Professor Hofman presently carries out his research at the Relativistic Heavy Ion Collider (RHIC) accelerator at Brookhaven National Laboratory in New York and the Large Hadron Collider (LHC) accelerator at CERN in Switzerland.
His research at RHIC is carried out within the PHOBOS and STAR collaborations, studying a new phase of matter, called the "quark gluon plasma", which is believed to have existed at the birth of our universe. His research at the LHC is carried out within the CMS collaboration.
Professor Hofman is currently the co-convenor of the PHOBOS multiplicity working group and responsible for the heavy-ion level-1 triggering in CMS.
Professor Hofman was also project manager for the PHOBOS collaboration during the RHIC Run 3 (Dec2002-Aug2003) and project leader for the LEPPEX collaboration which performed experiments in at the Argonne Tandem-Linear Accelerator System (ATLAS) (1998-2001).
Professor Hofman was also a member of the E917 collaboration which measured relativistic Au + Au collisions at 6, 8 and 10.8 AGeV at the AGS (1997-2004).
