Linda Birnbaum

Linda Birnbaum served as director of NIEHS and the National Toxicology Program, where she shaped the national research agenda on environmental carcinogenesis for over a decade. Her research on dioxins, endocrine disruptors, and PFAS chemicals established critical evidence linking environmental exposures to cancer risk at low doses previously considered safe. Her advocacy for applying the precautionary principle to environmental carcinogens has influenced regulatory policy in the US and internationally.
