Research areas
- Numerical modeling of reactive transport in soil and groundwater
- Remediation strategies for regionally contaminated aquifers (including Natural Attenuation, Enhanced Natural Attenuation, Gas Sparging, Constructed Wetlands)
- Application of non-invasive imaging methods to study dynamic processes in porous media
- Urban hydrogeology (including soil-plant-groundwater interactions)
- Variable density flow in porous media
- Integrated water- and soil management
Key working areas
- 2-D and 3-D imaging of flow & transport, biodegradation and plant uptake mechanisms via Magnetic Resonance Imaging (NMR), Neutron Radiography (NR) and Fluorescence Imaging
- Simulations of biogeochemical reactions in the subsurface including degradation of organic chemicals and the transfer of heavy metals
- Kinetic mass exchange at interfaces and gradients, e.g. at the surface of trapped gas bubbles, reactions fronts and permeability contrasts
- Improvement of remediation and land use strategies
Current own research projects
