Biography
My research topic is Biogrout. Biogrout is a soil improvement process which utilizes microbially induced carbonate precipitation (MICP). For this process substrates are added to a sandy soil where indigenous micro-organisms convert the substrate to products among which, carbonate. Together with calcium ions the carbonate then precipitates to salt crystals. Because of the presence of salt crystals the sand grains can move less easily, making the ground more sturdy. This process can be applied for example for borehole stabilization, liquefaction prevention, levee fortification and mitigation of beach erosion.
