The Helmholtz Institute for RNA-based Infection Research (HIRI), in collaboration with the University of Würzburg, is offering one PhD and one postdoctoral position focused on specialized metabolite functions during gut microbial interactions in Fusobacterium nucleatum . The research will be conducted in the laboratories of Professor Franziska Faber and Professor Jörg Vogel, with funding provided by the DFG Priority Program SPP2474, which aims to uncover new gene functions in members of the human microbiome. The project centers on identifying and studying the genetic regulation and functions of specialized metabolites during gut microbial interactions, with a particular emphasis on Fusobacterium nucleatum . Applicants are expected to have a strong background in molecular biology, microbiology, biochemistry, or computational science. The research environment at Würzburg offers a vibrant RNA and infection research hub, state-of-the-art technologies and facilities, an international and collaborative atmosphere, and a highly interdisciplinary environment. The institute also provides international visibility and access to the Single-Cell Center Würzburg. PhD applicants should hold an equivalent of a Master's degree. The positions are available for three years with the possibility of extension, and salary will be based on the public sector pay scale in Germany (TV-L). The university encourages applications from qualified women and handicapped persons, especially in cases of equal aptitude. To apply, candidates should email their application by January 11th, 2026, including a short letter of motivation, CV, publication list, copies of relevant documents and certificates, and contact information for two academic references in a single PDF file with the reference 'SPP2474' in the subject line to [email protected].
