Tiffany A. Moore Simas, MD, MPH, MEd, FACOG, is Associate Professor of Obstetrics & Gynecology and Pediatrics at the University of Massachusetts Medical School, and Director of the Obstetrics & Gynecology Research Division. Her core ideology is to advance the reproductive health and well-being of women, as well as their children, families and community, through evidence-based investigation. Her specific research interests and efforts are focused broadly on the pregnancy time period. Pregnancy is a very unique state of altered physiology that can act as a stress test and thus a crystal ball through which increased risks for both immediate and long-term maternal and fetal cardiometabolic conditions are uncovered and/or can be predicted. Additionally, pregnancy is often a time when women are highly motivated to engage in beneficial behavioral changes. Despite pregnancy being associated with near universal weight gain, placental production of a myriad of hormones and other soluble systemically influencing substances, only a fraction of women experience obstetric complications like preeclampsia and gestational diabetes. These pregnancy-specific diseases are associated with higher risk of lifetime cardiovascular disease, diabetes, and weight gain. Dr. Moore Simas seeks to uncover behavioral, demographic, pathophysiologic and other differences with regards to which maternal-fetal dyads will develop these conditions as compared to those that do not. An understanding of these differences will inform collaborative interventional work and potential disease mechanisms linked to their more chronic disease counterparts.
