I am a health economist specializing in health behaviors, health policy evaluation, and economic evaluation. My research addresses a range of empirical policy-relevant topics in health behaviors and health outcomes (e.g. smoking, drinking, physical activity, obesity), healthcare financing, health services research, and cost-effectiveness analysis. My research applies various micro-econometric techniques (particularly, quasi-experimental methods) and economic theory to individual-level data from social surveys and administrative databases.
