Courtney Lyles, PhD

Associate Professor

Courtney Lyles, PhD, is an Associate Professor in the UCSF Division of General Internal Medicine at Zuckerberg San Francisco General Hospital, the UCSF Center for Vulnerable Populations, and the UCSF Department of Epidemiology and Biostatistics. She also serves as co-Director of the Innovation in Research and Informatics core for the UCSF CTSI, and co-directs the UCSF Population Health Data Initiative. A trained health services researcher, she uses quantitative and qualitative methods to examine quality of care, health behavior, and health outcomes.

Her research specifically focuses on harnessing health information technology to improve chronic disease management to ultimately reduce disparities in health and healthcare outcomes. Her research portfolio spans digital health design and testing, evaluation, and implementation, including several large digital health studies for improving diabetes, depression, hypertension, and referrals to community-based health and social resources.
