Research Interests & Collaborators

I work primarily in two methodological areas. Much of my work seeks to advance finite mixture models, particularly latent class analysis. My primary collaborators on this project include Bethany Bray and John Dziak. I also work to advance and apply new statistical models in order to reveal dynamic processes. Much of this work, done in collaboration with Runze LiMichael Russell, and Ashley Linden-Carmichael, addresses new research questions about age- and time-varying effects related to health behavior. Much of my applied research uses intensive longitudinal data to examine substance use in daily life.
