Stephan Naji is a bioarchaeologist specializing in paleodemography, particularly in demographic and health transitions. His current research focuses on optimizing cementochronology within the broader evolutionary context of chronobiology for histological and virtual age-at-death estimation. He also actively promotes life-history events identification and modeling in cementum through interdisciplinary collaborations. William Rendu is a zooarchaeologist interested in the mobility of past human societies. He implemented cementochronology during his Ph.D. to discuss the seasonal distribution of Neanderthal activities. He is now continuing this work with a larger chronological framework as director of the International Research Laboratory ZooSCAn in Siberia. Lionel Gourichon is a zooarchaeologist. His research interest lies in the emergence of food production in Southwest Asia and the Mediterranean area, in particular on human-animal relationships and the process of domestication. He actively contributes to methodological advances in bioarchaeology to improve the study of mammal and bird remains.
