Academic Interests

Measuring and trying to explain why people differ on basic human skills and abilities remains an intriguing topic. As a Psychometrician I am interested in all aspects of Assessment, Evaluation, and Testing, with a specific passion for the Development and Application of Latent Variable Models in a new measurement context.

The figure above represents the classical typology of latent variable models. Current advances are combining and extending these types across their default boundaries, and adding structural elements on top of the measurement models (i.e., generalized structural equation modeling: SEM).

General Interest: Measuring individual differences
General Background: Psychology, Statistics, & Educational Testing
Research Domain: Psychometrics and Latent Variable Models
Research Niche 1: Local item dependence and Integration of Copula Functions in Latent Variable Models
Research Niche 2: Explanatory IRT and modern test design (Item models, AIG, CAT)
