Arvanitaki's work has focused on finding novel experiments to explore topics in theoretical physics.
[1] In 2016, Arvanitaki, Savas Dimopoulos and Ken Van Tilburg proposed a method of detecting dark matter as a matter wave, using conventional gravitational wave detectors.
[4] She has proposed using the Advanced Laser Interferometer Gravitational-Wave Observatory to observe the gravitational waves from black hole collisions to detect the presence of QCD axions, a candidate for explaining dark matter.
[5] She has also proposed using neutrino and gamma-ray telescopes, such as the Fermi telescope, Hess, or IceCube, to search for dark matter decay products predicted by certain theories of super-symmetry.
Arvanitaki suggested naming the chair for Aristarchus — the ancient Greek astronomer who surmised that the Earth rotated around the sun centuries before Coperniucs — in a nod to the cosmological scope of her research, the Greek background of the Stavros Niarchos Foundation, and her own Greek origin.
