Research Interests:

  • Psychological measurement theory
  • Statistical and mathematical methodology
  • Longitudinal and lifespan modeling


As the primary methodologist in the psychology department, I work closely with the developmental faculty and students.

Currently, I am constructing mathematical/statistical models for psychological attributes which are measured longitudinally. In particular, I am interested in the development of human cognitive skills/abilities and intelligence throughout the life-span. Especially important in this endeavor are (1) the study of change; (2) the effects of interventions; (3) the stability of abilities; and (4) the correlates of change.

Additionally, I have research interests in multivariate statistical techniques, measurement, test theory, and research methodology.
