My MA thesis was devoted to techno-typological analysis of Lower Palaeolithic tools. Now I am a PhD student in Tel Aviv University, and my work is focused on deciphering the function of this tools by use-wear analysis, or in other words, by looking for traces that were left on the lithic tools as a result of their use. Experiments are an important and integral part of this study. To understand the traces, I had to replicate the same tools and use them in different tasks and with different materials to be able to compare the resulting use-wear signs with the real archaeological artifacts. The activities that I'm experienced with are butchering, hide processing, bone, wood and plants working.
