Martin Hexamer studied electrical engineering at the Ruhr University Bochum (RUB), specialising in control engineering, measurement technology and data processing. After successfully graduating (Dipl.-Ing.), he worked as a research assistant at the Institute of Physiology (Department of Biocybernetics) of the RUB Faculty of Medicine. As part of his doctorate, he worked on the external regulation of body temperature in extreme situations.

After successfully completing his doctorate (Dr. rer. nat.), he moved to the newly established Department of Biomedical Engineering at the RUB Faculty of Medicine. Together with the former head of the department, he established several research areas. Martin himself focused on the fields of rate-adaptive pacemaker therapy and the automation of the heart-lung machine. He obtained funding from the German Research Foundation (DFG) for both research areas. His habilitation deals with the system-theoretical analysis of rate-adaptive pacemakers. Since 2010, he has been a member of the Chair of Medical Technology at the Faculty of Electrical Engineering and Information Technology (RUB). There he developed a pump drive and algorithms for blood gas control for a novel miniaturised heart-lung machine as part of two industry-related projects.

Martin is a member of the German Association of Electrical Engineers (VDE) and has been a member of the Ethics Committee of the RUB Faculty of medicine for more than twenty years. He is a regular reviewer for several international journals, the German Research Foundation (DFG) and the Bavarian Research Foundation.
