I am at the Department of Psychology & Neuroscience, and the L.L. Thurstone Psychometric Laboratory, at the University of North Carolina at Chapel Hill. I am retired from teaching in the graduate program in quantitative psychology, and in the undergraduate program in psychology—mostly on topics in the areas of psychological testing and measurement and item response theory.

In collaboration with graduate students here and colleagues elsewhere, I am involved in research on contemporary developments in the theory of educational and psychological testing.
