Berger has co-authored about 200 publications in international journals and has a citation index of 10,880.
[1] Berger took as the subject of her PhD the electronic properties of AIMn quasicrystals.
)[2] Having studied and produced amorphous films in a postdoctoral position at the Centre D'Etudes Atomiques, she was hired as a researcher at the CNRS's Laboratory for Study of Electronic Properties of Solids (LEPES), where she contributed to the experimental evidence for a metal-insulator transition in the compound quasicrystalline materials grown and characterised at LEPES.
Together with Walt de Heer and Phil First she co-authored the first patent for graphene electronics in 2003.
Her current scientific interests are primarily in the field of nano science and the electronic properties of graphene-based systems.
