Research Interests
Dr. Ryan’s work centers on the empirical evaluation of health-policy interventions, with particular emphasis on how alternative payment models—pay-for-performance, bundled payments, and Medicare Advantage reforms—affect quality, spending, and equity of care. He employs quasi-experimental designs and large administrative datasets to assess causal impacts of policy on provider behavior and patient outcomes.
His investigations span Medicare hospital value-based purchasing, the Medicare Shared Savings Program, Medicare Advantage star ratings and overpayments, state-level affordability standards, and the distributional consequences of payment reform on disadvantaged populations.
Publication Trends
Across more than 100 peer-reviewed articles, Ryan’s recent output (2023-2025) exhibits three dominant themes: (1) rigorous assessment of Medicare Advantage payment accuracy and market behavior, including favorable selection and vertical integration; (2) evaluation of bundled-payment and ACO models on surgical quality and spending; and (3) methodological advances in difference-in-differences and propensity-score techniques applied to claims data. These studies appear in top-tier journals such as New England Journal of Medicine, JAMA, The Lancet, and Health Affairs.
