Professor Jae Woo Choi's research lab focuses on health economics, health policy, and the socioeconomic determinants of health outcomes in aging populations. The lab investigates catastrophic health expenditures, poverty-related health risks, and the impact of chronic diseases—particularly cancer and dementia—on household economic status and mortality. Using large-scale national health databases, the lab examines the interplay between healthcare financing, disease burden, and population health, with a strong emphasis on policy-relevant outcomes in South Korea.
