About Me

A. Osama Gaber, MD, is presently the Chair of the Department of Surgery at Houston Methodist Hospital, the J.C. Walter Jr. Presidential Distinguished Endowed Chair, and Director of the Houston Methodist J.C. Walter Jr. Transplant Center.  Dr. Gaber is also Professor of Surgery, Weill Cornell Medical College, Program Director, Abdominal Multi-Organ Transplantation Fellowship and Senior Member of the Houston Methodist Research Institute. 

After he earned his medical degree from the Ainshams University School of Medicine in Cairo, Egypt, he completed a residency in general and pediatric surgery.  He, subsequently, completed surgical training in general surgery at the Boston University Medical Center and a research clinical transplant fellowship at the University of Chicago.

Dr. Gaber has devoted much of his career to pancreas, liver, and kidney transplantation and the surgical care of organ failure patients.  He has been funded by the NIH, JDRF, Assisi Foundation, Vivian Smith Foundation, and many other national and local foundations.  He is the author of more than 270 papers, as well as more than 340 abstracts and numerous book chapters. Dr. Gaber founded Nora’s Life Gift Foundation to build Nora’s Home, a hospitality house, located in the Houston, Texas Medical Center for transplant patients and their families.  Nora’s Home offers transplant patients and their families an affordable place to stay where they can find support and share experiences with others, in the comfort of a home-like environment.
