Project description:

Molecular evolution of cnidarian organelles
Our group at the Centre of Organismal Studies (COS), Heidelberg, focuses on the molecular evolution of extracellular matrix and signaling factors. We are working with the model organism Hydra, a member of the basal metazoan group of cnidarians, which is famous for its unparalleled regenerative capacity.
Here, we are looking for PhD student, who is interested in analyzing the evolutionary origin of collagen molecules and other ECM factors in the mesoglea and specialized organelles of Hydra. The offered project blends proteomic screens with high-resolution imaging of expression patterns and functional knock-down (siRNA, CRISPR/Cas) as well as biochemical studies.
The PhD position is fully funded by the DFG for 3 years and payment is according to TV-L.

Personal qualifications:
Experience in bioinformatics, molecular biology, protein biochemistry, and advanced light microscopy. Experience with cnidarian model systems is advantageous, but not compulsory. We are looking for a highly motivated and skilled candidate with genuine interest in evolutionary biology.
