Professional Experience

Stephanie's career is devoted to advancing research in behavioral health through the development and application of innovative quantitative methods. She focuses this work in two key areas. First, she works on extensions to latent class analysis, including multilevel latent class analysis, so that researchers can discover hidden subgroups or types of moments in their data and understand their antecedents and consequences. Second, she focuses on the application and dissemination of time-varying effect models, which enable scientists to examine regression coefficients as a continuous function of age or time, often using intensive longitudinal data.

Grants and Research Projects
