Physics at colliders
I have been involved in the ATLAS experiment at the Large Hadron Collider (LHC) since 1999, when that experiment was still in the R&D phase. Part of my research has been development, assembly and operation of the precision semiconductor strip detectors. These micron-precision devices reconstruct tracks from particles produced in the very high energy collisions at the LHC, taking 40 million snapshots per second.
A separate thread of my research has been searching for signatures of new particles – particularly Higgs bosons and dark matter particles. As well as searching for (and helping occasionally find) new particles, I have developed many of the techniques which are used to measure their properties – such as their mass, angular momentum and decay modes.
A further area of my work has been on probing the foundations of quantum theory at high-energy colliders, using techniques from the world of quantum information theory to perform quantum state tomography, entanglement detection and to perform "Bell" tests of local realism
Looking towards the future, my group is also exploring the physics potential of the FASER-2 experiment at the CERN Forward Physics Facility and of future colliders.
