I am a professor in the Quantitative Methods (QM) program at Vanderbilt University. Broadly speaking, I am interested in bridging the gap between theory construction and model specification and assessment. Much of my research involves finding ways to apply multivariate statistical techniques to address complex hypotheses with longitudinal and correlational data. Specific interests include factor analysis, structural equation modeling (SEM), multilevel modeling (MLM), latent growth curve modeling (LGM), model fit, and the assessment of mediation and moderation effects.
My research interests have recently extended to include multilevel structural equation modeling (MSEM), an emerging paradigm that combines the strengths of MLM and SEM.
Multilevel Modeling: A Second Course. A two-day seminar sponsored by Statistical Horizons, to be held December 9-10 in Philadelphia, PA.
