Professor of Epidemiology, Director of the Center for Climate, Environment & Health

Overview

I am a Professor in the Department of Epidemiology at the Brown University School of Public Health. My career in public health began as an intern in the Milwaukee Health Department Childhood Lead Poisoning Prevention Program and then a school nurse in Milwaukee, WI. I received my master's and doctoral degrees in Epidemiology from the University of North Carolina-Chapel Hill. and completed postdoctoral training in environmental health at the Harvard School of Public Health.

My research foci center around the determinants, health effects, and mechanisms of environmental toxicants in vulnerable populations, including pregnant women, infants, children, and adolescents. This has included extensive work documenting the neurotoxicity of lead (Pb) and endocrine disruptors like BPA, phthalates, and triclosan. For the past 10 years, I have been studying whether early life PFAS exposure increases the risk of later life disease. This includes using high dimensional biomarkers to identify biological pathways underlying these associations. Finally, I have been involved in or led experimental studies to reduce exposure to environmental toxicants and associated health effects.

Our team uses data from several prospective cohort studies in North America (HOME, MIREC, PEACE, and NEFS) to conduct these studies. These cohorts have been following children since before conception or during pregnancy; follow-up now continues as children transition into adolescence. In the New England Family Study (NEFS), we are examining if prenatal PFAS exposure is associated with mid-adulthood chronic disease using a cohort of individuals followed from the 1960s.

Finally, I have dabbled in studying the effects of air pollution and climate change on human performance using publicly available marathon performance data. This work combines my passions for big data, environmental epidemiology, and endurance sports.
