I am a postdoctoral researcher in the research group Quaternary Archaeology at the Department of Prehistory & West Asian/Northeast African Archaeology of the Austrian Archaeological Institute of the Austrian Academy of Sciences. Since my master’s, I focus on lithic technological developments in the southern African Stone Age. In 2019, I finished my PhD on the C-A layers of Sibhudu Cave (KwaZulu-Natal, South Africa) in the light of the MSA lithic technologies in MIS 5 with “magna cum laude” in a joint doctoral programme at the Universities of Tübingen and Paris Nanterre. I started my Hertha Firnberg project ‘Time of essential changes in human history (TECH)’ in October 2022. The project concerns the analysis of lithic assemblages from three quasi-synchronous sites, Sibhudu Cave, Bushman Rock Shelter, and Rose Cottage Cave, in different biomes of South Africa. My aim is to gain a better understanding of the lithic technology, innovativeness and connectedness of past societies in South Africa during Marine Isotope Stage 5.
