In 2016, Karl received his Master degree at the University of Stuttgart. His thesis on the retrotranslocation process of proteins within the endoplasmic reticulum associated degradation (ERAD) was prepared at the Brodsky Lab in Pittsburgh, Pennsylvania US. Following up on this research, Karl worked as PhD student in the Wolf Lab in Stuttgart. In 2019 Karl started working at Alexandra’s Lab as a postgraduate researcher. He worked on different projects including the coordination of autophagy and ERAD, as well as the effect of Hypoxia on tumour cells. Recently Karl’s focus changed to following his joy and talent to summarize scientific findings in appealing and easy-to-catch illustrations. He currently supports members of IBC2 by designing or upgrading scientific illustrations for internal and external usage.
