The goal of the Ph.D. in Engineering in Computer Science is to train: i) experts in computer science and engineering able to develop new technologies and methodologies both in the academia and in public and private research institutions; ii) specialists of very high professional level with engineering skills able to transfer technological and methodological advances into leading application sectors such as informatics and robotics, in industrial contexts, as well as in services, and public administration. Areas of interest of the Ph.D. in Computing Science and Engineering include: Computer architectures and networks; Algorithm engineering and complexity analysis; Software engineering; Artificial intelligence; Knowledge representation; Artificial Intelligence and Robotics; Information systems; Databases; Distributed Systems; Web and social networks; Software oriented computing; Cyber security and intelligence; Computer vision and computer graphics; Natural Language Processing; Human-computer interaction; Multi-agent and Multi-robot systems. The overall activity of Ph.D. students during the three years of the Ph.D program can be quantified in 180 ECTS credits (simply ECTS in the following), 30 of which (corresponding to 50% of work load of one year) are devoted to studying, and 150 of which (corresponding to one year and a half of work) are devoted to carrying on research and writing the thesis. The credits are divided as following: A 0-30 credits for completion of the curriculum of basic studies, chosen from the regular courses from the graduate and undergraduate curricula offered at Sapienza. The Admission Commission makes a proposal for the assignment of credits of type A. B 12-18 credits for specialized modules offered by the Doctorate, by the Master Programmes or for courses offered by qualified institutions requiring a final exam, that must be approved by the Board of Lecturers. C 12 credits for the attendance of summer schools, tutorials at conferences, and departmental seminars (usually on the basis of 0.5 credits for each 1 hour seminar), in order to ensure the integration of the post-graduate students in the life of the department and the development of multi-disciplinary competence in the various research areas of Engineering in Computer Science.
