Biography

I am an Associate Professor in the T. Denny Sanford School of Social & Family Dynamics, specializing in Measurement and Statistical Analysis. My research and teaching interests include methodological investigations and applications in psychometrics and statistical modeling, focusing on item response theory, structural equation modeling, and Bayesian approaches to inference and modeling. I also work in areas of assessment design, focusing on evidentiary principles and applications in simulation-based assessments.

  • B.A. Philosophy, University of Maryland 2001
Research Interests

Dr. Levy's work primarily concerns the use of statistical and psychometric models in assessment, education, and the social sciences more broadly. His interests include methodological investigations and applications in psychometrics and statistical modeling, with a focus on models and procedures associated with item response theory, structural equation modeling, Bayesian networks, and Bayesian approaches to inference. In connection with these areas, his current interests include dimensionality assessment, model checking, and model comparison. Dr. Levy also works in the area of assessment design, focusing on evidentiary principles and applications in complex, simulation-based assessments.
