The EPFL offers 13 complete courses of study, from bachelor to master. Its five faculties (computer and communication sciences, science and engineering, basic sciences, life sciences, natural and built environment) bring together nearly 10'000 students and researchers, as well as 1'400 PhD students. Nearly 125 nationalities are represented here. The EPFL promotes meetings between students, teachers, researchers and entrepreneurs, thus facilitating the emergence of new projects in the fields of science, technology and architecture. Good examples of this are the SwissTech Convention Center, inaugurated in 2014, which houses a 3'000-seater conference hall in an ultra-modern setting, the Alinghi yacht, the Solar Impulse solar aircraft and the Human Brain project, a study of how the brain works involving numerous European laboratories.
