Marten Szibor, MD (male, b. 1971) is a clinician scientist with strong expertise in molecular genetics and physiology, particularly mitochondrial biology, and the use of alternative respiratory enzymes such as alternative oxidase (AOX) to challenge disease paradigms. After completing his doctorate in 2001 and postdoctoral fellowships in Germany and Switzerland, he was appointed as a research associate at the Max Planck Institute for Heart and Lung Research in Bad Nauheim, Germany. In 2013, Marten moved to Helsinki, Finland, to join Howy Jacobs’ lab as a senior researcher to further expand the field of AOX research based around mouse models he had created in Bad Nauheim. In 2019, Marten relocated to Germany and has since been a researcher at the Department of Cardiac and Thoracic Surgery at Jena University Hospital. Marten is an active member of the German Society for Gerontology and Geriatrics (DGGG), the German Physiological Society (DPG), the European Association for Cardio-Thoracic Surgery (EACTS) and the German Cardiac Society (DGK).
