Dr. Liu's research centers on health policy and its financial implications within the U.S. healthcare system. Her work explores Medicare and Medicare Advantage, insurance design, drug access and affordability, pricing and payment models, and healthcare expenditure. She uses a systems-level, supply-side approach to evaluate how policy changes affect patient outcomes, provider behavior, and cost efficiency.

Her recent publications (2023–2025) reveal a strong focus on pharmaceutical policy (e.g., biosimilars, step therapy), geographic variation in spending, and avoidable hospitalizations. These works span journals like JAMA Health Forum and the Journal of Managed Care & Specialty Pharmacy, indicating a high-impact, policy-relevant research trajectory.
