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, instrumental variables,joint modeling of survival and longitudinal patient outcomes, and randomization in learning health systems.
