  • His laboratory made the discovery of serotonin as a key mediator of liver regeneration and pathogenesis of cancer (Science 2006).
  • Dr. Clavien has developed with the Wyss Zurich (Liver4Life) team a novel perfusion machine to extend the viability of liver tissue outside of the body up to one week. This technological advance will make it possible to treat the liver before transplantation and should save the lives of many patients with severe liver diseases and formerly inoperable liver cancers in the future (Nature Biotechnology 2020).
