My research focuses on the health of vulnerable populations (e.g., mothers and children, the homeless, the food insecure, and Medicaid enrollees) across the lifespan. My research largely involves longitudinal data and econometric techniques in order to provide persuasive evidence about causal mechanisms. My methodological expertise includes applied econometrics, longitudinal data analysis, time use data analysis, health care claims data analysis, survey research, survey validation methodology, ecological momentary assessment (EMA) data analysis, and economic evaluation/cost analysis. My research can be described by three main lines of inquiry: 1) The effect of poor health on economic status, 2) Health and housing, and 3) Policies/programs related to unhealthy behaviors.
