OB/GYN


The Obstetrics and Gynecology Specialty Research Group is a collaboration of research-oriented physicians who seek evidence-based strategies to improve clinical care.

Some topics of interest include, ambulatory gyn care, cancer prevention/screening, intrapartum care, prenatal care, disparities in care/mental health, delivery of care, and surgical outcomes.
