Andrea Bertozzi gradua<\/span>ted in Mechanical Engineering at Delft University of Technology in September 2024 with the thesis \u201cSimulation-based <\/span>optimal design of floating platforms for offshore Airborne Wind Energy systems\u201d in collaboration with MORE Lab at Politecnico di Torino. From September 2024 to April 2025 he was Junior researcher at MORE Lab. From April 2025 to November 2025 he was at Kitepower as Junior systems engineer. Since December 2025, he has been working on his PhD at SAS-Lab under the supervision of Prof. Lorenzo Fagiano. His PhD project is part of the Marie Sk\u0142odowska-Curie Action AWETRAIN<\/a>, and focuses on Fully Autonomous AWE operation over Long Time Horizons. <\/span><\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
