The PhD in Computer Science aims to prepare PhD researchers in all major areas of Computer Science research. The PhD aims to provide high-quality training in line with the highest international standards. The PhD College includes among its members the winners of ERC grants, IBM Faculty Award, Google Faculty Awards, Google Focused Awards, and Marie Curie Fellowship. Our PhD researchers must be able to independently carry out and coordinate research activities in the academic world or international research institutes. Depending on their training, they should also be able to conceive and direct innovative computer system development projects to address complex, interdisciplinary problems emerging in cutting-edge industrial spheres. To this end, PhD candidates must acquire a solid foundation in both the fundamentals and applied aspects of various fields of Computer Science, understand thoroughly the scientific method of investigation, comprehend and utilize the methodological tools of other disciplines that support Computer Science and its applications, learn to evaluate, understand and interpret problems, even complex ones, characteristic of various application fields. In recent years, more specific research, teaching, and seminar initiatives have been undertaken to deepen candidates' knowledge in the areas of networks, distributed algorithms, theoretical computer science, software engineering, computer security, big data, artificial intelligence, and computer vision. This is a natural consequence of the strong interest that these areas have among the College's members, substantiated and supported by numerous international awards and the presence of substantial funding obtained in this area through national and European projects. Some projects, such as European Centers of Excellence networks, Erasmus+ and Erasmus Mundus programs, the Vinci program, provide specific funds to allow PhD students to spend short periods at the locations of other entities participating in the Centers of Excellence network. In general, participation in research activities financed nationally and in Europe helps to deepen the competencies of PhD students in areas of particular theoretical and practical relevance, and collaboration with researchers from other institutions. Therefore, participation in funded projects is encouraged, considering it to have a significant educational impact. Also, training activities aimed at supporting the development of cross-cutting skills (ability to write and manage research projects on competitive calls, ability to develop innovation in its various declinations ranging from innovative entrepreneurship to the generation, protection, and exploitation of intellectual property) are provided.
