Cooperation between nations, universities and scientists is the driving force behind CERN’s research.

As of 2017, more than 17 500 people from around the world work together to push the limits of knowledge. CERN’s staff members, numbering around 2500, take part in the design, construction and operation of the research infrastructure. They also contribute to the preparation and operation of the experiments, as well as to the analysis of the data gathered for a vast community of users, comprising over 12 200 scientists of 110 nationalities, from institutes in more than 70 countries.

Coming to CERN as a young graduate student changed my life. I met the best people, worked with leading scientists and spent the most memorable months of my life there. My experience at CERN had a huge impact on my career and I am now a member of the Lindau Nobel Laureates Meetings.
