Currently, he is working as a PhD Researcher at Universität Autònoma de Barcelona. Gian’s PhD project at ICTA-UAB was developed within the MERS group under the supervision of Professors Patrizia Ziveri and Michaël Grelaud. The PhD project aims to analyze the interaction of chemicals and heavy metals with plastic membranes. The modification of the plastic surface by microorganisms provides a suitable charging condition for the adsorption of metal ions. Starting from the results of preliminary studies showing greater adsorption of chemicals on bioplastic films, the project will analyze the role of micro-fragments of bioplastic films as carriers in terrestrial and aquatic environments. The description of the adsorption phenomenon and the physicochemical degradation process of the membranes will be analyzed to study soil and water pollution phenomena.
