PhD Position (f_m_x) - Uncertainty analysis of coupled transport models for radionuclide migration

Reference Number 10036


The handling of highly radioactive waste is one of the most pressing issues in our modern society. Worldwide, disposal in deep geological formations, for example in claystone, is regarded as the safest option. Migration of radionuclides in argillaceous formations is governed by diffusion and sorption and depends on the geochemical and mineralogical conditions. Quantifying both processes with coupled transport models therefore requires many parameters, all associated with uncertainties. The focus of the PhD is on analysing and evaluating the uncertainties associated with reactive transport simulations. We are therefore looking for a person with affinity for modelling, programming and statistics, preferably with a strong background in geosciences.

Your responsibilities:

  • Geochemical and coupled reactive transport models to quantify diffusion and sorption of radionuclides in argillaceous formations as potential host rocks for the disposal of highly radioactive wastes
  • Further development of existing process models and methods for the statistical evaluation of local and global sensitivity analyses
  • Estimation of uncertainties and their propagation in geochemically complex natural systems
  • Conducting and evaluating scenario analyses
  • 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
  • Organising of lectures at the Institute of Geosciences within the framework of the PhD regulations of the University of Potsdam


Your qualifications:

  • Master of Science (or equivalent) with a natural scientific focus and specialisation in, for example, hydrogeology, hydrogeochemistry and/or geophysics
  • Programming skills are required (e.g. R, Python, C/C++)
  • Profound knowledge in mass transport modelling, statistics, data science and/or machine learning is an advantage
  • Strong affinity for the application of numerical simulation programs in the processing of scientific questions
  • Ability to work cooperatively in interdisciplinary and international working groups
  • Good written and spoken German language skills are required, as the field of work focuses on final disposal in Germany
  • Experience or knowledge of the German site selection procedure for final disposal of highly radioactive waste is desirable


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
  • 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: As soon as possible

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: Part-time 75% (currently 29.25 h/week)

Place of work: Potsdam
