The Centre for Organismal Studies Heidelberg (COS Heidelberg) is a central scientific institution of Heidelberg University with 23 research groups representing the entire breadth of the life sciences in research and teaching. The following position (full time (100%, 39,50 hrs/week), limited to the end of 2026) is now available in the research group Stem Cell Niche Heterogeneity of Dr. Josephine Bageritz.

The Bageritz lab is looking for a motivated cell and molecular biologist to support the continued development of the laboratory and to contribute to an engaged and cooperative team culture. Our group uses and develops cutting-edge single-cell imaging and spatial transcriptomics techniques to gain insights into the molecular mechanisms that drive cell fate, tissue patterning, and skeletal muscle development, with a particular focus on understanding muscle stem cell biology and their fate decisions.
