Maria Spiropulu is a Greek-American experimental particle physicist known for leadership in searches for new phenomena at high-energy colliders and for contributions to particle detector development and data analysis. She has held positions at major research institutions and collaborations that include CERN, Fermilab, Stanford University, and Caltech, and has collaborated with experiments such as CMS and projects related to the Large Hadron Collider. Her work spans experimental design, phenomenology, and technology transfer between fundamental physics and industry.

Early life and education

Born in Greece, Spiropulu completed undergraduate studies at the National Technical University of Athens before relocating to the United States for graduate education. She earned her Ph.D. at the Massachusetts Institute of Technology where she worked on topics connected to collider physics and detector instrumentation. During her graduate and postdoctoral years she interacted with researchers and institutions including CERN, Fermilab, Princeton University, Harvard University, and colleagues in collaborations tied to experiments at the Tevatron and preparations for the Large Hadron Collider. Her formative mentors and collaborators have included faculty and scientists from MIT and Caltech research groups as well as international teams from INFN and DESY.

Research and academic career

Spiropulu's academic appointments have included roles at Princeton University as a postdoctoral researcher and later faculty appointments at Caltech and Stanford University, with visiting and adjunct associations at CERN and Fermilab. She served in leadership positions within the CMS collaboration at the Large Hadron Collider, coordinating analyses and detector commissioning alongside groups from University of California, Berkeley, University of Chicago, Columbia University, and University of Oxford. Her research program has integrated work on tracking detectors, calorimetry, and trigger systems with software and statistical analysis approaches developed in concert with teams from SLAC National Accelerator Laboratory, Brookhaven National Laboratory, Lawrence Berkeley National Laboratory, and industrial partners. She has been involved in cross-disciplinary initiatives with researchers at Stanford Linear Accelerator Center and worked on projects that connect fundamental physics to applied science in collaboration with NASA-affiliated laboratories and technology transfer offices.

Major contributions and discoveries

Spiropulu is recognized for leading and contributing to prominent searches for physics beyond the Standard Model at the LHC, including extensive searches for supersymmetry and signatures of dark matter production in proton–proton collisions. Her analyses have used final states with missing transverse energy, jets, leptons and photons, implemented using techniques influenced by work from groups at CERN, Fermilab, and DESY. She played a key role in implementing data-driven background estimation methods and multivariate techniques developed in collaboration with researchers from MIT, Caltech, Princeton, Harvard, and Yale University. Beyond analyses, she contributed to detector performance studies and upgrades connected to CMS subdetectors and to the global effort that produced the discovery of the Higgs boson alongside collaborators from ATLAS, CMS, Peter Higgs-related theory groups, and experimental teams from Imperial College London and University College London. Her work has bridged collider phenomenology communities involving theorists from CERN theory division, Institute for Advanced Study, and Perimeter Institute.

Awards and honors

Spiropulu's accomplishments have been recognized by awards and invited positions from institutions and societies including American Physical Society, national laboratories such as Fermilab and SLAC, and academic honors from Caltech and Stanford University. She has been invited to speak at major conferences and workshops such as International Conference on High Energy Physics, Lepton-Photon Conference, and meetings organized by Europ. Org. for Nuclear Research panels and committees. Her leadership in large collaborations has led to committee appointments and editorial roles connected to journals and organizations like Physical Review Letters and society panels at APS.

Teaching, mentorship, and outreach

As a professor and mentor at institutions including Caltech and Stanford University, Spiropulu has supervised graduate students and postdoctoral researchers who have gone on to positions at CERN, Fermilab, Brookhaven National Laboratory, and universities such as MIT, Princeton, and University of California, Berkeley. She has taught courses and developed curricula that interact with programs at SLAC, Kavli Institute for Theoretical Physics, and summer schools sponsored by ICTP and Perimeter Institute. Her outreach activities include public lectures and participation in initiatives with museums and science centers such as the American Museum of Natural History and collaboration with science communication efforts at NOVA and public broadcasting events associated with PBS-affiliated science series.

Selected publications and collaborations

Spiropulu has authored and coauthored numerous peer-reviewed articles and conference contributions in journals such as Physical Review Letters, Journal of High Energy Physics, Physics Letters B, and proceedings of the International Conference on High Energy Physics. Her collaborative work often lists large author teams from CMS, with coauthors affiliated with CERN, Fermilab, Brookhaven National Laboratory, University of Oxford, ETH Zurich, University of Tokyo, Seoul National University, University of Melbourne, and many other institutions. Key collaborative efforts include analyses with members of the ATLAS and CMS collaborations, joint workshops with theorists from Institut des Hautes Études Scientifiques, Perimeter Institute, and technology partnerships involving Siemens-like industrial entities and national funding agencies such as NSF and DOE.
