Research Interests & Collaborators
I am interested in most aspects of research methods. Lately I have been most interested in experimental and non-experimental design, particularly for building, optimizing and evaluating behavioral interventions. I also have a long-standing interest in models for longitudinal data, particularly latent transition analysis, and other latent class models. I am working on two related projects to bring ideas from engineering to bear on optimization of behavioral interventions. My collaborators on these projects are Daniel E. Rivera (Arizona State University), Runze Li, Inbal Nahum-Shani (University of Michigan), John Dziak, and Susan Murphy. I also collaborate frequently with Stephanie Lanza on research related to latent class and latent transition analysis.
