Geologist and prehistorian
Geologist and prehistorian by training, Jean-Jacques Bahain is a professor at the Muséum National d'Histoire Naturelle in the UMR 7194 "Histoire naturelle de l'Homme Préhistorique". He has devoted most of his career to establishing the geochronological framework of human evolution through the dating of geological and archaeological sites. A specialist in electron spin resonance dating, he uses this method, alone or in association with other methods, to specify the chronology of the first human occupations in Eurasia through the study of geological systems and deposits of regional reference, in order to better characterize and understand the successive phases of human, animal and plant settlements and migrations, and to place the archaeological sequences within the same global chronostratigraphic framework. Its research activities are based firstly on a stratigraphic field approach, fundamental in Paleolithic archaeology, and secondly on a solid laboratory experience in the field of geochronology and physico-chemical characterization of sediments and materials from Quaternary geological or archaeological deposits. This work is carried out all over the world and has been the subject of more than 200 scientific publications.
