My interests are in the theory and application of psychometric methods in education and psychology. I am especially interested in the application of latent variable models for purposes of test validation, assessment of individual differences (such as response styles), and cognitive diagnosis.
Most of my research is in item response theory (IRT), including its application to issues such as differential item functioning and test dimensionality assessment. I am also interested in the development of nonparametric IRT methods, which relax certain modeling assumptions and have the potential to increase the flexibility and efficiency of IRT in many testing applications.
