Her research is mainly located in Discourse Studies (DS) and in Critical Discourse Analysis (CDA). Together with her former colleagues and Ph.D students in Vienna (Rudolf de Cillia, Gertraud Benke, Helmut Gruber, Florian Menz, Martin Reisigl, Usama Suleiman, Christine Anthonissen), she elaborated the Discourse Historical Approach, an interdisciplinary, problem-oriented approach to analysing the change of discursive practices over time and in various genres.
She is member of the editorial board of a range of linguistic journals, co-editor of Discourse and Society, Critical Discourse Studies, and of the Journal of Language and Politics. She was the founding editor (together with Paul Chilton) of the book series Discourse Approaches to Politics, Society and Culture. She was also section editor of "Language and Politics" for the Second Edition of the Elsevier Encyclopedia of Language and Linguistics. Ruth Wodak chaired the Humanities and Social Sciences Panel for the EURYI award, in the European Science Foundation from 2006 to 2008.
