Dr. Niki Saoulidou is an Assistant Professor at the Department of Physics, National and Kapodistrian University of Athens specializing in Experimental High-Energy Physics.

Research Interests

The field of research of Assist. Prof. Saoulidou is Experimental High Energy Physics. She studies the properties and interactions of elementary particles in neutrino experiments in the past, and since 2009 in collider experiments (pp) at the LHC accelerator at CERN. She participates in Standard Model physics analysis (QCD) as well as searches for new physics beyond the Standard Model and in particular Supersymmetry.

Short Bio

Assist. Prof. Saoulidou received her degree (1996) and her PhD (2003) from the Department of Physics of the University Athens, Greece working on the DONUT (Direct Observation of the tau Neutrino) experiment at Fermilab (Fermi National Accelerator Laboratory), USA. This experiment directly observed the tau neutrino, the last one of the known elementary particles of the Standard Model. In 2003 she moved to Fermilab, USA to work as a postdoctoral research associate in the MINOS (Main Injector Neutrino Oscillation Search) experiment, which confirmed neutrino oscillations with accelerator neutrinos. In 2006 she became a Fermilab Wilson Fellow and continued her research in MINOS, NOvA (Numi Off-axis nue Appearance) as well as in the planning of future long baseline neutrino experiments in the USA. In 2009 she transitioned from neutrino physics to collider physics and was relocated, as a Fermilab Wilson Fellow, at CERN (Geneva, Switzerland) in order to work on the CMS experiment. In spring of 2011 she returned in Greece as an Assistant Professor in the Sector of Nuclear Physics and Physics of Elementary Particles of the Physics Department at the University of Athens, Greece.

At CMS Assist. Prof. Saoulidou initially worked in the analysis of the first experimental data studying the characteristics of jets. She developed the jet identification criteria now used by all CMS physics analyses. [2010-2012 co-Convener of the "Jet Algorithms" group of CMS (Physics Object Group) in charge of the study and monitoring of jet characteristics, and the determination of the jet energy resolution]. The jets were then utilized to perform measurements of Quantum Chromodynamics [2012-2014 co-Convener of the CMS Physics Analysis Group (PAG) "Standard Model Physics with Jets"]. Since 2014 Prof. Saoulidou uses dijet events to search for Dark Matter, extra dimensions, W', Z' etc hunting for resonances (wide and narrow) in the dijet mass distribution [2014-2017 co-Convener of the CMS PAG "Exotica searches with Jes+X"].
