I work at Laboratoire de glaciologie et géophysique de l’environnement on the reconstruction of past climates and climatic forcings using "archived" physico-chemical markers in sediments, mainly ice. These markers are natural isotopes, whose chemical behaviour, or isotopic fractionation due to their mass difference, is sensitive to climatic conditions ('isotope thermometer'), or to solar forcing (cosmogenic isotope production). Now part of the Institut des géosciences de l’environnement.
