Research Assistant - 0.75 working-time - salary grade E13 TV-L Berliner Hochschulen

under the reserve that funds are granted

Working field:

We are looking for a scientist a 3-year BMBF project (GEO:N - Geo Research for Sustainability) dealing with the sustainable operation of thermal energy storage systems in aquifers (Aquifer Thermal Energy Systems - ATES). The project is carried out in cooperation with the Helmholtz Center Potsdam (German Research Center for Geosciences) and the TU Bergakademie Freiberg.

The primary goal of the interdisciplinary research project UnClog-ATES is to gain a comprehensive understanding of the clogging and scaling processes in ATES systems and to demonstrate their effects on pollutant dynamics. This should help to ensure that ATES systems can be used efficiently and operated safely in the future.

The position is responsible for reactive solute transport modeling using data from 1D column experiments. The focus is on the dissolution and re-precipitation processes of carbonates and iron (hydr)oxides in siliciclastic aquifers, as well as on the concomitant mobilization/fixation of heavy metals. Based on the results, 2D/3D predictions on the reservoir behavior of potential ATES sites will be made.

The position holder is expected to support project management and science communication. Solicitation of external funding is welcomed and supported.

The position will be co-located with another position tasked with obtaining experimental data from column tests, and processing them for use in modeling.
