About me

  • Senior Consultant and Head of Orthodontic Clinic, Karolinska Institutet, Huddinge, Sweden
    Lecturer at the Orthodontic Unit, Karolinska Institute, Department of Dental Medicine, Huddinge, Sweden

    I am at the orthodontic clinic daily, where I meet my patients and work as a clinical teacher in undergraduate education for dental students in semesters 8 &
  • 9. In addition, as a lecturer at the Orthodontic Unit of the Department of Dental Medicine, I hold lectures and seminars in dental education. Here, I also conduct my research, partly my projects or collaborations with other researchers.


  • In my research, I focus primarily on new digital technologies that use 3D methods and the application of algorithms or artificial intelligence. I use
    these new techniques mainly in clinical projects in the following:
    - Skeletal anchorage, a method where we can control tooth movements with the help of tiny screws in the jawbone.
    - Health economic evaluations, where we analyze what cost or savings the introduction of a new treatment method entails.
    - Registry studies with a focus on epidemiology and socio-economics.
    - Measurement methods with a focus on 3-dimensional techniques.
