I use statistics to facilitate clinical and health services research across a spectrum of disciplines and specialties. This work has been reported in over 280 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. Recently I have been studying the association of government spending with reduced mortality in order to help explain the stagnation of American longevity.
