General Internal Medicine


I am an Assistant Professor of Medicine at Boston University School of Medicine and a primary care physician in the Women's Health Unit at Boston Medical Center (BMC).

My research focuses on the integration of sexual and reproductive health care into primary care. I am particularly interested in improving primary care after pregnancy complications associated with future chronic diseases (e.g. preeclampsia associated with chronic hypertension and cardiovascular disease, CVD). Previously I have used administrative data to characterize postpartum health risks and acute care use after hypertensive pregnancies. My current work focuses on: (1) defining the role of the primary care clinicians in postpartum care, (2) understanding patterns of pregnancy-related CVD risk and follow-up at BMC, and (3) identifying multilevel barriers to postpartum follow-up at BMC. In the future, I hope to develop interventions that improve postpartum care coordination and primary care follow-up for BMC patients with elevated chronic disease risks.

Areas of Interest:
Primary care; Chronic disease prevention and management; Pregnancy-related CVD risk; Family planning; Care coordination; Health services research
