Investigators

Dr. Chavarro has been the principal investigator of NHS3 since its founding in 2010. He is Associate Professor of Nutrition and Epidemiology at Harvard T.H. Chan School of Public Health.

Dr. Laden is Professor of Environmental Epidemiology and Associate Chair of the Department of Environmental Health at Harvard T.H. Chan School of Public Health, and Associate Professor of Medicine at Harvard Medical School and Brigham and Women’s Hospital. Her research interests focus on the impact of multiple environmental exposures on the risk of chronic diseases and health outcomes.

Dr. Hart is an Associate Professor of Medicine, Channing Division of Network Medicine, Brigham and Women’s Hospital and Harvard Medical School, and Department of Environmental Health, Harvard T.H. Chan School of Public Health. Her work focuses on the impact of multiple environmental exposures on disease risk. She is Scientific Director of the Growing Up Today Study and leads the Reproductive Effects of Chemical and Air Pollution (RECAP) research project in GUTS, examining the impact of air pollution and daily chemical exposures on semen quality.

Dr. Brittany Charlton is an Associate Professor at Harvard Medical School and the Harvard Pilgrim Health Care Institute in the Department of Population Medicine and at the Harvard T.H. Chan School of Public Health in the Department of Epidemiology. The focus of Dr. Charlton's research is on health inequities among sexual and gender minorities—particularly related to reproductive health and cancer. The second focal area of her research is contraception use and family planning among people of all sexual orientations and gender identities.

Dr. Gaskins is an Associate Professor in the Department of Epidemiology at the Emory University Rollins School of Public Health. Her research focuses on understanding the relation of environmental, dietary, and lifestyle factors with reproductive health in men and women.

Dr. Rich-Edwards is Director of Developmental Epidemiology at the Connors Center for Women’s Health and Gender Biology at Brigham and Women's Hospital, Associate Professor of Medicine at Harvard Medical School, and Associate Professor of Epidemiology at Harvard T.H. Chan School of Public Health.

Dr. James is an Associate Professor in the Department of Public Health Sciences at the University of California Davis School of Medicine, as well as an Associate Professor at Harvard TH Chan School of Public Health. Trained in environmental health and epidemiology, Dr. James' research focuses on estimating the influence of spatial factors, including exposure to nature, the built environment, the food environment, air pollution, light pollution, noise, and socioeconomic factors, on health behaviors, mental health, cognitive function, and chronic disease. He leads the Built Environment Assessment through Computer VisiON (BEACON) project in the Nurses' Health Study 3, where he uses deep learning algorithms, Google Street View images, smartphone GPS, and wearable devices to examine built and natural environment influences on health behaviors and cardiovascular disease risk.

Dr. Weisskopf is the Cecil K. and Philip Drinker Professor of Environmental Epidemiology and Physiology at the Harvard T.H. Chan School of Public Health in the Departments of Environmental Health and Epidemiology, and Director of the Harvard TH Chan NIEHS Center for Environmental Health. His work focuses on the influence of environmental exposures on brain health across the life course, in particular neurodevelopmental outcomes such as autism spectrum disorders and attention deficit-hyperactivity disorder. Dr. Weisskopf also works on epidemiological methods issues to improve causal inference from observational environmental health studies.

Dr. Adrienne Martinez-Hollingsworth, PhD, RN, PHN is a health disparities researcher exploring the impact of provider wellbeing on the delivery of chronic illness care and treatment uptake in the safety net. Her interventions use public art and community-based work groups that promote empathy and trust-building between historically underrepresented patients and providers. Currently, she is the Manager of Clinical Education at Gateways Hospital and Mental Health Centers in Los Angeles, CA.
