Robert Alan Greevy, Jr, PhD

I am currently Director of the Biostatistics Graduate Program and Director of Health Services Research, Biostatistics. I teach the first year graduate course 'Principles of Modern Biostatistics'. My statistical methods research interests include: restricted randomization methods and sample size adaptive randomization for clinical trials, inverse probability weighted and doubly robust estimators, sensitivity analyses for unmeasured confounding, and foundational tools for better statistical inference. My medical research interests include: comparative effectiveness of anti-hyperglycemic medications in an EHR derived cohort of 400 thousand veterans with type 2 diabetes, effects of acute kidney injury in an EHR derived cohort of 17 million veterans, and randomized controlled trials for smoking cessation and for diabetes management.
