Forschungszentrum Jülich, Germany
since Feb 2016

• Contributing to acquisition of third party funded research projects (e.g. BMBF, HGF IVF)


• Installation of a microfluidic laboratory at IEK-6 (purchase of microscope, and other laboratory equipment) and micromodel fabrication.


• Conducting experiments for assessing dissolution and precipitation of minerals in porous media that lead to fracturing, gas generation and gas transport in porous media. These experiments help to gain process understanding of coupled processes and serve as benchmarks for improving and validating conceptual models implemented in numerical reactive transport simulation codes


• Geochemical and thermodynamic modelling of processes and phases relevant for nuclear waste disposal, e.g., glass corrosion, layered double hydroxides, and radionuclide uptake in sulphate solid solutions.


• Continuum scale reactive transport modelling of evolving porous media. Imaging techniques, e.g., Magnetic Resonance Imaging (MRI) for in situ live monitoring of chemical processes in and transport properties of porous media.

Oct 2012 – Jan 2016
Ph.D. Thesis: Dissolution-Precipitation in Porous Media: Experiments and Modelling

• Development of 2D reactive transport experiments to evaluate implementations of coupled processes in reactive transport codes (e.g., density driven flow, precipitation and dissolution processes leading to porosity clogging and solid solution formation).


• Post experimental characterisation using synchrotron based micro-XRD and XRF.


• Modelling using OpenGeosys-GEM.


• Initiation of a benchmark exercise addressing chemical hydraulical couplings in collaboration with 5 renowned international research institutions.
