Sujets de recherche

Je travaille dans l'équipe PALEOCEAN du LSCE dont les thématiques scientifiques s’articulent autour de la compréhension des mécanismes de la variabilité climatique passée. Ces études reposent sur l’utilisation de traceurs géochimiques à partir de coquilles carbonatées prélevées dans les milieux naturels (dont sédiments marins).

My principal research interests lie in the fields of paleoclimate, paleoceanography and geochemistry. I am particularly interested in foraminiferal chemical and isotopic record from marine archive to study past oceans and climates over time scales of centuries to hundreds of thousands of years. The goal of this research is to elucidate the mechanisms for global climate change on both millennial and orbital time scales. In my group, I am mainly in charge of the Mg/Ca ratio determination and isotopic composition of forams, which are used to determine paleotemperature and paleosalinity of ocean waters.
