Greg Nowak

Greg Nowak, MD, PhD, is an Adjunct Professor at the Department of Clinical Science, Intervention and Technology, Karolinska Institutet (2023-2026). He earned his Doctor of Philosophy from Karolinska Institutet's Center for Surgical Sciences in 2003 and became a Docent in 2006. His clinical base is at the Transplantation Surgery Unit, Hälsovägen, Stockholm, with postal operations managed through CLINTEC Transplantation in Huddinge.

Professor Nowak's research centers on surgical innovation in transplantation, with emphases on:

• Liver graft adaptation and volumetric dynamics
• Metabolic stress responses in hepatobiliary disorders
• Pediatric portal vein obstruction management
• Ischemia-reperfusion injury mechanisms
• Domino transplantation program efficacy

His work integrates clinical studies with biomarker validation to refine postoperative protocols.

His recent publications (2018-2023) demonstrate a consistent focus on transplant outcomes optimization, with recurring themes including retransplantation benchmarks, nutritional interventions post-transplant, microdialysis monitoring, and novel therapeutic approaches for metabolic liver diseases. Collaborative multinational registry studies feature prominently in his methodology.
