Research

I have a very wide scientific interest; it may perhaps be problematic for my efficiency: so be it.

• from inorganic geochemistry via biogeochemistry to ecology

• from elemental-cycles oriented to organisms-oriented studies

• from weathering of rocks to deep-sea pore-waters

• from laboratory studies and field observations to numerical modeling

• from global scale down to nanometer scale, including use of NanoSIMS@Utrecht

• and through the use of reductionistic as well as holistic and explorative approaches.
