Offer Description

GEOMAR Helmholtz Centre for Ocean Research Kiel is a foundation under public law jointly financed by the Federal Republic of Germany (90%) and the State of Schleswig-Holstein (10%). It is one of the internationally leading institutions in the field of marine research.

Through our research and our commitment to the transfer of knowledge and technology, we contribute significantly to the preservation of the function and protection of the ocean for future generations.

In the frame of the BlueHealthTech project MarPiM, funded by the BMBF as part of the WIR! Program, GEOMAR Research Unit Marine Natural Products Chemistry / GEOMAR Centre for Marine Biotechnology is seeking an experienced

Post-doctoral researcher(m/f/d)

in Fungal Biotechnology / Fungal Natural Product Chemistry

starting at the earliest date possible.

Project Description

BlueHealthTech links competencies in Kiel area in marine research (Blue), health care and industry (Health) to generate novel technological approaches to improve the diagnosis, monitoring and treatment of chronic diseases. The program exploits the regionally available technical and analytical knowledge for sustainable development of innovative health technologies (Tech) in new multidisciplinary partnerships.

Marine fungi have high biosynthetic capability for producing novel and bioactive secondary metabolites with pharmaceutical relevance. The main aim of the BlueHealthTech-funded project MarPiM is to assess preclinical efficacy and development potential of marine fungal natural products against skin cancer by using state-of-the-art methods of fungal biotechnology, marine natural product chemistry, multi-omics, bioanalytics and innovative imaging techniques.

Job Description

We are seeking a highly skilled post-doctoral researcher with demonstrated expertise in large scale microbial fermentation and downstream natural product chemistry. The candidate will initially optimize the upscaled fermentation (300 L) of target marine fungi and extract the fungal broth. This will be followed by i) LC-MS/MS-based untargeted metabolomics analysis, ii) mass spectrometry- and bioactivity-guided isolation and iii) structure elucidation of anticancer fungal metabolites. The candidate will work closely with project partners at Kiel University for determination of in vivo efficacy and mechanism of action of the target molecules. The candidate will actively manage the project and related administrative tasks. He:She will be  expected to write publications/patents/project reports and contribute to assessment of project results for potential development.

This is a unique opportunity for an ambitious post-doctoral researcher to further develop their career on microbial drug discovery and development that can make impact on human life.

Working language in the group is English.
