 at Atalaya open pit (Proyecto RioTinto), Province of Huelva, Spain


I am a graduate student at the Institute of Mineralogy at TU Bergakademie Freiberg and a member of the interdisciplinary Krüger Research School, the Biohydrometallurgical Center for Strategic Elements ("BHMZ"), which is funded by the Dr.-Erich-Krüger-Foundation. In my research, I focus on the geology of indium- and germanium-bearing base metal deposits. I work with SEM-EDS (MLA), EPMA and LA-ICPMS analytical techniques, as well as fluid inclusion research of gangue and ore minerals in my PhD.
