Research intrests

My research focuses on statistical methods for missing and multilevel (or clustered) data. I am interested in the following areas: Bayesian computational algorithms and software development, hierarchical and latent variable models, models and methods for response errors, and analysis of large observational datasets. Most of my research is motivated by methodological issues in public health research, prevention research and health services research.
