She studied classical philology, education and German studies at the Universities of Marburg and Göttingen. From 1967 to 1969 she lived in Ithaca, New York, and in 1972 she moved with her then husband Adolf Muschg to Kilchberg, Zurich, where she still lives today.
Johansen began her literary career as a translator of American avant garde authors, and soon moved on to original work, particularly stories for children. She published her first novel in 1978. She is a member of PEN Switzerland and of the Deutschen Akademie für Sprache und Dichtung in Darmstadt.
