Sinead Farrington is an experimental particle physicist with interests across collider physics as a means of understanding the most fundamental particles and their interactions. Sinead currently leads the UK effort in the ATLAS collaboration at the LHC at CERN. She led ATLAS searches for the Higgs boson decaying to tau leptons and now searches for exotic particles. Sinead collaborated in discoveries in the CDF collaboration at Fermilab, USA. She serves on STFC’s Project Peer Review Panel and the European Committee on Future Accelerators. She was awarded the 2021 Physical Sciences Laureateship, Blavatnik UK New York Academy of Sciences prize.
