Research interests

I am interested in the relationship between coccolithophores (haptophytes secreting calcium carbonate plates around their cell) and their environment, notably through paleoceanographic/paleoclimatic reconstructions. I thus use a multi-proxy / multi-disciplinary approach (micropaleontology, organic geochemistry, sedimentology, biostratigraphy, etc.) in Mesozoic and Cenozoic marine sediments. My studies aim to quantify nannofossil assemblages in order to better characterize the ecological preferences of these algae during the past and to understand the global evolutionary patterns that can be linked to environmental changes. In parallel, I use lipid biomarkers as paleoceanographic proxies. Lipid biomarkers can be used as indicators of the presence of an organism and metabolic processes (primary production), but they may also be used as proxies for environmental parameters (temperature, pH, pCO2, etc.).

In addition, I intend to better constrain the use of alkenones as paleoenvironmental proxies. My PhD work aimed to identify the marine coccolithophore species responsible for the production of alkenones during the Cenozoic, in order to better constrain the use of these long-chain unsaturated ketones in sea-surface temperature and pCO2 reconstructions. I am now studying alkenone composition and alkenone producers in Canadian lakes in order to develop a temperature calibration for paleoclimate reconstructions in continental settings.
