The National PhD in Artificial Intelligence (PhD-AI.it) concerns a central theme for digital transformation of society. It aims to mobilize the national community for a PhD in AI at the highest scientific level, such as to boost research and the country's industrial and social innovation. The PhD-AI.it is implemented, with the coordination of the CNR and the University of Pisa, with the establishment of 5 federated AI doctorates, organized by a university leader and a large consortium of universities and research institutions. Doctorates have a common base focused on the foundational aspects of AI e 5 areas of specialization: • Security and cybersecurity, Sapienza University of Rome • Health and life sciences, University Campus Bio-Medico of Rome • Agrifood and environment, University of Naples Federico II • Industry 4.0, Turin Polytechnic • Society, University of Pisa. Specific objectives of the PhD-AI are: • Build a community of young researchers in training and AI researchers distributed at a territorial and disciplinary level; • Encourage the exchange of multi-disciplinary experiences between the nodes of the network through the periods of didactic and research mobility of the PhD students; • Integrate and strengthen the Italian network of AI research centers, also in relation to the European ICT-48-H2020 program "Towards a vibrant European network of AI excellence centers ”and the European human- centered and trustworthy AI development strategy. Training activity Linguistics: Students of the PhD program must have an adequate linguistic preparation regarding the technical, written and oral English language. Sapienza has agreements to support language preparation with various language institutes for courses delivered in English. In addition, Sapienza regularly organizes specific seminars on the preparation of slides and their presentation in English. Management of research, knowledge of research systems and funding systems: Sapienza regularly organizes seminars and short courses on the main Italian and European funding programs. The same is true for many of the affiliated offices. It is planned to share the experiences gained in this area both in the context of the agreement based on Sapienza and in the other components of the National Doctorate in Artificial Intelligence. Furthermore, the PhD students in all of which participate in research projects directly. Enhancement of research results and intellectual property: Sapienza regularly organizes seminars and short courses aimed at making students aware of the exploitation of research results, research evaluation, protection of intellectual property and the creation of spin- offs. The same is true for many of the affiliated offices. It is planned to share the experiences gained in this area both in the context of the agreement based on Sapienza and in the other components of the National Doctorate in AI.
