Personal Statement

My research examines the provision and financing of health care in low-income populations.  One stream of my work examines the implementation of alternative payment models (including value-based purchasing and global budgets), their impacts on care quality and utilization, and their financial implications for providers serving socially disadvantaged patients.  A second stream of work examines interactions between health insurance (principally Medicaid) and other public assistance programs, including housing and nutrition assistance.  This work aims to identify potential complementarities between Medicaid and safety-net programs that may improve Medicaid's operating efficiency and benefits to enrollees.  My work uses simulation and econometric methods for causal inference to inform policymakers about the public health and financial impacts of such payment and delivery system innovations.  My work has appeared in Health Affairs, JAMA Internal Medicine, Annals of Internal Medicine, Health Services Research, and other leading health policy journals.  I am the receipient of a career development (K01) award from the Agency for Healthcare Research and Quality to examine the effects of Medicaid eligibility and payment policies on dual Medicare-Medicaid beneficiaries' access to care and health outcomes.
