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.
Rotations and Thesis Projects:
- Analysis of Social Network Data
- Multivariate-Multilevel Models
- Comparative Effectiveness Research (Causal Inference)
- Bayesian Analysis
- Design and Analysis of Medical Device Clinical Trials
- Social networks and health
- The measurement and reporting of health care quality
- Diffusion of medical technology
- Tracking health systems
- Comparative effectiveness in vascular surgery
- Comparative effectiveness in cardiology
- Comparative effectiveness in mental health

In 2011 I received the Mid-career Excellence award from the Health Policy Section of the ASA and in 2012 became an elected fellow of the ASA. In 2019 I was the recipient of the International Society for Pharmacoeconomics and Outcomes Research (ISPOR) Award for Excellence in Methodology in Health Economics and Outcomes Research.
I was chair of the Health Policy Statistics Section of the America Statistical Association (ASA) in 2008, co-chair of the 2011 International Conference on Health Policy Statistics, and am an Associate Editor at Statistics in Medicine.
I was one of the organizers of the Dartmouth Interdisciplinary Network Research (DINR) seminar series (http://www.dartmouth.edu/~dinr/).
