Dr. Stephen Magill is an Experimental Particle Physicist in the High Energy Physics (HEP) Division at Argonne National Laboratory (ANL) with expertise in calorimetry and electromagnetic particle interactions in matter.  He has served for many years as a member of the International Advisory Committee for the Calorimetry in High Energy Physics international conferences.  His physics interests include jet physics with expertise in extreme QCD, particle reconstruction with expertise in Particle Flow Algorithms, and in understanding basic properties of neutrinos.  He is currently a member of the NOvA Experiment, having served as Run Coordinator during the installation and commissioning phase; the Mu2e Experiment, coordinated test beam efforts for the Cosmic Ray Veto (CRV) detector; and the future DUNE experiment, currently physicist in charge of Cathode Plane Array (CPA) production for the ProtoDUNE Single Phase Detector.  Publications include contributions to more than 250 papers on deep inelastic scattering and QCD, detector simulations and particle flow algorithms, and long-baseline neutrino oscillations.  As an ANL staff member, he has supervised both graduate and undergraduate students and postdocs in detector construction and physics analysis and has coordinated detector upgrades, supervising engineers and technicians, both at ANL and internationally. He has obtained grants for innovative, new direction R&D projects, including a DOE Collider Detector R&D grant which led to the idea of using nanoparticles to create thin, UV-sensitive photosensors for measurement of Cerenkov light from a crystal. He has formed collaborations with university partners to explore the use of nanoparticles as UV sensors - first with the University of Illinois at Champaign-Urbana, and currently with the University of Texas at Arlington.
