Professional Interests
I use statistics to facilitate clinical and health services research across a spectrum of disciplines and specialties. This work has been reported in over 290 publications. The majority of these projects involve comparative effectiveness, clinical trials, association studies, and prediction modeling. I am especially interested in survival (aka, time-to-event) analysis, and causal inference. Recent work includes studying the association of government spending with reduced mortality in order to help explain the stagnation of American longevity, and the quality and effectiveness of colonoscopy for colorectal screening and surveillance.
