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 BrayJohn Dziak, and Megan Patrick. 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 Sara Vasilenko, addresses new research questions about age- and time-varying effects related to health behavior.
