Biogeochemical reactions under fluid flow

We study biogeochemical reactions at solid-fluid interfaces under fluid flow combining microfluidics experiments with pore-scale reactive transport modeling. The pore scale investigation will elucidate key mechanisms that govern the interplay between fluid flow and biogeochemical reactions. Experimental findings at pore scale will be incorporated in pore-scale models which will provide the framework for capturing macroscopic phenomena. Two main research motivations are:

  1. Bimolecular reactive transport in rough fractures
  2. Coupling between biogeochemistry and fluid flow in extreme subsurface environments
  3. Biofouling in porous media

Figure below shows two different iron precipitation patterns caused by change in hydrodynamic conditions.
