Biography & Projects

Stephanie Lanza'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 Ashley Linden-Carmichael.

She co-directs the Addiction and Innovative Methods (AIM) Lab with Ashley Linden-Carmichael, Assistant Research Professor of Health and Human Development.

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 Ashley Linden-Carmichael, addresses new research questions about age- and time-varying effects related to health behavior.

Stephanie also collects contemporary data on young adult substance use using intensive measurement via wearable devices. This work is designed to inform within-person risk factors for substance misuse and its consequences.
