Sarah is a board-certified toxicologist (DABT) and Senior Risk Assessment Scientist with approximately eight years of experience in toxicology, human health risk assessment, exposure assessment, and occupational health. She has a MS in environmental health with a specialty in toxicology from the University of Massachusetts Amherst, and a BS in biology from Saint Michael’s College. Sarah’s work has focused on evaluating potential health risks associated with chemical exposures, including asbestos, nitrosamines, talc, phthalates, parabens, polybrominated diphenyl ethers (PBDEs), flavoring ingredients, and harmful or potentially harmful constituents (HPHCs) in electronic nicotine delivery systems (ENDS) and oral nicotine products. She has conducted human health risk assessments addressing trace nitrosamine contamination in pharmaceutical products, and has advised pharmaceutical companies on the selection of appropriate toxicological comparators for estimating interim Acceptable Intakes (AI) for novel nitrosamines. She is experienced in designing and conducting exposure simulation studies. She has also provided technical support to various manufacturers of alternative tobacco products in their submission of FDA Premarket Tobacco Applications, including evaluation of potential hazards and health effects associated with ENDS and oral nicotine products. Her experience also includes qualitative and quantitative exposure assessments related to occupational, non-occupational, and bystander exposures to asbestos-containing products. In addition, has provided technical support in U.S. and Canadian litigation matters involving asbestos, nitrosamines, and alternative tobacco products.
