Following his doctoral work, Brock was a research associate at
Fermilab from 1980 to 1982. In 2011, he was named a University Distinguished Professor. He subsequently became a member of the
DØ collaboration, a
proton–
antiproton colliding beam experiment at Fermilab. Additionally, he also joined the
ATLAS collaboration at
CERN, a
proton–proton collider experiment at the
Large Hadron Collider. The task force released their final report in December 1998, recommending no overall statement on tenure, but that the APS should encourage more transparency in tenure requirements. He was later made chair of the APS' Division of Particles and Fields in 2010 and was chair of the U.S. ATLAS Institutional Board from 2014 to 2015. From 2010 to 2013, he was the U.S. at-large representative to the International Committee on Future Accelerators. He co-led the Energy Frontier working group for the 2013
Snowmass study on the future of U.S. particle physics. == Awards and honors ==
