Research interests
My main research interest is in the use of calcareous nannofossils (coccolithophores) and lipid biomarkers in palaeoclimatic/palaeoceanographic reconstructions. This multi-proxy/multi-disciplinary approach (micropalaeontology, organic geochemistry, sedimentology, etc.) is a major component of my research. This approach is indeed very powerful to better understand palaeoceanographic changes such as the ones occurring during the Eocene/Oligocene transition or during the early Jurassic (Sinemurian/Pliensbachian).
In my research, I am also interested in the identification of the coccolithophore species responsible for the alkenone production in pre-Quaternary sediments. The identification of alkenone producers (along with the determination of their cell size) is indeed essential to obtain more accurate plaeo-pCO2 estimates, and thus better palaeoclimatic reconstructions.
