chemicals. Additionally, Howdeshell serves on several DTT, NIEHS, and interagency committees, including DTT's Combined Exposures and Mixtures Program.
