One area of my research consists of developing novel Bayesian parametric and nonparametric item response theory (IRT) models to more effectively examine the quality of educational and psychological test data. Another aspect of my research focuses on evaluating and refining rating instruments that measure the quality of daycare centers and mental health-related constructs.
