Professional Interests

My research interests span both statistical methodology and various areas of medicine and health care. My prior and ongoing contributions to statistical methodology involve statistical inference for social networks, multivariate hierarchical models, comparative effectiveness research including causal inference for both randomized and observational studies, and Bayesian analysis. Specific research projects are typically motivated by problems encountered in my collaborative work with physicians, sociologists, health economists, health services researchers, epidemiologists and others. Application areas of focus include evaluating the relationship between health and social networks, evaluation/estimation of variations in health quality and outcomes, vascular surgery and cardiology, and evaluation of medical devices.
