The Organoid Engineering Lab develops human stem cell (hESC) and induced pluripotent stem cell (iPSC)-derived organoid, assembloid, and organ-on-a-chip systems, applying them to address complex biological questions in disease modeling. We work closely with POEM-associated groups across the Heidelberg research campus, the University Hospital Mannheim, and the German Cancer Research Center (DKFZ), integrating biology with interdisciplinary approaches.
The following full-time (39,5h/week) position in stem cell-derived organoid research is available at the Cellnetworks Core Technology Platform of Heidelberg University, to begin as soon as possible:
