RESEARCH INTERESTS
As a postdoctoral Researcher in the Simó Lab, I contribute to the “GOOSE” project, which aims at resolving “Gaps in the Observation of Ocean Sulfur Emission and its modelling”. My research focuses on providing high resolution concentrations and cycling rates of climatically-relevant marine biogenic volatile organic compounds (BVOCs) from contrasting waters to improve the robustness and accuracy of Earth system models used to project future climate. Over the past decade, I mainly concentrated on dimethyl sulfide (DMS), a key sulfur volatile in climate regulation through its role in increasing the reflective properties of stratocumulus clouds when emitted into the atmosphere. In the past 5 years, my work has progressively expanded from DMS to a wider suite of climatically-relevant BVOCs by specialising in proton-transfer-reaction mass spectrometry (PTR-MS), a technology that allows us to measure trace volatiles with high mass- and time-resolution. In my role in the GOOSE project, I use stable isotopes to trace the total removal and gross production rates of these BVOCs. Through incubations of filtered and unfiltered waters from contrasting regions such as the North Atlantic, tropical Atlantic and Mediterranean Sea, under light and dark conditions, I can partition these cycling rates into biotic, photochemical and chemical processes.
