Foteini Oikonomou

Foteini Oikonomou is an Associate Professor at the Department of Physics, Faculty of Natural Sciences, Norwegian University of Science and Technology (NTNU). She specializes in theoretical astroparticle physics, focusing on extreme astrophysical environments that accelerate particles to energies exceeding 10²⁰ eV.

• Current research includes multimessenger emission modeling of active galactic nuclei
• Expertise in cosmic ray acceleration and high-energy neutrino origin
• Active in teaching advanced astrophysics and particle physics

Her work bridges astrophysics, particle physics, and cosmology, with particular attention to blazars, tidal disruption events, and ultra-high-energy cosmic rays. She contributes to major collaborations like GRAND and GCOS, developing future instrumentation for astroparticle detection.

Recent publications explore cosmic ray propagation in diverse source populations, neutrino emission from transient astrophysical phenomena, and magnetic field line effects on particle acceleration. Her research has been featured in journals such as Nature Reviews Physics, Physical Review D, and The Astrophysical Journal.

She teaches AST-3451 Astrophysics II and has previously taught particle physics (FY3403/FY8913) and general astrophysics (FY2450). Her outreach includes public explanations of ultra-high-energy cosmic ray research through popular science articles.
