Postdoctoral position in rhizosphere chemical ecology and secondary metabolite networks
You will investigate how soil microorganisms biotransform secondary metabolites and how these transformations influence microbial interactions and community assembly. Using simple synthetic microbial communities (SynComs), the project will explore the fate of microbial and plant-derived metabolites in soil and their role in mediating chemical communication between microorganisms. The work will combine microbiology, microbial ecology, and metabolite analysis to uncover fundamental mechanisms governing microbial interactions in soil ecosystems. You will be part of the research teams of Associate Professor Lars Behrendt and Professor Lars Jelsbak. The Behrendt group investigates how individual microorganisms and microbial communities respond to environmental changes, with a particular focus on microfluidic model systems. The Jelsbak group focuses on soil and rhizosphere microbial ecology, specifically the roles of microbial secondary metabolites and their potential applications in biocontrol. This position is part of the Center for Excellence in Microbial Secondary Metabolites (http://www.cemist.dtu.dk), led by Professor Lone Gram, where you will join a world-leading team at the forefront of microbial secondary metabolite research. You will collaborate closely with microbiologists, natural product chemists, and bioinformaticians in a dynamic, creative, and stimulating environment. Our recently renovated laboratories are equipped with state-of-the-art technology for high-content imaging, bacterial molecular research, and analytical chemistry. While the Postdoc project focuses on secondary metabolites in natural systems, the CeMiSt center also applies this fundamental research to the development of novel medicinal drugs. Responsibilities and qualificationsWe are seeking an enthusiastic and self-motivated candidate with a background in microbiology or natural product chemistry, and a strong interest in bacterial interactions and secondary metabolites. The ideal candidate is passionate about exploring the microbial- and plant derived secondary metabolites and their role and fate in ecology of soil microbiomes, with a particular focus on how secondary metabolites facilitate microbial interactions. You should be excited by the opportunity to leverage novel tools and analytical methods to investigate the role, fate and function of microbial secondary metabolites. The role requires good organizational skills, a structured approach to work, and a collaborative spirit. You will enjoy engaging with a multidisciplinary team, including PhD students and postdocs, and contribute to a positive team environment. A good sense of humor is always appreciated! Preferred qualifications include experience in the following areas: A PhD in microbiology, biotechnology, microbial ecology, or a closely related area. A good publication record demonstrating research excellence in areas relevant to microbial and microbiome-based solutions, including microbial chemical ecology and molecular microbiology. A strong background in studies of the function and/or fate of microbial secondary metabolites in microbial communities. Experience in developing and applying experimental model systems such as synthetic communities to investigate complex microbial communities. Expertise in studying microbial interactions, integrating chemical, molecular, and community-level approaches to link mechanisms with ecological outcomes. Experience with interdisciplinary research and collaboration across scientific domains. Experience with teaching and supervision at the university level, or clear potential to develop high-quality teaching skills. Strong written and oral communication skills in English. Good English language skills are essential. The main criterion for selection will be the research potential of the applicant, including writing skills. As a formal qualification, you must hold a PhD degree (or equivalent).
