Margeaux W Marbrey

Assistant Professor in Obstetrics and Gynecology
Obstetrics and Gynecology, Reproductive Sciences

Overview


Dr. Margeaux W. Marbrey received her PhD from Baylor College of Medicine while studying how progesterone signaling regulates implantation in a spatiotemporal manner under the mentorship of Dr. Francesco DeMayo. Dr. Marbrey then completed a postdoctoral fellowship at the University of North Carolina Chapel Hill School of Medicine with Dr. Kathleen Caron discerning effects of toxicants, environmental exposures, and tobacco products on pregnancy health, timing, and disease.

The chief aim of the Marbrey Laboratory is to understand molecular regulators of early and mid pregnancy success using exposure paradigms and cutting-edge models to further understand human reproduction, promote healthy pregnancies, and improve patient care. The Marbrey laboratory builds upon Dr. Marbrey's strong experience using innovative models and exposure systems to answer important questions in pregnancy that ultimately lead to public health awareness, risk assessment, and preserved lives of mother and baby.
