I am a member of X-ray tomography team in NanoGeoScience group. My project is to study the surface and bulk characterization of chalk. I use X-ray reflectivity to investigate the interactions of organic compounds with the calcite surface, and X-ray micro-tomography to study the porous morphology of chalk in rock-water- CO2 system.
