James Proudfoot received his BSc from Edinburgh University in 1974 and PhD from the University of Oxford in 1977 studying proton structure in deep-inelastic muon-proton scattering. He studied electroweak interactions and hadron production in electron-positron scattering with the TASSO Collaboration until 1982 when he joined Argonne and became a member of the CDF collaboration studying proton-antiproton interactions at the Fermilab Tevatron Collider. Among his many leadership roles within the CDF Collaboration, for two years he was Associate Department Head in the CDF Operations department.
With the plan to construct the Superconducting Super Collider (SSC), he led the team to design the barrel electromagnetic calorimeter for the SDC. In 1992, following the cancellation of the SSC, he joined the ATLAS experiment at CERN for which he has been responsible for elements of the design, construction and operation for the central hadronic calorimeter. Currently, he is leader of the ATLAS group in the Division, conducting experiments searching for a deeper understanding of matter and the forces that control our universe at the Large Hadron Collider (LHC) at CERN, Switzerland. His physics research at the LHC focuses on physics signatures making use of calorimeters to measure electrons and jets and to infer the infer the presence of neutrinos in the final state.
