PostDoc Researcher, ERC DiverseNile Project
Fabian.Dellefant@lmu.de
Fabian Dellefant completed a PhD at the Department of Earth and Environmental Sciences at the Ludwigs-Maximilians-Universität Munich focusing on shock effects of Fe-Ti-oxides generated by meteorite impacts, which can contribute to km-scale magnetic anomalies. In his work, the application of Raman spectroscopy plays a central role, which he now utilizes to investigate maximum firing temperatures of archaeological ceramic samples in the framework of the DiverseNile project. Fabian possesses extensive experience in characterizing materials from various perspectives, including (magneto-)mineralogy, crystallography, and geology. He intends to leverage this expertise in investigating the petrography and potential provenance of Egyptian sandstone building materials.
