Biography
Dr. Reddy graduated from Brown University Magna cum laude and received her M.D. degree from the Warren Alpert Medical School of Brown University. Dr. Reddy also earned a Masters in Public Health (M.P.H.) from the Johns Hopkins Bloomberg School of Public Health. She completed her residency in Obstetrics and Gynecology at the Johns Hopkins Hospital and remained there as a Robert Wood Johnson Clinical Scholar. She completed her Maternal-Fetal Medicine fellowship at Thomas Jefferson University. She was a faculty member at the University of Maryland School of Medicine prior to joining the National Institutes of Health (NIH) as a Medical Officer in the Pregnancy and Perinatology Branch of the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD). During her tenure at NIH, she provided MFM clinical services at Walter Reed Medical Center (Bethesda, MD) and then Medstar Washington Hospital Center (Washington, DC) as a Professor of Obstetrics and Gynecology at the Georgetown University School of Medicine prior to joining Yale in 2018.
While at NIH, she oversaw many of the largest and most influential studies in obstetrics, including directing the Maternal-Fetal Medicine Units (MFMU) Network which funds multiple clinical trials across the country. Her research on stillbirth as part of the Stillbirth Collaborative Research Network (SCRN), preterm birth and labor management has had a profound impact on obstetrical practice both in the United States and internationally. She received numerous NIH awards for her role in advancing women’s health research agenda nationally.
Dr. Reddy is widely recognized as a scholar, educator, and mentor. Dr. Reddy has been selected to serve as a Member of the American College of Obstetrics and Gynecology (ACOG) Committee on Practice Bulletins – Obstetrics; Fellow of the American Gynecological & Obstetrical Society and was selected as Fellow in Executive Leadership in Academic Medicine (ELAM) Program for Women, 2020-2021 Class. She has published 250 peer reviewed articles, many in the most impactful journals including NEJM and JAMA.
Dr. Reddy is board certified in Obstetrics and Gynecology and Maternal-Fetal Medicine. Her expertise is in the management of high-risk pregnancies complicated by prior preterm birth or pregnancy loss as well as maternal conditions such as diabetes, hypertension, and connective tissue disorders such as lupus.
