• Postdoc (m/f/d) in Endosymbiosis Research
• Job-ID: J000000668
• Working hours: Full time
• Location: Düsseldorf
• Start date: 01.01.2027
• Limited until: 31.12.2028

• Organization: MathematischNaturwissenschaftliche Fakultät
• Job Category: science / research / teach To support our ongoing research, we are seeking a highly motivated Postdoctoral Researcher to join our team. Our group is an enthusiastic and collaborative team of cell and evolutionary biologists investigating the evolutionary transition from bacterial endosymbionts to eukaryotic organelles. We seek to understand, at the mechanistic level, how protists interact with permanent bacterial endosymbionts and how these associations evolve toward organellogenesis. To address these questions, we combine state-of-the-art omics approaches with detailed molecular biological and protein biochemical experimentation. As model systems, we have established the photosynthetic amoeba Paulinella chromatophora and the symbiont-harboring trypanosomatid Angomonas deanei and related species in the laboratory. Our work has provided exciting insights into organellogenesis and enabled us to develop novel tools for dissecting the molecular and cellular biology of host-symbiont interactions (see e.g., Morales et al. (2023) Curr Biol. doi: 10.1016/j.cub.2022.11.020.; Sørensen et al. (2024) FEBS J. doi: 10.1111/febs.17356; Maurya et al. (2025) Science Adv. doi: 10.1126/sciadv.adp8518; Klimenko et al.

The successful candidate will contribute to a current project at the heart of our research program, with the opportunity to shape the project in part according to their scientific interests, expertise, and strengths. The position will also involve a limited amount of undergraduate teaching in German [4 contact hours (Semesterwochenstunden) per week], providing an opportunity to contribute to the training of the next generation of biologists.
