She obtained the dr.philos. degree at the University of Oslo in 1998, with the dissertation ''Rimelig ut fra sakens art. Om tolkning av ubestemte adjektiv i regelgivende språk''. She has been responsible for a large project on the lexicography of bokmål (Det leksikografiske bokmålskorpuset; LBK) since 2000. She has also served as the expert adviser on language to the Norwegian Broadcasting Corporation.

In 2013, she was elected as the Pro-Rector of the University of Oslo, its second highest position, for the term 2013-2017. However, in 2014 she resigned from her position as Pro-Rector, citing harassment of her by Rector Ole Petter Ottersen and stating that she was deprived of most responsibilities associated with her position as the university's Pro-Rector and not involved in the decision-making process.
