With the support of an exchange program developed by Boston College economists Tayfun Sönmez and Utku Ünver, the Banu Bedestenci Sönmez Liver Paired Exchange System has rapidly become one of the world’s leading liver exchange initiatives.

Located at Turkey’s Inonu University, the program has set new standards by performing the world’s first five-way liver exchange in October 2023, the first six-way liver exchange last January, and the first seven-way liver exchange in July, said Sönmez. These groundbreaking procedures have been documented in a forthcoming paper in the American Journal of Transplantation, the premier scholarly outlet for the field.
