Professional Interests:

My current research interests revolve around challenging methodological and statistical problems in biomedical data science. I collaborate extensively in the areas of cancer and musculoskeletal disease involving clinical, translational and outcomes research. I develop related statistical methodology in the areas of covariate measurement error for nonlinear regression models, clinical trials, and joint modeling of survival and longitudinal patient outcomes.
