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 Department of Epidemiology and Biostatistics. A trained health services researcher, she uses quantitative and qualitative methods to examine quality of care, health behavior, and health outcomes. She is also an Associate Director of the UCSF program Implementation Science program based in the Department of Epidemiology and Biostatistics. Finally, she holds an affiliate investigator appointment at the Kaiser Permanente Northern California Division of Research.

Her research specifically focuses on harnessing health information technology to improve patient-provider communication for chronic disease self-management to ultimately reduce disparities in health and healthcare outcomes for low-income and racial/ethnic minority populations. She currently is co-PI of an R01 from the Agency for Healthcare Research and Quality to use machine learning to send personalized text messages to patients motivate physical activity, including leveraging user-centered design and implementation science principles.
