I received a Doctorate (PhD) in Prehistory with Honours in 2012 from the University of Paris X, Nanterre, France. I’m currently a senior researcher in Prehistory at Centre National de recherches Préhistoriques, Anthropologiques et Historiques in Algiers (Algeria). My fieldwork concentrates in Northern Algeria with a special focus on lithic technology. I work on several aspects related to Terminal Pleistocene-Early Holocene Hunter-Gatherers settlements and brought new data on technology, subsistence and mobility related to human behaviours.
