Job Advertisement Cluster of Excellence "Balance of the Microverse”

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 Prof. Sebastian Weis at the Cluster of Excellence "Balance of the Microverse” invites applications for a

Doctoral Researcher in Infection Biology (m/f/div)

commencing on January 1, 2026 or upon agreement. We offer a part-time position (65%, fixed-term position for 3.5 years) at the Leibniz-Institut für Naturstoff-Forschung und Infektionsbiologie (Hans-Knöll Institut) in Jena. In this project, the applicant will investigate how metabolism adapts during the early and late phase of severe bacterial infections aiming to identify novel therapeutic strategies that safeguard organ integrity and promote survival. The main research question is how the gut microbiome and its dynamic changes during infection can influence systemic host responses, particularly through the availability of energy substrates. The project will combine in vivo mouse models, specific manipulation of the gut microbiome, metabolic phenotyping, molecular biology and immunology techniques, and integrative longitudinal metabolomics.

Your responsibilities:

• Perform in vivo and in vitro experiments with life pathogens and work independently towards your doctoral research project

• Analyse project results, generate figures for publications, and write scientific manuscripts for publication • Present your results at local, national, and international meetings and conferences

• Work closely together with other experimental and computational researchers in the research group and within the Cluster • Assist with training and supervising other researchers (e.g. student assistants, BSc students)

• Contribute to the friendly, welcoming, and collaborative environment in our team

Your profile:

• MSc in biological sciences / microbiology / immunology / biochemistry or closely related disciplines. Candidates in the final stages of obtaining their MSc are encouraged to apply

• Laboratory experience with in vivo experiments, immunology and microbiome is desired

• Strong enthusiasm for collaborative, interdisciplinary research in the described field • Excellent communication skills in English (written and spoken).

• An outstanding level of curiosity, self-motivation, dedication and enthusiasm to detail

• A cooperative personality actively seeking to contribute to our interdisciplinary and inclusive Microverse community Are you not applying because you think that you don't meet one or some of our requirements? Please do not hesitate to apply and give us a chance to get to know you.
