Windows of Susceptibility
August 21, 2017
People can be exposed to a wide variety of chemical and non-chemical stressors in their daily lives. These stressors may come from outdoors, homes or workplaces, food consumption, or use of personal care products. Exposure at low levels may not necessarily be problematic for human health, but researchers are looking at different periods in human growth and development where people may be more sensitive to these exposures. Researchers call these especially sensitive periods “windows of susceptibility.” One window of susceptibility is during pregnancy and early development.
In this podcast, hear how researchers are studying windows of susceptibility throughout the lifespan and learn how to prevent potentially harmful exposures to environmental stressors.
Ami Zota, Sc.D., is an assistant professor in the Department of Environmental & Occupational Health at the George Washington University (GW) Milken School of Public Health. Her research examines exposures to environmental chemicals, their effects on women’s and children’s health, and the implications of these risks for disproportionate health outcomes. She received a K99/R00 career development award from National Institutes of Environmental Health Sciences to identify how environmental hazards may interact with social disadvantage and psychosocial stressors to exacerbate harms during pregnancy.
Zota is committed to developing innovative approaches for science translation so that her research can more effectively be used to inform decision-making at the individual and societal level. Her research has been featured in high-impact national and international media publications including the Washington Post, the LA Times, USA Today, Huffington Post, and the Atlantic Monthly. She has helped shape health and safety standards for flame retardants and other consumer product chemicals by participating in legislative briefings, providing technical assistance to the NGO community, and writing commentaries for popular media.
Before joining GW, Zota studied human exposure and health effects of endocrine-disrupting chemicals at the Silent Spring Institute and then later at the University of California, San Francisco's Program on Reproductive Health and the Environment. She received her masters and doctorate in environmental health at the Harvard School of Public Health.
She is an Associate Editor of Journal of Exposure Science and Environmental Epidemiology and on the Editorial Review Boards of Environmental Epigenetics as well as Environmental Health Perspectives.
