I conduct health policy research with the belief that rigorous evaluation can inform public policy decisions and ultimately lead to better, and more equitable, population health. My current research examines how health insurance coverage policy affects health care utilization, costs, health outcomes, and health disparities. To do so, I employ observational and quasi-experimental methods to derive policy insights from large datasets, including population surveys, vital statistics, and administrative claims.
Insurance Coverage and Access to Care for Reproductive-Age and Pregnant Women
Insurance coverage is critical for ensuring that women have access to preventive care, including but not limited to the period surrounding pregnancy. This body of work focuses on characterizing the patterns of health insurance coverage for reproductive-age women in the U.S. and evaluating the impacts of the Affordable Care Act on women and children.

Prescription Drug Coverage and Pricing Policy
Prescription drugs represent a large and growing proportion of health care costs in the U.S. and other developed countries. My research on pharmaceutical policy focuses on (1) evaluating the impact of prescription drug coverage and pricing policies on access and costs, and (2) studying how prescription drug coverage policies develop, especially in relation to existing social programs.
Much of this work focuses on Canada, a country with a prescription drug coverage policy that is unique in the world: Canada is the only country with a universal health insurance scheme that excludes prescription medicines.

Improving Methods for Health Policy Evaluation
Knowing what policies and programs work to improve health - and which don't - is critical for allocating scarce resources. This body of work aims to reduce uncertainty around common challenges in health policy evaluation and contribute to the development of 'gold standard' observational methods.
