Deciding to pursue a M.S., he then joined the double degree program between Sapienza and Georgia Tech. In 2023 he graduated at Georgia Tech presenting his work on quantitative models for hydrogel swelling equilibrium. Matteo is currently a PhD student in Materials Science and Engineering at Georgia Tech. Co-advised by Dr. Natalie Stingelin, he investigates possible new methods to enhance chemically upcycling of multilayer plastics, focusing on adhesive dissolution at buried interfaces.
