Stephan Naji is a bioarchaeologist with a dual training in archaeology (MA, University of Paris 1) and biological anthropology (MS, University of New Mexico). His interests in contextual analysis of human remains and paleodemography merged with his doctorate in Archaeology from the École des Hautes Etudes en Sciences Sociales in 2010. He is specialized in field funerary archaeology (archaeothanatology) and demographic transitions of past populations. He has directed several bioarchaeology field schools in Peru, Italy and France. Since 2010 he has been building a network of international researchers focused on cementum analyses (cementochronology). The purpose of this interdisciplinary group is to develop robust protocols for faunal and human remains in order to assess age-at-death and seasonality of death. To achieve this goal, as part of a postdoctoral position at the CEPAM (University of Nice, CNRS), he is now coordinating at CIRHUS within the ANR CemeNTAA (L. Gourichon and W. Rendu, P.I.), a team of leading experts in advanced imaging technologies to explore and understand acellular cementum ultrastructure.
