I research how language changes in a multimodal online environment and how it adapts to its specific circumstances. My interests in this area include vocabulary and lexical innovation,  the use of English as a Lingua Franca, multimodality, business discourse, and social media discourse. I also investigate and teach the use of online media and corpora in the EFL classroom, integrating intercomprehension and intercultural approaches.

After several earlier studies on historical linguistics, particularly the development of multi-word verbs, I have published on online discourse, language and modality, language and food. Recently my research has focused on business communication in social media and multimodal discourse, particularly paralanguage and gestures.

I am professor of International Business Communication and Digital Business at Trier University of Applied Sciences and associate professor of English linguistics and corpus linguistics at P faculty, Saarland University, and at Faculty I, Technical University Berlin. In the Institute for International and Digital Discourse, I head our applied language and communication program and several research projects on online and business discourse.

I currently also hold the office of Vice-President | Research at Trier UAS.
