Biographical Info

Biography
Dr. Rivera-Núñez holds a BS in Microbiology and a MS in Environmental Health Sciences from the University of Puerto Rico. Her doctoral degree is from the University of Michigan in Ann Arbor, MI. She completed a National Academies post-doctoral fellowships at the U.S. Environmental Protection Agency in Cincinnati, OH. Before coming to Rutgers she was on the faculty at Washington University in St. Louis, Brown School, Public Health Program.

Research Areas
Dr. Rivera-Núñez studies chemical exposures and its effects in early life and subsequent health. Most of her research focuses on: (1) effect of measurement error characterizing environmental exposure, (2) the utility of biomarkers identifying windows of exposure and susceptibility, and (3) the effect of perinatal exposures in birth outcomes and children’s development.

Dr. Rivera-Núñez is interested in exposure assessment of endocrine disruptors (EDCs) during pregnancy and early life. Pregnancy/birth studies harbors specific challenges due to the physiological and behavioral factors that may come into play during pregnancy. For example, pregnant women have a weakened immune system and higher water or food intake. Zearalenone (ZEN) and a-zearalanol (ZER) are estrogenic mycotoxins produced by Fusarium fungi. They bind to estrogen receptors alpha and beta with higher affinity than other well-studied EDCs (such as DDT and BPA), and exhibit higher estrogenic potency than genistein and other isoflavones. Although, ZEN and ZER can be detected in a wide range of food products including cereal grains, meat, milk, wine, beer, dried fruit, and spices, there is an absence of reliable human data on excretion rates, dose-response, and impact of age and gender among other important factors and modifiers. Dr. Rivera-Núñez and colleagues are characterizing ZEN and ZER exposure and identify dietary sources of ZEN and ZER during pregnancy.

Another area of research for Dr. Rivera-Núñez is exposure assessment of drinking water contaminants. Her postdoctoral work documented the change in drinking water disinfection treatment from chlorination to chloramination in the United States drinking water systems and their impact in pregnancy outcomes. They have examined this change by linking more than ten years of birth data to drinking water quality data. These publications described how to minimize exposure misclassification from environmental missing data, chemical mixtures, and short windows of exposure. This work is integral part of the U.S. Environmental Protection Agency’s current Stage 2 Disinfectants and Disinfection Byproducts rule revision. Dr. Rivera-Núñez is also interested in toxic metals and maternal health in general.
