Christos Leonidopoulos is a Chancellor's Fellow and a Lecturer at the University of Edinburgh.

He received his PhD from Princeton University in 2000, working on Bd mixing and CPT violation searches with the Belle experiment at KEK, Japan. In his thesis he carried out the first experimental test of CPT symmetry in the Bd system and produced the most precise mixing measurement in the world at the time [Int. J. Mod. Phys. A16S1A, 401-403 (2001) and Phys.Rev.Lett. 86 (2001) 3228, a paper with 135 citations].

He then worked on Bd and Bs mixing with the D0 experiment at Fermilab, Chicago as a Research Associate with Columbia University [Phys.Rev.Lett.97:241801 (2006), a paper with 43 citations and Phys.Rev.Lett. 97 (2006) 021802, a paper with 318 citations]. In parallel, he led the integration and commissioning of the Level-2 muon trigger [Nucl.Instrum.Meth. A565 (2006) 463-537].

He moved to Geneva, Switzerland in 2004 as Research Physics Staff with CERN where he worked on building the CMS experiment, and in particular on the design, implementation and commissioning of a novel triggering system known as the High Level Trigger [CERN/LHCC 2007-021, LHCC-G-134 (2007)J.Phys.G34:995-1579 (2007)JINST 0803:S08004 (2008) and JINST 5:T03005 (2010)]. He served as the Deputy Trigger Coordinator for the startup of the LHC and for four years.

In 2011 he received an LPC Fellowship by Fermilab during which he implemented with his team a program of generic searches for new heavy charged bosons, producing the most stringent exclusion limits in the world in several final states [Phys. Lett. B701, 160–179 (2011): a paper with 44 citations, JHEP 08 (2012) 023: a paper with 50 citations, Phys. Rev. Lett. 109, 141801 (2012): a paper with 20 citations, and JHEP 02 (2013) 036, a paper with 8 citations].

He moved to Edinburgh in 2012 with a Chancellor's Fellowship and joined the ATLAS experiment.

His general research interests lie in the Electroweak Symmetry-Breaking mechanism, in Exotica physics searches (such as W') at the LHC, and in hadron-collider triggers. In the next years, together with his research team, he will be focusing on the measurement of the properties of the newly discovered Higgs boson. In parallel, he will continue working on searches for new exotic particles, on upgrading the High-Level Trigger and on R&D for the so-called Level-1 Track Trigger for the ATLAS experiment at the LHC.
