Rachel Morello-Frosch is a professor at UC Berkeley’s School of Public Health whose research integrates community-based and environmental health science methods to understand structural determinants of environmental health among diverse communities with a focus on social inequality, racism, discrimination, psychosocial stress, and how these factors interact with environmental hazard exposures to produce health inequalities. She also collaborates with environmental justice partners to develop tools to improve policy and regulatory decision-making, and to advance environmental justice.
