The Friedrich Schiller University Jena is a dynamic and innovation-driven university centrally located in Germany. With a broad range of disciplines, it shapes the future through excellent research and teaching. Its scientific excellence is reflected in the profile areas Light – Life – Liberty, which provide pioneering insights and sustainable solutions for the society of tomorrow. Through close collaborations with leading research institutions, innovative companies, and renowned cultural organizations, it advances interdisciplinary developments. With around 17,000 students and approximately 10,000 employees, it defines Jena as a vibrant, internationally connected city of science and innovation.

The Cluster of Excellence “Balance of the Microverse” studies the fundamental principles underlying microbial community interactions and functions in diverse habitats, ranging from oceans and groundwater to plants and human hosts. We integrate insights across ecological and medical fields to enhance our understanding of microbial balance from the molecular to the ecosystem level. We develop tools and detection technologies to shape microbiome dynamics for environmental and human health benefits. The affiliated early career program of the Jena School for Microbial Communication offers an ambitious, structured and interdisciplinary post-graduate training based on top-level fundamental research.

The research group of Dr. Kathrin Fröhlich (https://www.bio.uni-jena.de/en/18326/bacterial-rna-biology ) at the Cluster of Excellence “Balance of the Microverse” invites applications for a

Doctoral Researcher in Bacterial RNA Biology

commencing on December 1, 2025 or upon agreement. We offer a part-time position (65%, fixed-term position for 3 years) at the University of Jena.

The rapid spread of resistances to antibiotics is threatening global health, and Klebsiella pneumoniae plays a major role in this crisis. In bacteria, the SOS pathway to DNA damage is activated by many antibiotic compounds and plays a central role in promoting survival and the evolution of resistance under antibiotic stress. We recently identified a rich landscape of regulatory RNAs in K. pneumoniae (Ruhland et al. 2024 PNAS) and now aim to define the species-specific contribution of post-transcriptional regulation to the SOS program. The successful candidate will perform transcriptome analyses, map RNA-RNA interactions and dissect the role of individual sRNAs and RNA-binding proteins in response to DNA damage.
