Professor, UC Berkeley School of Public Health and Department of Environmental Science, Policy and
Rachel Morello-Frosch is an environmental health scientist whose research examines the combined
effects of environmental chemicals and chronic stress on human health. Much of her work has
examined this environmental justice question by using community-based participatory research
approaches for data collection and risk communication. In collaboration with advocates, scientific
colleagues, and regulatory scientists, she has worked to develop scientifically valid and transparent tools
for assessing the cumulative impacts of chemical and non-chemical stressors to improve regulatory
decision-making and policy in ways that protect community health and advance environmental justice.
