About us

At CERN the European Organization for Nuclear Research physicists and engineers are probing the fundamental structure of the universe. Using the worlds largest and most complex scientific instruments they study the basic constituents of matter - fundamental particles that are made to collide together at close to the speed of light. The process gives physicists clues about how particles interact and provides insights into the fundamental laws of nature. Find out more on .

Diversity has been an integral part of CERNs mission since its foundation and is an established value of the Organization. Employing a diverse workforce is central to our success.
