Zhang Zhang studies how technology innovation, health policy, and care delivery can improve outcomes for people with complex health conditions and promote healthy aging. Her work focuses on digital health, health information systems, artificial intelligence, value-based payment, preventive and integrated care, and aging.

Zhang uses causal inference, quantitative modeling and applied economics approaches to evaluate policy, service innovation and clinical interventions. Her expertise includes randomized trials, quasi-experimental designs and the use of health services research methods to understand how innovations and policies affect care delivery, outcomes and equity.   

Before joining Washington University, Zhang was a postdoctoral fellow appointed jointly in the Health Services and Outcomes Research in Aging Populations T32 program and the Hopkins Business of Health Initiative at Johns Hopkins Bloomberg School of Public Health. She earned her PhD in health economics from the University of North Carolina at Chapel Hill, where she was a predoctoral trainee at the Carolina Population Center, and earned her MSc in health policy, planning and financing from the London School of Economics and the London School of Hygiene and Tropical Medicine. Her research has been funded by the National Bureau of Economic Research, the National Heart, Lung, and Blood Institute, and the National Institute on Aging.
