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, Brittany Rhoades Cooper, 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 Li, Sara Vasilenko, and Megan Piper, addresses new research questions using intensive longitudinal data related to drug abuse.
