The Helmholtz Centre Potsdam – GFZ German Research Centre for Geosciences is the national centre for geosphere research. As a member of the Helmholtz Association of German Research Centres we are part of the largest scientific organization in Germany. With approximately 1,500 employees our key mission is to secure a profound understanding of the systems and processes of solid Earth, to develop strategies and options for action in addressing global change and its impacts on a regional level, to understand natural hazards and to minimize associated risks, to ensure the sustainable provision of energy and raw materials for a high-tech society and to evaluate the influence of human activity on system Earth.
For Section 3.4 "Fluid Systems Modelling" (Department Geochemistry), we are looking for a:

PostDoc (f_m_x) - Reactive transport simulation of radionuclide migration in argillaceous formations

Reference Number 9213

Your responsibilities:

  • Conduct coupled numerical simulations to assess the potential environmental impact of high-level radioactive waste disposal in the overall hydrogeological system
  • Quantification of radionuclide migration in argillaceous formations on the host rock scale with a special focus on the geological conditions in Germany
  • Performance and evaluation of scenario analyses
  • Further development of existing, coupled modelling approaches to quantify the prevailing hydrogeochemical processes and possible process interactions
  • Presentation of own research results at national and international conferences and publication in scientific journals in English and German
  • Scientific and content-related support for ongoing research projects within the scope of the area of responsibility
  • Teaching courses at the Institute of Geosciences at the University of Potsdam and supervising students and doctoral candidates

Your qualifications:

  • Master of Science (M.Sc.) with a geoscientific focus and a doctorate (PhD) specialising in hydrogeology and/or hydrogeochemistry
  • Extensive knowledge of numerical modelling of mass transport processes and geochemical reactions of radionuclides in argillaceous formations (e.g. PHREEQC)
  • Basic programming skills (e.g. Python, R)
  • Extensive experience in the application of numerical simulation programmes in the processing of scientific questions
  • Interdisciplinary research experience in understanding and quantifying complex relationships and interactions in geological systems
  • Ability to cooperate in interdisciplinary and international working groups
  • Very good written and spoken German language skills are required, as the field of work focuses on the final disposal in Germany and the teaching takes place in the Bachelor's degree programme
  • Extensive knowledge of the German site selection procedure for the final disposal of highly radioactive waste is required

What we offer:

  • Ambitious and varied tasks in a dynamic and international research environment
  • State-of-the-art equipment
  • Public service benefits
  • Extensive training opportunities
  • Professional career advice offered by our in-house Career-Centre
  • Flexible working hours and conditions
  • Support with finding a good work-life balance offered by benefit@work
  • Institute day-care centre on site
  • Working at the Albert Einstein science park on the Telegrafenberg in Potsdam 
  • Work place within walking distance of Potsdam main train station, or just a short ride on the shuttle bus

Start date: 1st January 2025
Fixed-term: 3 years
Salary: The position is classed as salary group 13 according to “TVöD Bund (Tarifgebiet Ost)”. The salary group is determined on the basis of the Collective Wage Agreement and the respective personal qualifications.
Working hours: Full-time (currently 39 h/week); The position is generally suitable for part-time work.
Place of work: Potsdam
