Justin B. Dimick

Justin B. Dimick serves as the Frederick A. Coller Distinguished Professor of Surgery and Chair of the Department of Surgery at the University of Michigan, with a concurrent professorship in Health Management and Policy. As an active general surgeon, he specializes in advanced laparoscopic procedures including bariatric surgery, hernia repairs, and benign esophageal disease.

His educational foundation includes a BA in Biology from Cornell University (1995), an MD from Johns Hopkins University (2000), and an MPH from Dartmouth Medical School (2005). This multidisciplinary training underpins his dual expertise in clinical surgery and health policy analysis.

Dr. Dimick's research program focuses on surgical quality measurement, healthcare policy evaluation, and large-scale quality improvement initiatives. His work critically examines disparities in surgical care, economic impacts of hospital consolidation, and evidence-based adoption of robotic technologies. With over 450 peer-reviewed publications in journals like NEJM, JAMA, and Health Affairs, he bridges clinical practice with population health perspectives.

Analysis of his recent publications reveals consistent emphasis on healthcare system transformations—including private equity acquisitions, rural hospital closures, and value-based payment models—and their impacts on surgical outcomes. His scholarship increasingly integrates video-based surgical assessment and leadership development frameworks for complex healthcare environments.

His scientific recognition includes election to the National Academy of Medicine (2020):

• National Academy of Medicine (2020)

As an educator, Dr. Dimick has mentored 11 K-award recipients (5 currently active) and directs an NIH T32 grant for surgeon-scientist training. His sustained R01 funding from AHRQ and NIH supports investigations into surgical quality metrics and policy interventions. Leadership roles include past presidency of the Association for Academic Surgery, NIH HSOD Study Section chairmanship, and editorial positions at Annals of Surgery and JAMA Surgery.

He actively contributes to national discourse through leadership in the American Surgical Association, Society of Clinical Surgeons, and American Society of Clinical Investigation, shaping surgical policy and education standards.
