About

Bryn Austin is a Professor of Social and Behavioral Sciences at the Harvard T.H. Chan School of Public Health, Professor of Pediatrics at Harvard Medical School, and Research Faculty in the Division of Adolescent and Young Adult Medicine at Boston Children’s Hospital. She is a social epidemiologist and behavioral scientist, and a unifying goal of her academic career has been to advance innovations in transdisciplinary science applied to eating disorders prevention and the study of health inequities adversely affecting sexual and gender minority youth.

Catherine Berkey has been an investigator with GUTS since its inception in 1996.  She is a biostatistician at Harvard Medical School and Brigham and Women’s Hospital. Dr. Berkey’s current research focuses on the role of factors from birth through adolescence on benign breast disease in young women.

Carlos Camargo, MD, DrPH, has been part of GUTS since the 1990s. He is a Professor of Emergency Medicine and Medicine at Harvard Medical School, Professor of Epidemiology at Harvard T.H. Chan School of Public Health, and the Conn Chair in Emergency Medicine at Massachusetts General Hospital. Dr Camargo’s research focuses on asthma/allergy, alcohol consumption, and vitamin D.

Brittany Charlton, ScD, has been an investigator of GUTS since 2010. She is Assistant Professor at Boston Children’s Hospital, Harvard Medical School, Harvard T.H. Chan School of Public Health, and Brigham and Women’s Hospital. Dr. Charlton’s research focus is to understand the development and prevention of sexual orientation-related disparities in reproductive health.

Dr. Chavarro is the Principal Investigator of GUTS and Nurses’ Health Study 3 (NHS3) and Co-Investigator of the Fathers & Families Substudy. He is Associate Professor of Nutrition and Epidemiology at Harvard T.H. Chan School of Public Health and Associate Professor of Medicine at Harvard Medical School. His research focuses on understanding how nutritional, metabolic, and lifestyle factors impact human reproduction, and how reproductive events and milestones impact other aspects of health throughout the life course and across generations.

Dr. Gaskins is Assistant Professor of Epidemiology at Emory University in Atlanta. Her research focuses on understanding the relation of environmental, dietary, and lifestyle factors with fertility and fecundity in men and women.

Dr. Hart is Scientific Director of GUTS. She is Associate Professor of Medicine at the Channing Division of Network Medicine, Department of Medicine, Brigham and Women’s Hospital and Harvard Medical School and in the Department of Environmental Health at Harvard T.H. Chan School of Public Health. Her research focuses on environmental and occupational risk factors of chronic diseases. She is particularly interested in the effects of air pollution and other environmental exposures. She is a founding member of the Spatial and Contextual Exposomics and Epidemiology Laboratory. She also leads the Reproductive Effects of Chemical and Air Pollution (RECAP) study in GUTS, which examines the impact of air pollution and daily chemical exposures on semen quality.

Peter James is an Assistant Professor in the Department of Environmental Health. His research focuses on estimating the influence of spatial factors, including exposure to nature, the built environment, air pollution, light pollution, noise, and socioeconomic factors, on health behaviors and chronic disease. He is developing methodologies to assess real-time, high spatio-temporal-resolution objective measures of location and behavior by linking smartphone-based global positioning systems (GPS) and consumer wearable device accelerometry data to understand how spatial factors influence health behaviors.

Dr. Laden is co-principal investigator of NHS3. 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.

Eva Schernhammer, MD, DrPH, has been an investigator with GUTS since 2014. She is associated faculty at Harvard Medical School and Harvard T.H. Chan School of Public Health since 2003. Dr. Schernhammer is best known for her studies on disturbances of the circadian clock and their role in human health. She is one of the pioneers of circadian epidemiology and leads a group of scientists at Harvard who study these concepts, using longitudinal population studies including GUTS.
