Profile Headshot



Dr. Gyamfi is board certified in both Obstetrics/Gynecology and Maternal-Fetal Medicine. As a Maternal-Fetal Medicine (MFM) specialist, she focuses on obstetric complications with a primary focus on preterm birth prevention. However, she also focuses on gestational diabetes, preeclampsia and thrombophilias in pregnancy. Her clinical practice includes caring for high risk patients, performing detailed ultrasounds and procedures for prenatal diagnosis. She is the Director of the Maternal-Fetal Medicine Fellowship Training Program, where she oversees the training and development of future MFM physicians.

Dr. Gyamfi is also a proficient, NIH-funded researcher working on multiple clinical trials. As lead PI, she recently completed the multi-center, randomized ALPS trial designed to improve neonatal outcomes in infants of women at risk for late preterm birth. This paper is now published in the New England Journal of Medicine. A long-term follow-up to this study is underway. She also conducts research in the areas of preterm birth, antenatal corticosteroids, preeclampsia, CMV, and genetic determinants of neonatal respiratory morbidity related to preterm birth. Her Masters of Science degree in Biostatistics allows her the opportunity to run analyses on existing or developed datasets and provides a unique insight into clinical obstetric research. She is the PI of the Maternal-Fetal Medicine Units Network at the National Institutes of Health and has numerous publications in the area of prematurity, antenatal corticosteroids, thyroid disease, and Jehovah’s Witness care.

Aside from her clinical and research endeavors, Dr. Gyamfi served as a member of the Board of the Society for Maternal-Fetal Medicine (SMFM). She served as a member of the SMFM Publications Committee, a national group of highly-regarded MFM specialists who write guidelines on clinical practice for MFM-subspecialists; and was a founding member of the SMFM Research Committee. She has been selected as a faculty member for the annual NICHD conference directed at stimulating research interests and collaboration between MFM and Neonatal fellows-in-training on various occasions, and she has served as the Chair of the AAP/Abbott sponsored Santa Fe conference for Neonatal and Perinatal Fellows. As MFM Fellowship Director at Columbia University, she oversees the training of 9 fellows, making this one of the largest training programs in the country. She has been invited to speak about her research locally, nationally, and internationally; and she is a member of AGOS.

Dr. Gyamfi’s special interests include epidemiology and biostatistics as well as maternal and obstetric complications of pregnancy including prevention of preterm birth, diabetes in pregnancy, antenatal corticosteroids, chronic hypertension, thrombophilias, and anemia.
