Pierre Sabatier is a lecturer in geology at the Université Savoie Mont Blanc assigned to the laboratoire EDYTEM (Environnement DYnamique et TErritoire de Montagne). He is working to reconstruct the past climate and environment from sediment cores collected mainly from lakes. In order to understand past variations, he uses sedimentological, geochemical and geochronological methods. He is responsible for the laboratory's « Archives environnementales » team and has published more than 30 scientific articles on climate and past environments in peer-reviewed journals. Between 2012 and 2015 he was a member of the CNRS national committee in section 19 « Système Terre : enveloppe superficielle ».
