This research focus builds on the Cluster of Excellence Balance of the MicroverseExternal link and unites experts from five faculties. It investigates how microbial balance emerges, becomes disturbed and can be restored, the role of chemical signals in these processes, and how such signals affect microbial infection mechanisms. The focus bridges molecular mechanisms, disease processes, and systemic interactions. The interdisciplinary approach links microbiology, chemistry, physics, medicine, and data sciences. Cutting-edge methods such as multi-omics, high-resolution imaging, organ-
on-chip systems, and AI-based modelling enable analyses from molecules to ecosystems.

  • Microbial and chemical signalling

    Microorganisms shape ecosystems and host funtioning. Chemical mediators regulate microbial community composition, stability, and resilience, influencing cooperation, competition, and tipping points - relevant for both health and the environment.

    Microbial and infection biology
  • Infection biology

    Microbiome disturbances promote infections. Research focuses on fungal, bacterial, and viral diseases to elucidate molecular mechanisms and develop new diagnostics, microbiom-based therapies, and antimicrobial strategies. Studies address antimicrobial compounds, resistance mechanisms, and natural product biosythesis, using synthetic biology to prevent infections. Integration with clinical and technological partners fosters translational concepts and personalised medicine.
