The Department of Computer Science

Founded on January 1, 1992 under the initiative of a group of professors from the Department of Mathematics “Guido Castelnuovo” with backgrounds from a variety of fields such as physics, engineering, and mathematics, the department is set on building upon the scientific and mathematical backgrounds of the founders. The department became the first center in greater Rome dedicated to the study of theoretical and applied computer science and today is a reference point for well-prepared students to jump into  the evolving field of Information and Communications Technology. 

The department is internationally recognized as a center of excellence in many of the most important current areas of research in Computer Science.


Rome, Italy is the host city of Università di Roma “La Sapienza”. Rome offers many advantages as a location. It is readily accessible -at affordable prices- internationally and directly from all major European air hubs (e.g. London, Frankfurt etc.). Rome is also accessible from the Americas, Asia, Africa and Middle East.
