Ruijie Liu

Ruijie Liu is a fifth-year PhD candidate in Health Policy and Management at the Yale School of Public Health.

Her research focuses on the intersection of health policy, service delivery, and health outcomes, with particular attention to mental health and substance use treatment. These include studies of Medicare and Medicaid reforms, mental health parity laws, public insurance consolidation, hospital payment models based on diagnosis-related groups, and health-related quality of life.

Her dissertation project uses causal inference methods and claims data to examine how alternative payment models, alongside service provision requirements, shape the delivery of evidence-based behavioral health treatment and influence physical and mental health outcomes in the context of Medicaid.
