My research exploits the complementary aspects of the epidemiological, toxicological, and environmental sciences to develop and refine quantitative risk assessment methods to improve the public’s health. The new concepts of cumulative risk assessment present an opportunity to create interdisciplinary approaches to public and environmental health because of the multiple determinants of health framework that serves as its foundation. My work addresses the health effects of exposure to chemical mixtures including whether differential exposure to mixtures contributes to racial and ethnic health disparities. Current US environmental policies address one chemical at a time while actual exposures occur as multiple chemical mixtures. Through my research I seek to inform environmental policies that account for multiple chemical and non chemical exposures.
