Research Interest
Dr. Dunn is a Professor of Medicine. In collaboration with colleagues of the Thomas E Starzl Transplantation Institute and the School of Health and Rehabilitation Sciences, he leads a UPMC hospital-funded initiative to improve the fitness and activity of liver transplant candidates with the objective of producing a 20% decrease in waitlist hospital days and waitlist mortality. Wearable personal activity monitoring and quantitation of muscle mass with imaging segmentation analysis are being explored as enabling technologies.

Dr. Dunn formed and now leads the FLEXIT (Fitness, Life Enhancement and Exercise in Transplantation) Consortium of investigators at the University of California San Francisco, Mayo Clinic Arizona, Cleveland Clinic, Duke University, University of Alberta, and University of Pittsburgh, engaged in multi-center collaborations to define, prevent and reverse physical decline in cirrhosis.

Dr. Dunn helped Dr. David Binion design and continue to assist in operating a Department of Defense supported searchable prospective electronic clinical registry for our inflammatory bowel disease team. It has enabled significant advances in disease modeling with over 20 major publications in the last 3 years.

He also serves as the site Principal Investigator of an industry-sponsored FDA registration trial of obeticholic acid therapy for primary sclerosing cholangitis.
Clinical Interest
I am a hepatologist and Associate Chief for Translational Research of the Division of Gastroenterology, Hepatology and Nutrition. My major current interest is understanding, preventing and reversing physical decline and muscle wasting in cirrhosis, the major cause of death and waitlist attrition in liver transplantation. I am experienced in analysis of data from electronic records for improved predictive modeling and decision support.
