Particle physics research is both international and collaborative, with large national laboratories working together to most efficiently advance science. Joel Butler, Fermilab distinguished scientist, is the leader of the CMS experiment at the CERN laboratory in Europe.

Fermilab’s Greg Rakness is a hero of the LHC for his work in organizing the commissioning and operations of CMS, one of the two big detectors at the Large Hadron Collider at CERN.
