The Institute of Microbiology seeks to fill the position of a
Doctoral or Postdoctoral Researcher
commencing on 01.12.2025 For a postdoctoral appointment we offer a full-time position, initially as a fixed-term position until 30.11.2027.
For a doctoral appointment we offer a part-time position (65%), initially as a fixed term position until 30.11.2028.
The Theoretical Microbial Ecology research group, led by Prof. Rosalind Allen, is part of the Faculty of Biological Sciences at the Friedrich Schiller University. The group seeks to understand how microbes survive, grow and interact in complex and changing environments. The group is especially interested in how microbial communities assemble and function and how bacteria respond to antibiotics in the human body. To study these topics the group combines computational and theoretical models with lab experiments. Microbial communities are central in the stability and function of environmental and industrial ecosystems as well as in human, animal and plant health. Although we have advanced methods for probing the species composition of microbial communities, we are not yet able to predict their dynamics and stability. Mathematical models have a key role to play in understanding the complex compositional structure and dynamics of microbial communities. Several different modelling approaches are available, but it is unclear which approach is optimal. Testing against experimental data is important for validating existing models and developing new ones. The group of Prof. Miriam Rosenbaum at the Leibniz Institute for Natural Product Research and Infection Biology (Hans Knöll Institute) in Jena are collecting dynamical data on the community composition of microbial communities that are exposed to environmental disturbances. In this project, you will collaborate with Prof. Rosenbaum’s group to analyse these datasets and develop mathematical models that describe the dynamics of these communities and predict their response to disturbance. You may also collaborate with other experimental groups within the Microverse cluster, and with experimental researchers within the theoretical microbial ecology group, to develop models for the dynamics of diverse types of microbial communities. If desired, there is scope to combine your theoretical modelling with experimental work in our own microbiological lab.

• Conduct research within the broad topic area of the DFG-funded Excellence Cluster “Balance of the Microverse, using theoretical techniques including computer simulations.
• Specifically, develop theoretical models for microbial community dynamics and stability, as well as analysing microbial community dynamics datasets.
• Develop and modify code in languages such as python, c++, matlab etc.
• Produce and analyse results and interact productively with experimental data provided by external collaborators, including using experimental data as input to models.
• Contribute to the development of project direction, as the project evolves.
• Produce high-quality written reports and draft papers.
• Present your results at local meetings and national and international conferences, including participating actively in activities organised by the Balance of the Microverse Cluster.
• For a doctoral position, write a dissertation to obtain a doctorate at FSU Jena.
• Assist with training other researchers, including Masters’ and undergraduate project students, and, for postdoctoral candidates, also doctoral students,
• Assist with the teaching activities of the group where required.
• Contribute to maintaining the friendly, welcoming and collaborative environment within the group.
