Function and Responsibilities:

• Develop and conduct laboratory experiments at geothermal similar conditions (high pressure and temperature), including investigations on  precipitation/dissolving and adsorption/desorption processes in aqueous solutions as well as their monitoring by several analytical methods

• Quantitative analytical studies of high salinity brines and geothermal scales (UV-VIS spectroscopy, FT-IR, ICP-OES, GC, MS and wet chemical analysis).

• Development of new sustainable adsorption methods and adsorbents for use in geothermal conditions

• Monitoring geochemical parameters at geothermal sites at in-situ conditions across Europe (Germany, Netherlands, Denmark)

• Solid phase characterization of precipitates from geothermal sites

• Work in an interdisciplinary team with postdocs, and staff both, at GFZ and within the partners of the EU project

• Laboratory management of the Working Group 4.8.4 Geothermal fluids

• Supervision of bachelor and graduate Students

Research Interests:

Understanding physicochemical processes in geothermal fluid systems.

Development of new methods to prevent undesirable chemical processes in the geothermal cycle.

Development of new selective adsorption materials and methods for non-invasive raw material extraction from geothermal fluids in addition to heat extraction.

Projects:

CRM-Geothermal (EU) - Developing an innovative technology solution which combines the extraction of critical raw materials and energy from geothermal fluids to decrease the European Union’s dependency on imported resources, supporting the EU Green Deal.
