Where I Work: The University of Kansas
I have a split position with one part as a tenured associate professor in the Department of Educational Psychology and one part as an associate research scientist in the Achievement and Assessment Institute.
My research interests are focused on the development of psychometric and general quantitative methods, as applied in the psychological, educational, and social sciences. I teach courses on advanced quantitative methodology with an emphasis on statistical/psychometric modeling, model estimation, and the integration and generalities of popular statistical and psychometric techniques.
Diagnostic Classification Models
The main focus of my research has been on the development of diagnostic classification models (DCMs). DCMs are psychometric models with categorical latent variables that are used to provide multidimensional feedback from tests and surveys. I am a coauthor of the book Diagnostic Measurement: Theory Methods and Practice, describes the theory behind DCMs and how to implement DCMs in research and large scale testing programs.
