<\/figure>\n<\/div>\n\n\nMy research interests revolve around marine and aquatic environments dynamics. I use a combination of measurement platforms (as moorings, satellite, gliders) and modelling approaches to study physical and biogeochemical processes regulating water, nutrients, and organic matter dynamics. The objective of my current work is to combine a mechanistic hydrodynamic-biogeochemical model (SIMSTRAT-AED2) with machine learning methods (LSTM-RNN) to predict the surface CO2 dynamics in the Lake Leman. Accurate predictions of CO2 dynamics in lakes are crucial to understand whole-ecosystem C budgets, as well as to figure out the main drivers of CO2 and the impact of their future evolution. To this end, a long-term observations dataset (1980-2020) is used to validate the different modelling approaches. This post-doctoral position is part of the SNF-funded project CARBOGEN.<\/p>\n\n\n\n
