Profile

Postdoc in the geo-engineering section

Research interest

In situ remediation and engineering techniques, colloid/nanoparticle transport in porous media, metal – organic matter interactions

Current project

SoSeal – Soil Sealing by enhanced aluminium and organic matter leaching

Within the SoSeal project we aim to develop a bio-based geo-engineering technology for in-situ permeability reduction that will be applied to reduce the infiltration loss or the seepage burden due the unwanted flow of water through highly permeable layers in the subsurface. Naturally occurring processes involving the precipitation of organic matter and aluminum reduce the permeability. We aim to utilize the great potential of these natural processes for engineering purposes.
