Collin J. Weber, MD, is William C. McGarity Professor of Surgery in the Department of Surgery at Emory University School of Medicine. Dr. Weber also serves as the Director of the Elizabeth Brooke Gottlich Diabetes Research and Islet Transplant Laboratory at Emory University, which has received significant funding for its efforts to make islet transplantation a viable cure for patients with Type 1 diabetes and to increase the supply of donor islets.


Dr. Weber graduated from the College of Physicians and Surgeons at Columbia University in New York in 1971. He completed his General Surgery Residency at Columbia University, and Columbia Presbyterian Medical Center in 1978. His Fellowship/Advanced Training includes a Doctor of Medical Science and as a NIH Postdoctoral Research Trainee in Surgery at Columbia University from 1973-1978, both at Columbia.


Dr. Weber's research interests include developing techniques for safe and durable pancreatic islet transplantation for patients with insulin dependent diabetes mellitus, the focus being the use of xenogeneic tissues as sources of donor islets and microencapsulation plus selective immune modulation of hosts to accomplish cross species islet graft survival. He also investigates the causes and functional characteristics of human parathyroid tumors by examining secreted products of human parathyroid tumors including neuropeptides and cytokines and analyzing replication of parathyroid tumors of differing histopathologies.
