Courtney Lyles, PhD, is an affiliate Professor in the UCSF Division of General Internal Medicine at Zuckerberg San Francisco General Hospital and the UCSF Center for Vulnerable Populations. She is also a Professor and Director of the Center for Healthcare Research and Policy at the UC Davis School of Medicine. A trained health services researcher, she uses quantitative and qualitative methods to examine digital health, quality of care, health behavior, and health outcomes.

Her research specifically focuses on harnessing health information technology to ultimately reduce inequities 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. Finally, she uses large-scale datasets to conduct detailed analyses of the impact of health and healthcare programs on longitudinal outcomes.
