More Experts


Beth Ann Griffin is a senior statistician at the RAND Corporation, where she codirects the RAND Center for Causal Inference. Her statistical research focuses on causal effects estimation when using observational data and innovative techniques for the analysis of time-to-event data. Her substantive research has primarily fallen into three areas: (1) substance abuse treatment for adolescents, (2) neighborhood level predictors of health, and (3) military health. Examples of recent studies include case-mix adjustment for evaluating substance abuse treatment programs, quasi-experimental evaluation of a summer camp program for military youth, and a five-year study evaluating the impact of Carnegie Learning's new technology-based algebra I curriculum. Griffin's research has appeared in leading journals such as Drug and Alcohol Dependence, Journal of Substance Abuse Treatment, Statistics in Medicine, Journal of the American Statistical Association, Annals of Applied Statistics, American Journal of Public Health, Health and Place, Environmental Health Perspectives, and Educational Evaluation and Policy Analysis. She is currently the principal investigator of a project sponsored by the National Institute of Drug Abuse (NIDA) to improve a promising health services research tool (the TWANG package) for estimating causal effects of treatment using propensity score weights. Griffin also serves on the editorial board the Annals of Applied Statistics. She received her Ph.D. in biostatistics from Harvard University.

Recent Projects

  • Estimating the cumulative effects of treatment for adolescents with substance use disorders
  • Using case-mix adjustment to identify quality indicators for treatment facilities serving adolescents with substance use disorders
  • Examining the association between health outcomes and neighborhood characteristics such as neighborhood socioeconomic status, urban sprawl, and ambient air particulate matter
