Wendy Xu

Wendy Xu's research focuses on health policy and health economics, particularly Medicare Advantage, dementia care, and billing regulations in the U.S. healthcare system. Her work examines how insurance design, rural-urban location, and regulatory policies (like surprise billing laws) affect access to care, treatment patterns, and health outcomes for populations such as older adults, people with dementia, and patients with chronic or substance use conditions. This work draws on large administrative and claims datasets to evaluate disparities and the effects of healthcare policy changes.
