Jessie P. Buckley

Jessie P. Buckley is an Associate Professor at the Johns Hopkins University's Department of Environmental Health and Engineering. She is affiliated with the Wendy Klag Center for Autism and Developmental Disabilities and the Environmental influences on Child Health Outcomes (ECHO) Data Analysis Center. Her research focuses on early-life environmental chemical exposures and their impacts on children's health, including asthma, obesity, and developmental disorders. Dr. Buckley holds a PhD from the University of North Carolina at Chapel Hill (2014), an MPH from George Washington University (2007), and an AB from Bowdoin College (2002).

Her work integrates epidemiologic methods with exposure assessment, examining chemical mixtures such as phthalates, PFAS, and organophosphate esters. Key themes include understanding how prenatal and childhood exposures to endocrine disruptors influence growth, metabolic health, and neurodevelopment. She has led studies on the health implications of ultra-processed food consumption and environmental pollutants in vulnerable populations.

Publications highlight her contributions to understanding preterm birth disparities linked to phthalate exposure, the role of environmental exposures in pediatric asthma, and the application of statistical methods like item response theory to analyze chemical mixture effects. Collaborations span institutions including the NIH's ECHO Program and international cohorts in Bangladesh.

Dr. Buckley's research has informed policy discussions on reducing chemical exposure risks, particularly for pregnant women and children. She advises on environmental health projects and mentors teams exploring innovative approaches to exposure burden measurement. Current initiatives focus on longitudinal studies of chemical mixtures and their interactions with genetic and social factors.
