Liping Feng
Associate Professor of Obstetrics and Gynecology

Liping Feng, MD's research has focused on understanding the mechanisms of pregnancy complications associated with placental development. These works are translated then to the clinical care of women through studies dedicated to identify risk factors and novel biomarkers for early prediction and prevention of adverse birth outcomes.

Dr. Feng devotes her entire career to improving pregnancy outcomes through innovative research. Dr. Feng conducts both basic science/laboratory research, as well as participates in clinical studies. Her laboratory has focused on understanding the mechanisms of placenta-originated pregnancy complications such as preeclampsia and still birth, which are important causes of perinatal and neonates’ mortality and morbidity. Currently, she has three lines of investigation focused on the roles of inflammation/infection, cell aging, and environmental exposure in placental development and subsequent pregnancy complications.

In addition, Dr. Feng has established an international collaboration in Global Women’s Health. She has affiliated with the Duke Global Health Institute (DGHI) and participates in a DGHI research. She has an interest in DGHI education, and service or policy initiatives, including mentoring and teaching graduate and professional students on fieldwork and research.

Current Research Interests

Maternal Environmental Exposure of Endocrine Disrupting Chemicals and Pregnancy Outcomes.

Ureaplasma Parvum Infection and Preterm Premature Rupture of Fetal Membranes.
