About Ananya Roy

Ananya Roy

Senior Health Scientist


Areas of expertise:

Air quality, lead, cardiovascular disease, neurodevelopment


Ananya is an Environmental Epidemiologist with expertise in the health effects of air pollution and lead exposure. Her role at EDF is to provide balanced scientific evidence to inform policy and advocacy efforts to protect children, disadvantaged communities and other vulnerable populations from exposures that are harmful to their health and wellbeing.

She currently leads research on the health effects of ambient air pollution within neighborhoods and children’s exposures to lead from paint and lead service lines.


Before EDF, Ananya was a research faculty at Yale School of Public Health and Environmental and Occupational Health Sciences Institute, NJ, where her work encompassed the effect of ambient and indoor air pollution on children’s lung growth and cardiopulmonary effects, intergenerational transfer of lead, effects on neurodevelopment and associated genetic and nutritional susceptibility. She has also published on the neurodegenerative effects of persistent organic pesticides. Most of Ananya’s work has been carried out in India and China.
