Dr. Xu Ji is a Prevention Effectiveness Fellow at the Centers for Disease Control and Prevention (CDC). Dr. Ji’s research centers on the intersection of policy evaluation, health and behavioral health services research among vulnerable populations, and big data analytics, with a particular focus on those with public health insurance. Her doctoral dissertation used national Medicaid Analytic eXtract Files and data from the Medical Expenditure Panel Survey to understand how Medicaid eligibility policies and discontinuous insurance coverage affect mental health care utilization and outcomes among children and adults. Her findings shed light on the importance of continuous Medicaid coverage for low-income individuals with mental health disorders, as well as potential health policy levers that can be used to reduce Medicaid disenrollment. 

Her research has been published in Medical Care, JAMA Psychiatry, Psychiatric Services, and Pediatrics, and has been featured in U.S. News, NBC.com, and Reuters Health.  Dr. Ji holds an M.S.P.H from Emory University Rollins School of Public Health.  She then received her Ph.D. in Health Services Research and Health Policy with a concentration in economics at Emory University.
