Dr. Germaine M. Buck Louis is an internationally recognized reproductive and perinatal epidemiologist whose expertise focuses on environmental influences on human fecundity and fertility.  Her research has focused on a mixture of environmental exposures, including endocrine disrupting chemicals, stress and lifestyle in relation to a spectrum of reproductive outcomes in both men and women.  In addition, Dr. Buck Louis’ research continues to focus on the implications of fecundity and fertility for health across the lifespan.  A complimentary and parallel avenue of research includes methods aimed at addressing challenges, such as the complexity associated with studying environmental mixtures and the clustering of reproductive outcomes.  She is an early pioneer in the application of the exposome research paradigm for understanding environmental influences on human fecundity and fertility impairments.  During her career, she has served as Principal Investigator for original extramural and intramural research totally over $53 million.

Prior to becoming the Dean of the College of Health and Human Services in October 2017, Dr. Buck Louis was the Director for the Division of Intramural Population Health Research at the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), National Institutes of Health.  This position was preceded by her role as a tenured professor in the Department of Social and Preventive Medicine, University of Buffalo, School of Medicine and Biomedical Sciences, where she taught in both the graduate and medical schools.  She has published numerous scientific papers and technical reports, and co-edited the textbook Reproductive and Perinatal Epidemiology.  She has provided considerable service to The National Academies, Pan American Health Organization, U.S. Environmental Protection Agency, and World Health Organization among other governmental agencies.  She has been the President of the Society for Pediatric and Perinatal Epidemiologic Research, President of the Society for Epidemiologic Research and Councilor for the International Society for Environmental Epidemiology.  Currently, Dr. Buck Louis serves on the Board for the American College of Epidemiology and the Board on Environmental Studies and Toxicology (BEST), National Academies of Sciences, Engineering and Medicine.  Dr. Buck Louis is the recipient of many awards for research excellence, mentoring and service.
