I am an environmental exposure scientist and epidemiologist whose research helps protect reproductive and child health by investigating exposure to contaminants in drinking water, food, consumer and personal care products. Most recently I reported that women with higher exposures to organophosphate flame retardants were less likely to achieve clinical pregnancy or live birth among an IVF clinic population. As animal studies have reported similar findings, this indicates that these flame retardants may be one of many factors contributing to the current infertility epidemic.
I have conducted biomonitoring and health studies for a wide range of populations including infertile couples, pregnant women, infants, new mothers, office workers, gymnasts, and communities exposed to contaminated drinking water. This research has contributed to public health interventions aimed at reducing exposures to flame retardants, perfluoroalkyl substances, and arsenic. Broad implications of my work are the importance of considering multiple exposures, preconception as a sensitive window of development, and the need for improved strategies to avoid regrettable substitution.
