Germaine Louis, PhD, MS

Dean, College of Health and Human Services

Dr. Germaine Louis is an internationally recognized reproductive and perinatal epidemiologist whose expertise focuses on the impact of environmental influences on human fecundity and fertility. Her research has addressed a mixture of environmental exposures, including endocrine disruptors, stress, diet, and physical activity in relation to a spectrum of reproductive outcomes in both men and women. In addition, Dr. Louis’ research extends to studies of the implications of fecundity and fertility for health across the lifespan and future generations. A complimentary and parallel avenue of research includes methods aimed at addressing challenges, such as the complexity associated with studying exposure mixtures and studying reproductive potential outcomes that often are not statistically independent or may be blocked by an intervening event. She was an early pioneer in the application of the exposome research paradigm for understanding environmental influences on human fecundity and fertility impairments. She has served as Principal Investigator for original extramural and intramural research totaling over $53 million.
