Postdoctoral Research Associate in Seismology/Geophyiscs
Gutenberg University Mainz
Johannes Gutenberg University Mainz (JGU) is one of the largest universities in Germany. Thanks to its location in the Rhine-Main science region, the university can unfold to its full potential and showcase its innovative power and dynamism. Its status as a comprehensive university allows for multidisciplinary learning and teaching and has great potential for internationally renowned, interdisciplinary research. Almost all of its
institutes are located on a single campus close to the Mainz city center – creating a lively academic culture for researchers, teaching staff, and students from every continent.

Seismology (SM)
We are looking for a candidate as part of the TRIGGER project (Formation of fractures and changes in permeability in geothermal reservoirs caused by thermally induced stress changes) funded by the Federal Ministry of Economics and Climate (BMWK) to work on the evaluation and interpretation of acoustic emissions from laboratory tests. The aim of the project is to understand the longterm effects of temperature changes in
geothermal reservoirs. To this end, laboratory tests on drill cores, comprehensive microstructural and microchemical analyses and modelling will be carried out to determine a temperature change of at least 100 K on crack formation and fluid-rock interactions (dissolution/precipitation) and thus on rock mechanical properties, porosity and permeability on the sample scale. The candidate will participate in deformation experiments carried out at the Ruhr University Bochum (RUB). Acoustic emissions will be recorded, which will provide information about the fracture processes on a sample scale, similar to seismic recordings of earthquakes on a field scale. The role includes the development of novel tools to analyse the fracture processes as well as tomographic imaging of the drill cores.
