    Research interests

    Oral cancer

    Tumor biology

    Oral health

    My interest and research in oral cancer ranges from projects focusing on tumor biology/immunology and prognostic markers to quality of life, rehabilitation and follow-up of treatment related side effects. I also have research projects on oral health and the use of dental services both in the general population and among vulnerable groups.
