Su Lab

Research interests:
Since completion of her Obstetrics and Gynecology residency and her Maternal-Fetal Medicine fellowship at Northwestern University in Chicago, Dr. Su has been continuously grant-funded through various societies and the National Institutes of Health.  She joined the faculty of the University of Colorado in 2015, where she continues a balance of clinical work and research.  her primary research interest has been focused upon molecular mechanisms underlying placental insufficiency and abnormal fetoplacental blood flow in fetal growth restriction.  She was awarded the 2015 President's Achievement Award from the Society for Reproductive Investigation.
