Om mig

After completing the study program in nursing (1987) and the study program in dentistry (1993), I worked as a hospital dentist and clinical teacher at Karolinska Institutet with special interest in oral medicine. In 2019 I became a specialist in orofacial medicine. I undertook my PhD education at Karolinska Institutet and defended my thesis in 2011. The title was ​"Conditioning associated effects on oral mucosa and salivary secretion in allogeneic stem cell recipients", supervised by Professor Göran Dahllöf, Professor Anders Heimdahl and Professor Olle Ringdén. Since around 2000, I have been a lecturer at the Department of Dental Medicine and have since 2012 focused on oral medicine and clinical oral pathology education of dental, dental hygienist and continuing professional education dentists. In 2015, I was appointed as Program Director for the study programs in Dentistry and the Complementary Program for Dentists outside EU/EES and Switzerland. I have since then been heavily involved in the development and implementation of the new dental program study plan. Alongside my teaching and mentoring activities for the undergraduate education, I am supervisor for several students in the dental Specialist Training Program, as well as supervisor for PhD candidates. 


Current research focuses on developing pathological diagnostics and understanding disease processes in the soft tissues of the oral cavity. We are concerned with the complications that result following hematopoietic cell transplantation in the form of Graft versus Host Disease (GVHD). Oral manifestations are one of the most common and debilitating complications with the histopathology poorly understood, particularly associated with long-standing chronic (c)GVHD. Our ongoing studies are working to understand oral mucosal and salivary gland cGVHD pathogenesis, clinical and diagnostic criteria and the search for predictive biomarkers. 

Additional, studies are examining other debilitating chronic oral complications after high-dose chemotherapy and/ or stem cell transplantation, for example the necessity for transfusion of platelets before invasive dental procedures and the development of surgical techniques in patients treated with bisphosphonates.

We also aim to find out more about the pathogenesis and clinical pattern of different oral mucosal lesions as, white snuff induced oral lesions, aphthous stomatitis and oral manifestations in patients suffering from inflammatory bowel disease, where we strive to progress the management. Currently we are doing a screening study of the dental status in patients with X-linked hypophosphatemia.
