Scientific interests:
- Water-rock interactions and their significance for the environment
- geochemical processes in geothermal systems (reactions at elevated p-, T- conditions)
- mobility of inorganic pollutants (e.g. aquatic complexes of arsenic and uranium)
- acid mine drainage and iron minerals
- following a multidisciplinary approach by considering geochemistry, geology mineralogy and microbiology
