My research focuses on data analysis of in situ observations of physical and carbon system variables, with the aim of better understanding ocean's role in climate as a carbon pump.

I am specifically interested in the study of the linkages between ocean dynamics and the biogeochemical (carbon, oxygen and nutrient) cycles, their spatiotemporal variability, and the underlying processes driving such variability. My current focus is on the North Atlantic, a key oceanic region for the storage of anthropogenic carbon. I aim to contribute to new and existing hydrographic databases (e.g. GO-SHIP, mooring-based, Argo) with novel observations that help improving model representation of the biogeochemical processes and future climate predictions.
