-> Management of the work stream for validating the decarbonisation pathways of industry. Main tasks: coordinating the work of multiple modelling teams, defining new narratives for industry tranformation to meet climate targets. -> Assessment of the decarbonisation potential and techno-economic feasibility of transformative technologies for industry. Main tasks: estimation of marginal abatement costs, levelized cost of energy (LCOE), emissions accounting, analysis of energy demands.

-> Management of a multidisciplinary research team and coordination of the experimental work for the optimisation of a chemical process for capturing exhaust CO2. -> Main achievements: maximised sustainability and market potential of the process by reducing the reactants consumed (- 90%) and recovering by-products with high commercial value (silica). Enhanced CO2 capture implementation with a chemical reaction conducted under ambient temperature and pressure.
