Dr Lily Asquith
University of Sussex
The term 'physicist' covers an enormous number of very different sub-fields, from the study of materials to the study of the expansion of the universe. My sub-field is high energy particle physics, which is often abbreviated to HEP. Within HEP one is either an experimentalist (like me) or a theorist. It is the experimentalists' job to design and build particle detectors, to collect data, and to interpret the data in a sensible and useful way. It is common for a particle physicist to become closely affiliated with a single experiment for a period of some years while that experiment is active. I became a member of the ATLAS collaboration as a PhD student. Most of my time is spent on data collection and analysis. I am particularly involved in the reconstruction of energy deposits as jets, establishing the use of algorithms and techniques that exploit the finer details of particle jets (jet substructure) as a tool for making precision measurements of known particles and processes, and for discovering new ones. From 2015 I will be focused on searching for undiscovered massive particles decaying to boosted (very high energy) vector bosons, and on careful observation of the behaviour of the newly-discovered Higgs boson. These searches and measurements, along with those being done by my 3000 colleagues on ATLAS, have the potential to shed light on some of the most curious open questions we have about our universe.
