The Working Group Environmental Biochemistry at the University of Oldenburg, Germany, is seeking an advanced postdoctoral researcher to carry out projects in natural products chemistry, ecotoxicology, and chemical ecology of marine invertebrates and associated microorganisms. We are seeking a motivated postdoctoral candidate with an academic university degree (master or equivalent) and a PhD in either Biology, Chemistry, Marine Environmental Science, or a related research field to join our team. The successful candidate will contribute to our ongoing scientific efforts and will have access to our large collection of tropical and deep-sea macro and microorganisms to discover potential new bioactive marine natural products. In addition, the candidate should have a strong background and extensive experience in marine natural products research, especially in running and maintaining high-resolution mass spectrometers. The candidate will be joining a team of chemical and microbial ecologists, chemists, and microbiologists at the ICBM in Wilhelmshaven. Working place is the ICBM in Wilhelmshaven.
