About Mark Clapp, MD, MPH

Dr. Clapp is a maternal-fetal medicine provider in the Department of Obstetrics and Gynecology. He completed his medical degree at the University of North Carolina and Masters in Public Health at Harvard School of Public Health. He completed residency in obstetrics and gynecology, including serving as Chief Resident, at Massachusetts General Hospital and Brigham and Women's Hospital and fellowship in maternal-fetal medicine at Massachusetts General Hospital. His clinical activities include performing ultrasound and ultrasound-guided procedures (including chorionic villus sampling and amniocentesis), seeing patients in his high-risk pregnancy clinic, and serving as the attending physician on the Labor and Delivery unit and the Antepartum unit. His clinic welcomes patients with a wide range of high-risk conditions in pregnancy, including both maternal conditions (such as high blood pressure, autoimmune diseases, or cardiac conditions) or fetal conditions (such as multiple gestations or pregnancies with genetic disorders or unexpected ultrasound findings). He strives to deliver evidence-based, compassionate, timely care to all patients.

When he is not seeing patients, he serves as the Medical Director for Perinatal Analytics and is an active member within the Deborah Kelly Center for Clinical Research within the department. His research interests include studying quality and patient safety of obstetrical care and examining the effects of health policies on obstetrical outcomes and women's access to pregnancy-related care. He currently is exploring opportunities for risk stratification and prediction for adverse maternal and neonatal outcomes during labor and delivery. His work has been funded by the American College of Obstetricians and Gynecologists, the Society for Maternal-Fetal Medicine, the American Association for Obstetricians and Gynecologists Foundation, the Harvard Risk Management Foundation, and the National Institute for Health Care Management.
