Latent variable modeling, modern missing data (e.g., pattern and selection models), longitudinal analyses (GEE, latent growth), psychopharmacology and substance abuse, nephrology My primary research lines include 1) development of evidence-based substance use disorder treatments, 2) innovative analytical methods to answer research questions in psychopharmacology and substance abuse, and 3) substance use disorder as a complicating co-morbidity.
