Geochemistry

The challenges of global warming and energy security are the drive behind our research. We develop new methods and geomaterials, and help members learn new skills that are vital in a sustainable future.

We lead multidisciplinary research linking chemistry to earth science and engineering. We synthesize and characterize heterogeneous geomaterials which underpin the development of geoenergy, underground gas storage, and water treatment. We investigate fluid-rock physicochemical processes (coupled geochemistry-geomechanics) to identify and mitigate environmental risks.

Key interests and expertise

Our scientific vision is to adress the challenge of complexity and heterogeneity of rocks and fluids in controlling the mechanistic pathways and kinetics of chemical reactions and reactive transport.

The application and context of our research focuses mainly on underground gas storage, and water contamination and treatment. We have also abundant expertise in diagenesis, fluid-rock physicochemical processes, in particular in carbonate rocks.

We take a multidisciplinary approach, and have expertise with geological field work, remote sensing, microscopy (polarization microscopy, cathodoluminescence microscopy, scanning electron microscopy), fluid inclusion geothermometry, X-ray diffraction analysis, chemical analysis (inductively coupled plasma atomic emission spectrometry and mass spectrometry, X-ray fluorescence spectrometry), isotopic analysis (carbon, oxygen, sulphur, strontium, and clumped isotopes), structural analysis (fractures), geomechanical analysis (uniaxial, triaxial), batch reactor, column and flow reactor experiments (rock and mineral dissolution kinetics, heavy metal leaching, contaminant adsorption), 3D imaging (computed tomography).

Current projects

  • Modeling membrane efficiency in desalination
  • Acidic fluid flow in heterogeneous porous media
  • Water treatment in Egypt
  • Fluid-rock interaction in geothermal systems
  • Environmental risks of gas storage in salt rocks
  • Mobilization of elements during shale-water contact
