Marvin obtained his bachelor’s and master’s degrees in chemistry at the University of Freiburg. Within the THERADNET network, Marvin’s research aim is to investigate the energy metabolism of healthy and tumor brain cells using recently developed fluorescent biosensors which allows measuring metabolic parameters in vivo and in real-time. Simultaneously, millimeter-scaled tumor irradiation will be performed to better understand the effect of ionizing radiation on the energy metabolism of tumor cells. For the first time, the team will provide a real-time readout of ionizing radiation (and anti-tumor drugs) on critical parameters of energy metabolism. This hybrid method coupling ionizing radiation and real-time imaging of metabolic substrates is expected to significantly advance the knowledge of tumor biology and therefore provide knowledge to increase radiotherapy efficiency.
