My main research interests lie in the area of interactional linguistics. In particular, I have worked on referentiality and the use of person forms in interaction. My doctoral dissertation examined the use of second person singular forms in Finnish everyday conversations. In addition, I have also studied the use person form more generally, especially the open use of person expressions, and examined the question of units in language and interaction from the point of view of fixed expressions.

My current research projects focus on the fixed use of verbal constructions expressing person, referential expressions in psychotherapeutic interaction, and the linguistic and interactional means of creating and modulating participation in Finnish everyday conversations. I am also associated with a group of researchers (DanTIN, Aarhus University) working on a grammatical description of Danish talk-in-interaction.
