Her research interests and work are concerned with grammar and grammatical categories, mostly (but not exclusively) within the framework of Systemic Functional Linguistics. Together with Thomas Hestbæk Andersen, she has authored a book on Danish grammar described within the framework of SFL, and she is currently writing a SFL-grammar of German together with Uwe Helm Petersen. She has published several papers dealing with (grammatical) categories in SFL (e.g. projection, clause complex, fact-clause) as well as their application in descriptions og Danish and German grammar.
