Maria DeYoreo is a statistician at the RAND Corporation. Her methodological interests include Bayesian modeling, Bayesian nonparametrics, missing data imputation and data fusion, and causal inference. DeYoreo's substantive interests include health care quality and provider performance assessment, military health, mental health and substance abuse treatment, and colorectal cancer. She co-leads a team that works with the Center for Medicare & Medicaid Services to generate the Medicare Advantage Star Ratings. Her research experience also includes the following topic areas: microsimulation models for colorectal cancer, sexual assault and suicide in the military, health systems, trends in substance abuse and mental health treatment. DeYoreo received her B.S. in mathematical sciences from the University of California, Santa Barbara, and her Ph.D. in statistics from the University of California, Santa Cruz, where she developed flexible Bayesian nonparametric models for ordinal regression. She completed postdoctoral research at Duke University, where she developed imputation models for mixed multivariate outcomes, and modeling approaches for data fusion and measurement error.
