2022 TTS Thomas Starzl Innovation Award Recipient

Professor Jan Paul Marthe Lerut

The TTS Starzl Innovation Award is named after Tom Starzl who was best known for his contributions to the field of organ transplantation, and often referred to as the “father of transplantation”. The award recognizes individuals who, though advanced and original work, have contributed significantly to transplantation, thereby reflecting the spirit pioneered by Dr. Starzl.

Professor Jan Lerut has dedicated his professional life to transplant surgery, particularly liver and hepatobiliary surgery. In 2005, he founded the Starzl Transplant center in Brussels, Belgium. Under Professor Lerut’s leadership, the center has performed more than 2500 liver transplants (1,500 adults and 1,000 children) in addition to 4,000 kidney transplants.

Professor Lerut will deliver his acceptance speech during the President's Plenary session on Wednesday, September 14 during our TTS 2022 Congress being held in Buenos Aires from September 10-14, 2022.
