I am an environmental epidemiologist interested in how the environment affects our health, with particular focus on how to characterize the relevant exposure. I joined the faculty of NC State in August 2013 as part of the Chancellor’s Faculty of Excellence Program hires in Environmental Health Sciences. Before that, I was a researcher at the National Institute of Environmental Health Sciences for almost 15 years involved in the Agricultural Health Study, a prospective cohort study of ~60,000 farmers and 32,000 spouses from Iowa and North Carolina. Currently I’m studying how pesticides and phthalates influence respiratory and allergic disease in a number of populations.
Currently, I am principal investigator of the GenX Exposure Study. We’re responding to community questions about GenX in drinking water and the impact of GenX and related per- and poly fluoroalkylated substances (PFAS) on human health. We collected data in Wilmington, NC, in November 2017 and May 2018. We are gearing up for data collection in Fayetteville, NC.
I am working with Dr. Berna van Wendel de Joode of the Universidad Nacional in Heredia, Costa Rica, on a study of women and children living in the banana growing region of Costa Rica where pesticide exposure is common. We are looking at respiratory and allergic impacts of pesticides as well as neurobehavioral and development outcomes in children. We recently received a grant to follow these women and children for another five years.
At NC State, I am the deputy director of the Center for Human Health and the Environment. I have adjunct appointments at the University of North Carolina, Chapel Hill in the Department of Epidemiology and at the East Carolina University Brody School of Medicine.
I received my BS in Environmental Toxicology from the University of California, Davis and my masters and doctorate from the Harvard School of Public Health in Environmental Health and Epidemiology. After a brief post-doctoral fellowship at Harvard, I joined the faculty of the Rollins School of Public Health at Emory University before coming to NIEHS in 1999.
Among my professional activities, I serve as an Associate Editor at Environmental Health Perspectives and PLOS One and am a member of the International Society of Environmental Epidemiology, International Society of Exposure Science, and the American Thoracic Society.
