Currently, my most important research focus is literary multilingualism. I am interested in how (literary) texts deal with (all possible forms of) linguistic diversity and thereby gain politico-cultural agency. In the long term, I am planning a book on the multilingualism of European Romanticism. Another current book project deals with the history of poetry and linguistics in the 19th century (working title: Der Ton der Kultur). It aims at showing how, in both areas, the question how sound can become significant and thereby part of language, articulates fundamental cultural theoretical problems. Other projects are devoted to questions of media didactics and recent media history. In the past, I have worked primarily on literature around 1800, on cultural and literary theory, and on the media of literature. After studying German language and literature, philosophy and mathematics in Bonn and Freiburg, followed by a Fulbright year at the University of Washington in Seattle and a three-year scholarship at the Graduiertenkolleg “Klassizismus und Romantik” in Giessen, I received my doctorate in Siegen in 2007. I then worked as a research assistant at the University of Mainz and headed the DAAD Information Centre in Riga, Latvia, before joining the University of Luxembourg in 2011, where I have been Associate Professor for Modern German Literature and Media Didactics since 2017.
