Research
Research Interests
- Geochemistry of clay systems (bentonite, clayrocks)
- Diffusion in clay materials
- Interfaces between clays and metals (Fe, Cu, Ti)
- Reactive transport modelling in clay environments
- Contaminants in groundwaters and surface waters
My ambition is to pursue – whenever possible – a holistic approach based on the methodological triad lab–field–modelling. The conceptual methodology for studying mineral-water processes in “real” systems is sketched out in the figure below. It shows the different ingredients grouped as tools (e.g. analytical methods, mathematical codes) and data (e.g. experimental data from lab or field experiments, thermodynamic / kinetic data). Such a comprehensive approach is only possible in a skilled multidisciplinary team. I collaborate with many colleagues in Switzerland and abroad, specialised on different topics.

Most of my research has an applied focus centred on geological disposal of radioactive waste. Specific areas are:
- Geochemistry in the engineered barrier system (EBS) of high-level waste repositories
- Diffusion processes in the EBS
- Geochemistry and diffusion in argillaceous host rocks
- Steel corrosion and its impact on the bentonite barrier
- Transport of radionuclides in the EBS and host rock
- Coupled thermal-hydro-mechanical-chemical processes in the EBS
