One aspect of my research centers on understanding the effects of endocrine disrupting chemicals on nervous system function during development and aging, two periods when the nervous system is particularly vulnerable to toxic insult. My approach includes laboratory-based animal studies and parallel epidemiological studies. Currently we are recruiting a pregnancy cohort of 600 women and following their infants prospectively from birth to assess the impact of prenatal exposures to endocrine disrupting chemicals found in consumer products on early neurodevelopment. One aspect of my laboratory animal research program is mechanistically based, focusing on understanding the specific functional domains that are altered or impaired by these chemicals and the biological mechanisms underlying those impairments. Another aspect is risk-based, modeling actual human exposure to endocrine disruptors and documenting what neurobehavioral outcomes that are affected. Another aspect of my program focuses on assessing the impact of dietary estrogens on cognitive function during aging. Specifically we are using animal models to assess the effects of estrogenic dietary supplements on cognitive functions as well as the underlying mechanisms for these effects.
