The Novo Nordisk Foundation Center for Biosustainability (DTU Biosustain) is seeking a highly motivated researcher with an interest in computational approaches to microbial systems biology for the purposes of strain design. We are looking to fill one PhD position in the newly established C1 Metabolism group, headed by Prof. Lars Keld Nielsen and A/Prof Nikolaus Sonnenschein.

In order to realise emission reduction targets, we need to completely replace our current reliance on fossil fuels for the production of food, fibre and transportation fuel with a sustainable alternative. Plant biomass production is associated with its own challenges concerning water and land use and the disruption of the nitrogen and phosphate cycles with associated eutrophication. This challenge can be addressed by moving production to closed systems using photoautotrophic or chemoautotrophic microbes. A vast range of natural photo- and chemoautotrophic metabolisms is currently being explored. In addition, new C1 metabolisms are being invented and implemented in common fermentation microbes, such as CO2 and formate assimilation in E. coli. No system has emerged as inherently better than others, and all systems have significant shortcomings. Moreover, many of the relevant organisms are poorly characterized.

Our group’s initial focus is to develop a Global C1 Metabolic Atlas in close collaboration with leading researchers and companies working on C1 metabolism in organisms such as acetogens, methanotrophs, and cyanobacteria. Your project will be focused on reconstructing C1 metabolism of Clostridium autoethanogenum.

Responsibilities and qualifications
Based on a large multi-omics dataset encompassing gene deletions in C. autoethanogenum, constructed in a collaboration with Joint Genome Institute (JGI), University of Queensland, University of Tartu and the company Lanzatech, you will mine the data for gene functions, transcription factors and global regulatory patterns.

Specific tasks include:

  • Reconstructing of strain and species-specific metabolic networks of from genome annotations and experimental literature to enable metabolic modeling applications.
  • Pangenome analysis of solventogenic clostridia to identify new pathways.
  • Annotating protein structure and genome sequence information for the analysis of sequence variation.
  • Transcription regulatory analysis of organism gene and protein expression data
  • Contribution to development and implementation of computational methods and tools described above.
  • Participation in a team environment as part of a large academic organization developing computational tools and workflows for strain design.
  • Organization of (bi-)weekly project updates to lab management.

We are looking for a colleague with previous experience working with metabolic network reconstructions, with substantial knowledge of metabolic biochemistry. This includes familiarity with methods for computational modelling of metabolism, including constraint-based and kinetic modelling, and an understanding of the relevant methods such as linear programming and matrix decomposition.

Most of our programming is in Python/Pandas and intermediate level programming skills are essential. Experience interfacing databases and R scripting will be an advantage but not required.

Additionally, your CV will demonstrate ability to:

  • communicate technical information to internal/external audiences at various levels (undergraduates to senior scientists) and from various backgrounds (technical and non-technical personnel);
  • work independently and as part of a team; and
  • successfully work on multiple concurrent projects and meet deadlines.

You must have a two-year master's degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master's degree.

Approval and Enrolment
The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes at DTU. For information about our enrolment requirements and the general planning of the PhD study programme, please see the DTU PhD Guide.
