Grazia Leonzio is a Research Associate at the Imperial College London (Chemical Engineering department). Grazia has a strong background in renewable energy, carbon dioxide, modelling and optimization of chemical processes with environmental analyses. In her PhD thesis, she developed a mathematical model for a carbon capture utilization and storage supply chain, focusing the attention on carbon dioxide utilization (particularly methanol production). Currently, she is working on direct air capture to remove carbon dioxide from the atmosphere, electrochemical processes for carbon dioxide utilization according to a digital and circular economy and supply chains modelling.
