Dr. Ahmet Baschat is director of the Center for Fetal Therapy and professor in the Johns Hopkins Medicine Department of Gynecology and Obstetrics. His areas of clinical expertise include prenatal treatment of intrauterine growth restriction and fetal interventions for twin-to-twin transfusion syndrome (TTTS), as well as other complications of monochorionic twin pregnancies.

Dr. Baschat received his undergraduate and medical degrees from The Royal College of Surgeons in Ireland. He earned his doctorate in medicine (Dr. Med) from the University of Lübeck, where he also completed a residency in obstetrics and gynecology. Dr. Baschat also completed residencies at Newton-Wellesley Hospital and at University of Maryland Medical Center.  He performed a fellowship in maternal-fetal medicine at University of Maryland Medical Center and went on to develop their Center for Advanced Fetal Care. Dr. Baschat joined the Johns Hopkins faculty in 2014.

Prior to joining Johns Hopkins, Dr. Baschat was professor and director of Maternal-Fetal Medicine at the University of Maryland School of Medicine.

Dr. Baschat’s research interests include interventions and management techniques for fetal growth restriction and placental insufficiency. He has also done extensive research on the use of high resolution prenatal ultrasound techniques, including Doppler and fetal echocardiography, to predict and detect fetal complications.

Dr. Baschat serves on a variety of boards and is a member of the American College of Obstetrics & Gynecology (ACOG), the International Society of Ultrasound in Obstetrics & Gynecology and the International Fetal Medicine and Surgery Society. He has been recognized with several awards and honors, including the 2010 Award for Excellence in Research by the Society for Maternal-Fetal Medicine.
