Biogeochemical modeller @ NOC, UK
Funding: ERC, UKRI-NERC
I'm currently involved in a variety of projects at NOC Southampton.
GOCART and COMICS: Study of oxygen and particle variability in the mesopelagic of the northern Benguela Upwelling System via the analysis of in-situ data from gliders and ship, satellite data, model reanalysis and a new coupled model setup for the Benguela that I developed at NOC (see also previous project below).
SUMMER: Quantification of the export of DOC and POC via diapycnal mixing and comparison with active and sinking fluxes using ship data from South Georgia.
PAP-SO: Fieldwork and data analysis for the PAP Sustained Observatory.
TechOceanS: Scientific input for the planning of autonomous surveys at Gran Canaria.
Group: Marine Biogeochemistry, within the Ocean BioGeosciences (OBG) group of NOC

The influence of mesoscale variability on organic carbon export fluxes: bridging models and observations
2020-2021, Visiting Postdoc fellow @ NOCS, UK
Funding: SNSF Early Postdoc.Mobility
The goal of my project was to study how mesoscale structures influence the export of organic material and oxygen concentrations in the Benguela Upwelling System. The study was developed by combining the use of glider data (GOCART project), ship data (COMICS project), satellite products, ocean reanalysis data and a high resolution coupled physical-biogeochemical ocean model (ROMS + BEC).

Exploring the impact of changes in the biological pump on the shelf sea and ocean nutrient and redox state
2019, Postdoc fellow @ University of Exeter, UK
Funding: NERC
Implementation of a Biological Pump, Oxygen and Phosphorus (BPOP) model accounting for two organic matter species generated by production and coagulation and aimed at studying changes in the ocean biogeochemistry generated by the evolution of larger and heavier phytoplankton cells at the Neoproterozoic-Phanerozoic transition (language: Matlab).
