At the Digestive Surgery Research Laboratory, we are fortunate to have researchers from across the United States and abroad who share our enthusiasm and commitment to transform patients' lives through medical research. Their desire for knowledge and understanding drives them in their quest to prevent, better manage, and, one day, cure digestive diseases. As they painstakingly unravel the mysteries of digestive diseases, they are forging new pathways of discovery. 



The Price Institute of Surgical Research funds one or two "Price Fellows" each year so that they may obtain a doctorate in philosophy (Ph.D.) while conducting research in the Digestive Surgery Research Laboratory. To learn more about our current research please view our publications. The Digestive Surgery Research Laboratory is located in the Medical Dental Research Building on Floyd Street within the Price Institute for Surgical Research.    

 Our laboratory focuses on basic molecular research into gastrointestinal diseases including: 

  • Crohn's Disease
  • Ulcerative Colitis
  • Colorectal Cancer



We encourage teamwork—both in the laboratory and in collaboration with researchers at regional, national and international institutions. Together, we apply our expertise to statistical analysis, pathological interpretation, and genetics research.



Our clinical research fellows have access to, and gain experience with, the latest drugs as well as surgical techniques for digestive disorders. This unique focus on medical and surgical treatments allows us to offer some of our patients the opportunity to participate in clinical trials of new medications or to take advantage of new surgical procedures for inflammatory bowel disease and colorectal cancer.
