Broadly speaking, I am a paleoceanographer. My main research tool is a group of microfossils called foraminifera, which are eukaryotic, unicellular organisms. Among foraminifera, calcareous species are particularly important because the investigation of their shell chemistry provides a wealth of information about oceanic environments and climate in the geological past. In my research, I aim to better understand the connections between the environment and the foraminiferal chemical and isotopic composition to address questions related to past changes in ocean circulation, climate, and sedimentary biogeochemical cycles.
Even if most of my research time is spent between a laboratory and an analytical facility, fieldwork is an important component of my research effort. For example I participated to two expeditions in different geographic locations (i.e. Svalbard and the US Atlantic margin). Also, I will be participating to the International Ocean Discovery Program Expedition 390, scheduled for April-June 2022.
