Computer Science PhD

As a PhD student, I work in a very friendly environment, with members of staff always ready to assist me. From the very beginning the department and the University has offered me all the equipment and support that I needed to start my research project. Moreover, the department, through the seminars and the annual conference that it holds, is giving me all the essential experience to become a skilled researcher.
