Pauline Gagnon is a Canadian particle physicist and science communicator noted for her long career at CERN and her efforts to explain high-energy physics to public audiences. She worked on experimental programs related to the Large Hadron Collider and the ATLAS experiment and has authored accessible accounts of particle physics developments. Gagnon has bridged research, outreach, and journalism, engaging with communities across Canada, Switzerland, and international scientific networks.

Early life and education

Gagnon was raised in Quebec and pursued undergraduate and graduate studies at McGill University and Université de Montréal, where she studied physics and developed an interest in experimental particle physics. During her formation she encountered research programs connected to facilities such as Fermilab, CERN, and the European Organization for Nuclear Research collaborations, which influenced her decision to pursue a career at international laboratories. Her academic mentors included researchers affiliated with projects like the LEP programme and accelerator initiatives tied to ISOLDE and detector development groups associated with SLAC National Accelerator Laboratory.

Research and CERN career

Gagnon joined CERN as part of the experimental community working on collider detectors and data analysis. She contributed to the development and operation of detector systems within the context of experiments including the ATLAS experiment and engaged with instrument teams that interfaced with collaborators from institutions such as Brookhaven National Laboratory, Lawrence Berkeley National Laboratory, Imperial College London, and University of Oxford. Her technical work involved coordination with trigger and data-acquisition groups and interfacing with physics analysis teams studying signals related to the Higgs boson, searches for physics beyond the Standard Model, and precision measurements linked to electroweak processes first probed at the LEP and later at the Large Hadron Collider. She participated in workshops and conferences alongside delegations from the European Physical Society, American Physical Society, and national funding agencies including Natural Sciences and Engineering Research Council of Canada.

At CERN Gagnon also worked with computing and grid initiatives that integrated services from projects like the Worldwide LHC Computing Grid and institutions that provided high-throughput computing resources such as the Canadian Tier-1 centre and several university clusters. Her collaborations connected experimental analysis pipelines used by groups at California Institute of Technology, Massachusetts Institute of Technology, ETH Zurich, and others in the global particle physics community.

Science communication and outreach

Throughout her tenure Gagnon became a prominent voice for public communication of particle physics, engaging with audiences through lectures, articles, and online platforms associated with major science institutions such as CERN and universities across Canada. She translated complex topics — including accelerator physics, detector operation, and the cultural significance of discoveries like the Higgs boson — for lay readers, educators, and students. Gagnon collaborated with science museums and outreach programs linked to institutions like the Perimeter Institute for Theoretical Physics, Royal Society, and provincial science centres. She has been involved in outreach initiatives that partner with media organizations such as the BBC, CBC Television, and science publishing outlets that serve audiences interested in contemporary physics debates and the societal implications of research at facilities like CERN and Fermilab.

Her outreach work included participation in panels and public events organized by bodies such as the European Commission science policy forums, the United Nations Educational, Scientific and Cultural Organization-linked programs, and national science festivals that assemble speakers from organizations including Nobel Foundation laureates and leading figures from institutions like Stanford University and Harvard University.

Publications and media appearances

Gagnon authored numerous popular articles and explanatory pieces that appeared in venues connected to institutions such as CERN public affairs, university press outlets, and broader media platforms. She contributed to coverage of milestone events including the first runs of the Large Hadron Collider and the discovery announcements associated with the Higgs boson. Her media engagements have included interviews and features with outlets such as Nature, Science (journal), and mainstream broadcasters like BBC Radio and CBC Radio discussing experimental results, science policy, and the human stories behind collaborations involving thousands of scientists from organizations including INFN, DESY, and national laboratories worldwide.

Gagnon has also been cited in educational materials and has provided expert commentary for documentary productions that reference historical experiments like the CERN Antiproton Accumulator era, discoveries at SLAC, and developments in particle detector technology pioneered by groups at Lawrence Livermore National Laboratory and Argonne National Laboratory.

Awards and recognition

For her dual contributions to experimental physics and public engagement, Gagnon has been recognized by scientific and community organizations, receiving acknowledgments from institutional partners including CERN outreach committees, provincial science organizations in Quebec, and national associations that promote scientific literacy. Her work has been highlighted during commemorative events at international conferences such as the International Conference on High Energy Physics and meetings organized by the European Physical Society and American Association for the Advancement of Science.

Personal life and advocacy

Outside of research and communication, Gagnon has advocated for increased participation of women and underrepresented groups in STEM, aligning with initiatives led by organizations like Women in Physics, the Association for Women in Science, and university equity offices at institutions such as McGill University and Université de Montréal. She has mentored students and early-career researchers from programs supported by national agencies including NSERC and participated in panels addressing work-life balance and career development in large collaborations such as ATLAS and CMS.
