Phd Researcher (F/M/X): Studying The Metabolic Interaction Within A Microbiome Model System, Focusing On The Role Of Transporters

The Job

In the Department of Molecular Toxicology in Leipzig, we invite applications for a PhD Position (f/m/x) to study the metabolic interaction within a microbiome model system, focusing on the role of transporters by cultivation and multi-omics approaches. The project is funded within the DFG Priority Program 2474 on Novel Functions within the Microbiome. It will be conducted in close cooperation with our partner C. Kaleta in Kiel, who is an expert in metabolic modelling.

Your Tasks

• You will cultivate the simplified human gut microbiome model (SIHUMIx) in a continuous culture and analyse the species-specific secretion and uptake of metabolites by mass-spectrometry-based metabolomics.
• You will detect the presence of transporters and metabolic enzymes by mass-spectrometry-based metaproteomics and meta-transcriptomics, and integrate multi-omics information to detect associations between metabolism and transporter abundance.
• You will develop mutants and CRISPR/Cas approaches to validate the interdependency of metabolic pathways and transporters in the SIHUMIx consortium.
• You will cooperate with our partner in the project to validate genome-based metabolic models. You present results at international conferences and prepare publications in peer-reviewed scientific journals.
• You present results at international conferences and prepare publications in peer-reviewed scientific journals.

We Offer

• Excellent supervision and optimal professional and interdisciplinary qualification through our HIGRADE graduate programme
• The freedom to master even the most demanding challenges between basic research and practical application
• The opportunity to work in interdisciplinary, international teams and benefit from a wide range of perspectives
• Firstclass integration into national and international research networks to work together on global challenges
• Excellent research infrastructure and research data management to optimally support your work
• A wide range of options for balancing care responsibilities and work through our family office
• Competent support and advice for international colleagues arriving at the UFZ from the ‘International Office’
• Special annual payment, capital-forming benefits and subsidised Deutschland-Job-Ticket
• A workplace in a vibrant region with a high life quality and social and cultural diversity

Your Profile

• Master's, Diploma or equivalent degree in biological or biochemistry, or related areas
• Experience in analytical chemistry
• Skills in bioinformatics with a focus on statistical tools for analysing omics data
• Motivation to work in an interdisciplinary team or similar
• Proficiency in scientific English (written and spoken)
