Biography
Professor Varelas' research interests center on precision studies of Quantum Chromodynamics (QCD) and on searches for the Higgs Boson at hadron colliders. He is a member of the D-Zero experiment at the Tevatron Collider at Fermi National Accelerator Laboratory in Batavia, Illinois, and of the CMS experiment at the Large Hadron Collider at CERN in Geneva, Switzerland. His technical contributions to D-Zero center on the Trigger System. He served as Trigger Coordinator for the D-Zero experiment, Co-Project Manager of the Trigger Upgrade for the Run II, and Chair of the Trigger Board. He has also served as co-convener of the Higgs Physics Group in Run II and co-convener of the QCD Physics Group in Run I. At CMS he has served as co-convener of the Jets and Missing-ET Physics Object Group and currently serving as co-convener of the QCD Physics Group. Professor Varelas is also a member of the Coordinated Theoretical-Experimental Project on QCD (CTEQ) Collaboration.
