Karlsruhe Institute of Technology (KIT) – The Research University in the Helmholtz Association creates and imparts knowledge for the society and the environment. It is our goal to make significant contributions to mastering the global challenges of mankind in the fields of energy, mobility, and information. For this, more than 9.000 employees of KIT cooperate in a broad range of disciplines in research, academic education, and innovation.

We are looking for the Institute of Applied Geosciences (AGW) as soon as possible and limited for 3 years for a

PhD Candidate / Research Assistant (f/m/d)

Heat transport in groundwater: The collaborative project is fully funded by the German Research Foundation (DFG). The work is supported by experienced, international experts from the Commonwealth Scientific and Industrial Research Organisation (CSIRO) in Brisbane (Australia), Utrecht University (Netherlands) and the Forschungszentrum Jülich (Germany). It will be carried out in close cooperation with the Martin-Luther-Universität Halle-Wittenberg (MLU), which have a complementary focus on field-scale processes. The candidate of our subproject is dedicated to laboratory scale analysis of transient heat flow mechanisms in different porous media using well-controlled laboratory column experiments. The insight gained through these experiments will be complemented by numerical analyses to validate the concerted role of advection, conduction and dispersion in the presence of heterogeneities. Tight cooperation with the MLU will give the opportunity to develop a consistent view of micro- and macro-scale heat transport effects caused by heterogeneity.


  • To design, plan and carry out repeated laboratory column experiments with different grain sizes and flows
  • To reproduce the transport conditions in detailed numerical models
  • To review existing literature and datasets of experiments conducted by partners and colleagues
  • To assess the individual role of advection, conduction and mechanical dispersion in the presence of different grain sizes and mixtures
  • To co-develop a consistent mathematical formulation over multiple scales

The candidate will conduct the research tasks under joint supervision of hydrogeologists and engineers. The work will be carried out mainly in Karlsruhe, with research stays at MLU as well as visits to CSIRO Brisbane (Australia). It will be based on a well-planned set of complementary activities combining laboratory work, computer-based analysis and interpretation. The participating research groups offer ideal working conditions with modern equipment and support by technicians and student assistants. The new findings will be published together in international journals and shared with the community by presentations during international conferences.

Personal qualification

  • Master or equivalent degree in a project-related field (e.g., hydrogeology, geosciences, physics, environmental engineering, mathematics)
  • Very good knowledge in experimental design, monitoring and laboratory data interpretation
  • Great interest in theoretical aspects of heat transport processes
  • Very good quantitative and computer-based numerical skills
  • Fluent in English communication in writing and speaking; knowledge of German language is an advantage
  • A clear drive to do science
  • Well organized, hands-on mentality
  • Driver’s license

We offer you an attractive and modern workplace with access to the excellent equipment of the KIT, a varied work, a wide range of training opportunities, flexible working time models, an allowance for the job ticket BW and a casino/cafeteria.

We prefer to balance the number of employees (f/m/d). Therefore, we kindly ask female applicants to apply for this job.

Recognized severely disabled persons will be preferred if they are equally qualified.
