Research activity at the INFN is carried out at two complementary types of facilities: the Divisions (Sezioni) and the National Laboratories.
Each of the 19 Divisions is located at a university physics department. The Divisions thus provide a direct connection between the Institute and the academic world. The four Laboratories—in Catania, Frascati, Legnaro, and at Gran Sasso—are home to major facilities which are available to the national and international scientific community.
The INFN workforce includes about 2000 of its own employees, almost 2000 university employees involved in research conducted by the Institute, and 1300 young researchers, including undergraduate and graduate students and research fellows.
