I received my PhD in global health management and policy from the Tulane University School of Public Health and Tropical Medicine, my MPH in health management and policy from the Drexel Dornsife School of Public Health, and my BA from Reed College.

Research, Education and Clinical Interests

My research focuses on a wide range of health services research topics, but it is particularly attentive to the issues of organizational change for primary care and health systems. In this context, my work examines and facilitates collaborative relationships across healthcare sectors to support population health and advance health equity. I approach these topics using theories that draw from organizational science, dissemination and implementation science, and health behavior. Using both quantitative and qualitative methods, I aim to produce practice oriented conclusions that can benefit healthcare delivery and cross-sector partnerships between healthcare and community-based organizations.
