About

Foteini Oikonomou is an associate professor of physics. She is a theoretical astroparticle physicist working to understand how extreme astrophysical environments accelerate particles and radiation to energies exceeding 10^20 electronvolt (more than a million times higher than the energy of protons accelerated at the Large Hadron Collider at CERN). She has advanced the technique of modelling the multimessenger (radiation, cosmic-ray and neutrino) emission of active galactic nuclei which allows astrophysicists to determine the physical conditions in these objects. Her group studies the multimessenger emission of active galactic nuclei and various transient phenomena such as blazar flares and tidal disruption events.
