Research

Ask what changed—then test why.

My research examines how policy, financing, systems, and implementation choices affect outcomes, stability, access, and equity.

Research agenda

Doctoral research

Evaluating U.S. Health Policy Levers on Outcomes and Stability Using Difference-in-Differences: Consolidation, Global Budgets, and Income Policies.

This three-study portfolio examines how policy interventions affect hospital performance and population health. The work uses quasi-experimental designs, administrative and survey data, robustness checks, and transparent attention to identifying assumptions.

Study 01

Hospital acquisitions

Examining changes associated with ownership transitions and consolidation.

Study 02

Maryland global budgets

Comparing hospital margins and revenue per discharge under an all-payer global budget model.

Study 03

Income policy & health

Assessing whether income-policy differences translate into changes in self-rated health.

Across the portfolio

Credible interpretation

Testing assumptions, examining trends, documenting limitations, and separating association from defensible causal claims.

Methods and analytic approach

Causal inference

Quasi-experimental design

Difference-in-differences, staggered adoption, event-study logic, comparison-group design, and sensitivity analysis.

Health services

Administrative & survey data

Hospital financial and operational data, provider characteristics, population-health surveys, and policy datasets.

Evaluation

Mixed-methods evidence

Quantitative measurement strengthened by qualitative inquiry, document analysis, stakeholder perspectives, and implementation context.

Translation

Decision-ready outputs

Methods and results communicated through clear limitations, actionable findings, monitoring measures, and implementation implications.

Research principles

A result is only as useful as the question it answers, the assumptions it survives, and the decisions it can responsibly support.

My research practice emphasizes reproducible logic, appropriate comparison, explicit limitations, ethical data use, and communication that avoids overstating what the evidence can establish.
