I am professor in General Linguistics at the University of Helsinki. My primary research fields are language typology taking a broad cross-linguistic comparative perspective and language documentation and description. My research interests include negation, interrogatives, language complexity, typological theory and methodology. The focus of the documentary and descriptive work is on the Skolt Saami language spoken in northern Finland. My teaching includes courses on a wide variety of linguistic topics ranging from general theory and method to specific themes related to my research interests. I supervise theses mainly on subjects related to my own research foci, but also on many other general linguistic themes.
