PhD position - industrial biotechnology / bioeconomy

Jülich Research Centre (FZJ)

Jülich, Germany

Work group:

IBG-1 – Biotechnologie



Area of research:

PHD Thesis



Job description:

The IBG-1 „Systems Biotechnology“ is working on the development of bioprocesses based on a systems biology fundament. Both whole cell and cell free approaches are pursued. As central tools, quantitative bioanalytic methods (metabolomics, fluxomics, proteomics) and mathematical models are developed both for a detailed characterization of the complex biochemical networks inside a living cell and for the investigation of whole bioprocesses. These projects are complemented by the development of microfluidic devices for single cell analysis for which newly developed biosensors are applied.


Your Job:


The project aims at developing potential biorefinery processes for selected organic acids based on two engineered model organisms. Your work will focus on the characterization of existing producer strains toward their conversion efficiency for different industrially relevant feedstocks (including waste streams such as molasses, crude glycerol and black liquor). You will work closely together with colleagues from metabolic engineering as well as down-stream processing and the performance data obtained from your cultivation experiments will directly support further strain and process optimization.Your tasks in detail:



  • Comparative characterization of engineered Ustilago and Corynebacterium strains using our Mini Pilot Plant technology

  • Laboratory evolution experiments to improve growth on the most relevant feedstocks

  • Support of further rational strain optimization based on the newly generated knowledge

  • Optimization and scale-up of selected production processes in lab-scale bioreactors

  • Participation in conferences in Germany and abroad (incl. presenting your research results)

  • Exchange with internal and external project partners

  • Preparing scientific publications and project reports

  • Mentoring students

Your Profile:

  • MSc degree in Biotechnology, Bioengineering, Chemistry, Biochemistry or comparable disciplines, with an overall grade of at least “gut” (or equivalent, e.g. cum laude)
  • Expertise in microbial cultivation technology and bioprocess development
  • Basic knowledge on metabolism of prokaryotic and eukaryotic organisms
  • Experience in mathematical modelling is an advantage
  • Fluent command of written and spoken English
  • High degree of independence and commitment
  • Very reliable and conscientious style of working
  • Excellent ability to cooperate and work in a team

Our Offer:

  • Outstanding scientific and technical infrastructure – ideal conditions for successfully completing a doctoral degree
  • A highly motivated group as well as an international and interdisciplinary working environment at one of Europe’s largest research establishments
  • Chance of participating in (international) conferences and project meetings
  • Continuous scientific mentoring by your scientific advisor
  • Doctoral degree conferred by RWTH Aachen University
  • Further development of your personal strengths, e.g. via a comprehensive further training programme
  • Above average pay equivalent to 75 % of pay group 13 of the Collective Agreement for the Public Service (TVöD EG 13)
