About
Nikos Varelas is Vice Provost for Academic Programs and Effectiveness and Liberal Arts and Sciences Distinguished Professor of Physics. Prof. Varelas’ research field is experimental high energy particle physics. His research interests concentrate on precision measurements of Quantum Chromodynamics, the theory that describes the strong interaction responsible for the nuclear force; searches for more fundamental building blocks of matter beyond the quarks and leptons in the Standard Model; searches for large extra spatial dimensions, quantum black holes, dark matter; and on studies of the Higgs boson. Prof. Varelas is currently working on the CMS experiment at the Large Hadron Collider (LHC) at CERN in Switzerland. He was a member of the team that discovered the Higgs boson in 2012. His group's technical contributions at CMS have centered on the development and operations of the Level-1 Calorimeter and High-Level Trigger Systems.
Prof. Varelas has served as the co-spokesperson of the Coordinated Theoretical-Experimental Project on QCD (CTEQ) Collaboration, member of the Executive Committee of the American Physical Society’s Division of Particles and Fields, Chair of the Fermilab Users Executive Committee, and Senior Fellow of the LHC Physics Center at Fermilab.
Prof. Varelas is a Fellow of the American Association for the Advancement of Science and a University of Illinois Scholar.
