I study quantitative methodology for psychological research, primarily focusing on latent variable models for psychometric data and longitudinal data. I also study the use and interpretation of effect size statistics more broadly. Some of the methods I'm interested in include exploratory and confirmatory factor analysis (especially with categorical data), structural equation modeling, latent growth curve models, and item response theory. I have applied these methodologies to research on a variety of topics in psychology.
