Research Scientist (PostDoc) on Experimental Fracture Mechanics (m/f/x)

Helmholtz Centre Potsdam - German Research Centre for Geosciences (GFZ)

Potsdam, Germany

Area of research:

Scientific / postdoctoral posts



Job description:

The Helmholtz Centre Potsdam – GFZ German Research Centre for Geosciences is the national research centre for Earth sciences in Germany. With approximately 1.280 employees (including visiting scientists), the GFZ is conducting interdisciplinary research on the “System Earth” and the influence of humans on the planet. As a member of the Helmholtz Association, it is part of Germany’s largest science organization. For the recently established Helmholtz Young Investigator Group “Advanced reservoir engineering concepts for a controlled utilization of deep geothermal energy in urban areas (ARES)” in Section 4.8 "Geoenergy" we invite applications for a

Job Vacancy No. 3991


The research group develops concepts and workflows for enhancing the hydraulic performance of deep geothermal reservoirs while minimizing environmental impacts such as induced seismicity. Research methods include experiments at laboratory, mine and field scale as well as numerical modelling studies. We pursue our research in tight interdisciplinary collaboration across scales and across disciplines together with national and international partners.The research scientist will be responsible for planning and performing proof-of-concept studies at laboratory scale. This involves quantification of the hydraulic, mechanical and seismic response of intact and fractured rock samples to different fluid injection schemes and operational constraints. Emphasize will be given to differentiate between the effects of individual engineering parameters and geological boundary conditions. The results will improve the understanding of proposed geothermal reservoir engineering concepts and influence the design of mine and field scale experiments.

Your responsibilities:

  • improve existing laboratory setups and establish a workflow for fluid-injection experiments including sample preparation, hydraulic, mechanical, and seismic monitoring during the experiments and sample inspection after the experiments
  • plan, perform and analyse laboratory experiments that allow a systematic evaluation of the influence of operational parameters and geological boundary conditions on hydraulic performance and fluid-injection induced seismicity
  • assist in integrating the laboratory results with mine and field scale results as well as numerical modelling studies
  • collaborate closely with internal and external national and international partners
  • publish in international peer-reviewed journals and present results at scientific meetings
  • lead and contribute to writing research proposals
  • co-supervise PhD and MSc students who perform and/or analyse laboratory experiments
  • the iopportunity to assist in teaching will be given

Your qualifications:

  • Master’s degree (or equivalent) and PhD degree in geosciences, geophysics, engineering or equivalent with a strong focus on fracture mechanics and/or seismology; background in geothermal energy is an asset
  • at least 3 years of well-documented hands-on experience in rock deformation experiments, fluid injection experiments and acoustic emission monitoring; experience with fibre optics is an asset
  • skills in development of data processing tools and unique experimental setups
  • willingness and ability to work in multiple projects simultaneously in interdisciplinary and international teams
  • excellent communication skills
  • proficiency in spoken and written English; German is an asset
