About Me

Since childhood, I wanted to be a doctor. I was an avid reader of young adult novels that addressed the effect that medical conditions can have on a person and their relationships with family and friends. I became passionate about women’s health following my undergraduate years at Barnard College, a women’s college. Ultimately, this prompted me to specialize in obstetrics and gynecology.

I offer prenatal care and consultations for patients and couples with high-risk pregnancies. I also see a large number of women with low-risk pregnancies for routine prenatal ultrasounds, often referred by their primary obstetrician and gynecologist. I perform prenatal genetic diagnostic testing, including chorionic villus sampling and amniocentesis, in the office. Additionally, I perform inpatient procedures, such as external cephalic version, cerclage placement, and deliveries.

I work alongside a team that is highly specialized in high-risk pregnancies. NYU Winthrop Hospital, part of NYU Langone, has the only fetal surgery program on Long Island, offering in utero procedures for fetuses at risk. I am committed to reducing anxiety by offering expert and compassionate care to all my patients.

I am one of NYU Winthrop Hospital’s site principal investigators for the Perinatal Research Consortium, which comprises ten medical centers devoted to perinatal research. My research focuses on evaluating the effect of in utero exposure to flame retardant chemicals on neurodevelopmental outcomes in offspring. I am also actively involved in clinical research studies.

I am proud to be a member of the Society for Maternal–Fetal Medicine and American College of Obstetricians and Gynecologists.
