PhD Project

 

My PhD project was about in-situ, high resolution, study of porosity in clay rich geo-materials by BIB-Cryo-SEM techniques. In December 2014, I defended my PhD thesis called: "Pore space characterization of organic-rich shales using BIB-SEM". Currently I am setting up a spin-off, EXIST Nanoporosity, with my colleagues on the application of (cyro) Broad Ion Beam (BIB) polishing and SEM imaging on fine-grained rocks, reservoir rocks and metal injected mudstones. We are funded by the Exist Forschungs Transfer programm of the BMWi (Bundesministerium für Wirtschaft und Energie).
