David Bellinger

David Bellinger is a Professor in the Department of Environmental Health at the Harvard T.H. Chan School of Public Health and a researcher at Boston Children's Hospital. His work bridges pediatric neurology, environmental epidemiology, and public health, with a focus on early-life exposures and neurodevelopmental outcomes.

Education:

• PhD in Psychology, Cornell University
• Master’s in Epidemiology, Harvard School of Public Health

Dr. Bellinger’s research investigates the impact of chemical exposures (e.g., lead, mercury, arsenic, manganese, pesticides, air pollution) and medical conditions (e.g., congenital heart disease) on children’s cognitive and behavioral development. He employs advanced statistical methods, including structural equation modeling, meta-regression, and causal mediation analysis, to assess complex exposure mixtures and neurodevelopmental trajectories. His recent work emphasizes sensitive windows of exposure, socioeconomic modifiers, and long-term outcomes in vulnerable populations.

His publications from 2023–2025 span high-impact journals such as The New England Journal of Medicine, JAMA Network Open, and Environmental Health Perspectives, with recurring themes in environmental neurotoxicity, congenital heart disease, and developmental epidemiology. He leads or contributes to major cohort studies including Project Viva, BCAS-Adult, and UGAAR.

Scientific Leadership:

• President, International Society for Children's Health and the Environment

Dr. Bellinger has been instrumental in shaping public health policy on lead poisoning prevention and environmental risk assessment. He mentors students and collaborates extensively across disciplines, contributing to clinical guidelines and global burden of disease studies. His work integrates neuroimaging, biomonitoring, and longitudinal behavioral assessments to understand the lifelong implications of early insults to the developing brain.
