Dr. Joseph Gassner focuses on small animal models of normothermic ex vivo liver machine perfusion (NEVLP) for high throughput establishment of transferable protocols for reconditioning of grafts from extended criteria donors (ECD). As a resident at the Department of Surgery, he started his clinical education in 2017. After having worked as research fellow in the DFG-funded project “Defatting of steatotic liver grafts by ex vivo machine perfusion with DNP [DeFat]” headed by Priv.-Doz. Dr. med. Nathanael Raschzok, he applied successfully for the Junior Clinician Scientist Program of the Berlin Institute of Health (BIH) with the project “Normothermic extracorporeal gen modification of the liver”.
