MAJOR PROFESSIONAL INTERESTS

· Measuring Change over Time. I have a career-long interest in the development and application of statistical methods for modeling individual change and multi-level modeling, for measuring individual change over time, and for investigating inter-individual differences in learning and development.

· Analyzing the Occurrence, Timing, and Duration of Events. I seek to promote the application of event history methods in the analysis of event occurrence, timing, and duration in education and the social sciences. I am particularly interested in, and have developed and disseminated, strategies for the discrete-time hazard modeling of single and multiple-spells.

· Modeling Covariance Structures. I maintain a general interest in the application of covariance structure methods to research problems in education and the social sciences. I have a specific interest in using these techniques for latent growth and multi-level modeling.

· Designing and Implementing Better Longitudinal Empirical Research. I seek to promote more thoughtful empirical research design and more careful application of innovative quantitative analytic methods, particularly in the collection and analysis of longitudinal data, in education and the social sciences.

· Improving the Teaching of Applied Statistics. I am interested in devising and promoting better ways of teaching quantitative methods, particularly pedagogies that engage students in authentic activities, apprenticeship, and the analysis of real data.
