Birgit G. Claus Henn, ScD

Associate Professor, Environmental Health - Boston University School of Public Health


Birgit Claus Henn is an environmental epidemiologist who seeks to define the impacts of environmental exposures on maternal and child health. Her research focuses on chemical mixtures and their effects on child growth, neurodevelopment, and the health of pregnant and reproductive-aged women. She has examined exposure to metals, pesticides, and endocrine disrupting chemicals and associations with neurodevelopment in multiple pediatric cohorts worldwide, spanning critical periods of development from the prenatal period through adolescence. A central component of her work is estimating health effects of environmental mixtures using state-of-the-art statistical approaches.

Other research interests include the development and use of novel exposure science methods to incorporate exposure timing in epidemiologic studies, and the role of nutritional, social, and other factors in modifying and/or mediating chemical toxicity.

Dr. Claus Henn was the PI of an NIEHS K99/R00 Career Development Award to utilize novel statistical approaches for analyzing metal mixtures and neurodevelopment and is the MPI or co-investigator on multiple NIH R01s on environmental mixtures. She is also the PI of an NIEHS T32 Predoctoral Training Program and serves as the director of the PhD program in Environmental Health at BUSPH.
