Constantia Alexandrou (Greek: Κωνσταντία Αλεξάνδρου) is a Cypriot physicist whose research focuses on lattice QCD, including the use of lattice QCD to elucidate the proton spin crisis.
Alexandrou read physics at the University of Oxford, receiving a bachelor's degree there with first class honours in 1980.
[2] In 2022 she was elected for a two-year term as chair of PRACE, the Partnership for Advanced Computing in Europe.
[5] In 2019, Alexandrou received the International Fellow Award of the Helmholtz Association, funding a research visit to DESY in Germany.
[1] She was elected as a Fellow of the American Physical Society in 2024, after a nomination from the APS Division of Nuclear Physics, "for the pioneering contributions in calculating nucleon structure observables using lattice QCD".
