Above all: tackle the global carbon budget by quantifying complex processes controlling the carbon cycle in aquatic systems.

“The interface must be the place”: air-water and sediment-water solutes exchange dynamics.

Practically: development and application of novel approaches coupling biogeochemical analyses to physical models.
