Stephanie's career is devoted to advancing prevention research in behavioral health through the development and application of innovative quantitative methods. She works primarily in two methodological areas. Much of her work seeks to advance finite mixture models, particularly latent class analysis. Her primary collaborators in this work include Bethany Bray, John Dziak, and Megan Patrick.
She also is working to advance and apply new statistical models in order to reveal dynamic processes. Much of this work, done in collaboration with time-varying effects related to health behavior., , and , addresses new research questions about age- and
Her interests include:
- Substance use behavior among adolescents and young adults
- Finite mixture modeling, including innovations in latent class analysis so that researchers can discover and understand hidden subgroups in their data
- Time-varying effect models to study substance use behavior developmentally and in real time/daily life
- Leveraging new technologies and methods to understand substance use behaviors in daily life based on intensive longitudinal assessment
