Matt Maciejewski, PhD is a Professor in the Department of Population Health Sciences. He is also a Senior Research Career Scientist and Director of the Non-randomized Design Lab in the Center of Innovation to Accelerate Discovery and Practice Transformation at the Durham VA Medical Center. Matt also holds Adjunct Professor appointments in the Schools of Public Health and Pharmacy at the University of North Carolina at Chapel Hill.

He has received funding from NIDA, CMS, AHRQ, VA HSR&D, and the RWJ Foundation to conduct evaluation of long-term clinical and economic outcomes of surgical interventions, behavioral interventions and Medicare program or policy changes on patients with obesity and cardiometabolic conditions.  He is also interested in methods for addressing unobserved confounding in observational studies.  Matt evaluated the first-ever population-based implementation of value-based insurance design and led the first-ever linkage of lab results and Medicare FFS claims.  He has published over 250 papers in peer-reviewed journals such as JAMA, JAMA Internal Medicine, JAMA Surgery, Annals of Internal Medicine, Health Economics, Medical Care, Health Services Research, Journal of Clinical Epidemiology and Diabetes Care.
