Biostatistical analysis of health data, latent variable modeling, modern missing data (e.g., pattern and selection models), longitudinal analyses (GEE, latent growth)
My primary research interest is in the innovative application of modern latent variable methodologies to assist scientists to better answer a variety of research questions. Specifically, I am interested in the innovative application of modern missing data methodologies (e.g., pattern-mixture modeling, Diggle-Kenward selection modeling) and longitudinal methods of analysis (i.e., finite growth mixtures, generalized estimation equations, latent growth curve modeling, and multilevel modeling) to substance abuse clinical trial data.
