Dr. Ryan Longman, a leading obstetrician and gynecologist who specializes in medical genetics and obstetric and gynecologic ultrasound, has been named chief of the Department of Obstetrics and Gynecology at NewYork-Presbyterian Lower Manhattan Hospital and recruited as an associate professor of clinical obstetrics and gynecology at Weill Cornell Medicine, effective Jan. 12.

“I’m thrilled to join the incredible team of women’s health experts at NewYork-Presbyterian and Weill Cornell Medicine, who share my commitment to delivering personalized, exceptional care to women,” said Dr. Longman. “I look forward to leading through collaboration and team building to grow the women’s health program at NewYork-Presbyterian Lower Manhattan Hospital and reach more patients in need of our high-quality care.”

Dr. Longman will lead a world-class, multidisciplinary team of women’s health specialists who provide comprehensive health care services, spanning prenatal and postpartum services, gynecologic cancer screenings, treatment of reproductive disorders, family planning, and preventative care. He will also oversee a new, expanded maternity center at NewYork-Presbyterian Lower Manhattan Hospital, coming this year, that will feature 24 private postpartum rooms, fully renovated labor and delivery suites, and the latest technology and resources to support families.

“We are delighted to welcome Dr. Longman to NewYork-Presbyterian Lower Manhattan Hospital and look forward to his leadership enhancing women’s health services for the Lower Manhattan community,” said Dr. Paresh Shah, group senior vice president and chief operating officer, NewYork-Presbyterian/Weill Cornell Division, who oversees operations at NewYork-Presbyterian Lower Manhattan Hospital.

“Dr. Longman is a skilled physician, accomplished geneticist and leader who is dedicated to providing the highest quality, most compassionate care to women and families in Lower Manhattan and beyond,” said Dr. Laura Riley, obstetrician and gynecologist-in-chief at NewYork-Presbyterian/Weill Cornell Medical Center and chair of the Department of Obstetrics and Gynecology at Weill Cornell Medicine.

Dr. Longman provides routine and condition-specific care for both pregnant and nonpregnant patients. He has a particular interest in using ultrasound technology to advance and refine imaging for more accurate and earlier diagnosis and treatment of gynecological conditions. His practice specializes in imaging for endometriosis, a condition in which cells similar to the lining of the uterus grow outside the uterus, causing pelvic pain and other symptoms, as well as fetal anatomy imaging to diagnose fetal anomalies before 14 weeks of pregnancy.

Dr. Longman joins NewYork-Presbyterian from the University of Chicago Medicine, where he served as the section chief of Ultrasound, Genetics, and the Fetal Neonatal Care Center. His scientific career, spanning 20 years, includes research on the genetics of rheumatic disease and epilepsy, carrier screening in prenatal diagnosis, ultrasound imaging for detecting fibroids, and the development of AI models for diagnosis of adnexal masses, such as ovarian cysts. He was co-editor for the textbook, First-Trimester Ultrasound: A Comprehensive Guide, 2nd Edition, a reference found in high-risk obstetric ultrasound units across the country. He also helped to create a cell phone interface program used with portable ultrasound probes for fetal assessment in remote areas. He has served as a volunteer physician for the Victor Center, improving access to carrier screening of inherited genetic disorders, and was the Maimonides Society Committee Chair for Greater Miami Jewish Federation, supporting social services for individuals in need.

Dr. Longman earned his bachelor’s degree at the University of Pennsylvania. After a two-year research fellowship at the National Institutes of Health, he pursued his medical degree at Thomas Jefferson University. He completed a residency in obstetrics and gynecology at the Mount Sinai School of Medicine in New York, a fellowship in maternal-fetal medicine, and a second residency in medical genetics at the University of Michigan Medical School.
