Biography/Research
Dr. Levy’s 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. He also works in areas of assessment design, focusing on evidentiary principles and applications in simulation-based assessments. Dr. Levy received his B.A. in Philosophy from the University of Maryland in 2001, M.A. in Measurement, Statistics & Evaluation from the University of Maryland in 2002, and his Ph.D. in Measurement, Statistics & Evaluation from the University of Maryland in 2006. He was awarded a Harold Gulliksen Psychometric Research Fellowship by Educational Testing Service for 2005-2006 to support his doctoral dissertation research. In 2008 he was presented with the Brenda H. Loyd Outstanding Dissertation Award by the National Council on Measurement in Education for this work. Dr. Levy was named a 2010 recipient of the Presidential Early Career Award for Scientists and Engineers.
