The ATLAS Experiment at the LHC
My research focuses on the ATLAS experiment at the proton-proton Large Hadron Collider (LHC) at CERN, in Geneva Switzerland. I have worked on searches for new physics within the Exotics group of ATLAS (more details below) as well as studies of the performance of the muon spectrometer, including an upgraded forward detector (New Small Wheel) whose installation is planned for 2018. Most recently, I have joined the effort to build a new inner tracking detector (ITk) for ATLAS, for the High-Luminosity LHC era.

Long-Lived New Particles
As searches for signs of new, beyond-Standard Model (BSM) new physics (NP) in the most promising signatures of e.g. high pt jets and/or leptons and large missing transverse energy (MET) come up empty, interest in more “exotic” signatures has grown. One such possibility is massive BSM particles with long lifetimes, such that their decay occurs within the ATLAS detector volume, significantly displaced from the interaction point. Scenarios such as this arise, for instance, in gauge-mediated supersymmetry-breaking (GMSB) models and dark-sector models where coupling of dark Z bosons to SM Z bosons is small.
