We are seeking, to start as soon as possible, two part-time (65%) fixed-term

Research Associates (m/f/d)

in Evolution, Genomics and Cell Biology of Algae

The position is for 65% of a full-time workload (currently 25.35 hours per week) and is limited to a term of three years. The fixed-term appointment is based on the provisions of the German Act on Fixed-Term Employment Contracts in Academia (WissZeitVG). Further academic qualification (Ph.D.) is part of the job responsibilities and is strongly encouraged.

The positions are in the field of evolution, genomics, and cell biology of algae within the Aquatic Ecosystem Analysis research group at the Institute for Integrated Natural Sciences, Biology, in Division 3: Mathematics/Natural Sciences.

How do new photosynthetic organelles arise, and how are they permanently integrated into a eukaryotic cell? In a newly discovered photosynthetic single-celled organism, we are investigating an unusually complex plastid whose evolutionary origin and cellular integration have so far remained largely unclear. This system thus offers a rare opportunity to study key processes of the evolution and integration of photosynthetic organelles in a living organism. Preliminary genomic and ultrastructural data suggest that the plastids arose from a complex endosymbiosis with an alga.

At the heart of the project is a yet-to-be-named unicellular alga from the Cercozoa. Two closely linked doctoral projects are jointly investigating the evolutionary origin of the plastids. One of the projects focuses on genomic adaptations, while the second, primarily using microscopy, examines the cellular integration and functional properties of the plastids. To this end, we combine modern genomics and phylogenomics with bioinformatic analyses, cell culture, and light and electron microscopy techniques. Among other things, we are investigating the genomes of the host cell and the plastid, the transfer and origin of plastidial genes and proteins, as well as the architecture and inheritance of plastids within the cell.

Both positions combine experimental work in the wet lab with the analysis of genomic and microscopic data, offering scope for diverse research focuses in the fields of algae evolution, genomics, and cell biology.

The doctoral projects are based in the Aquatic Ecosystem Analysis research group, are closely coordinated, and are designed to last three years. Further information about the research group can be found at .

The University of Koblenz welcomes applications from people of all ages, regardless of gender identity, disability, ethnic or cultural background, religion, worldview, or sexual orientation. We strive to increase the proportion of women in our workforce and are therefore particularly interested in applications from women.

In cases of equal qualifications and competence, women will be given preferential consideration if they are underrepresented. People with severe disabilities will be given preferential consideration if their professional and personal qualifications are otherwise equal.

For further information, please contact the two project leaders, Prof. Dr. Kenneth Dumack ( kenneth.dumack@uni-koblenz.de ) and Dr. Jule Freudenthal ( jule.freudenthal@uni-koblenz.de ).

Please submit your complete application materials (cover letter, resume detailing your academic and research background, and copies of relevant degree certificates) by 22.11.2026 , citing reference number 110/2026 , exclusively via email as a single PDF file to bewerbung@uni-koblenz.de . Please briefly explain in your cover letter which of the two research areas “Evolution and Genomics of Plastids” or “Cell Biology and Microscopic Investigation of Plastid Integration” you are particularly interested in. Applications expressing interest in both research areas are expressly welcome. Please do not submit application photos. Upon completion of the selection process, the application materials will be destroyed in accordance with data protection regulations.
