Biosketch

I am a Professor at Arizona State University, appointed in the Quantitative Psychology area in the Department of Psychology, as well as in the T. Denny Sanford School of Social & Family Dynamics specializing in Quantitative Methodology. My research and teaching interests include methodological investigations and applications in psychometrics and statistical modeling, focusing on item response theory, structural equation modeling, Bayesian networks, 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. Here you can find information on my courses, papers and software, and information on my book with Bob Mislevy, Bayesian Psychometric Modeling.
