Professor
Department of Clinical Dentistry

Job description:

Responsible for education and research concerning biomaterials used in dentistry and the preclinical education.

Head for the reseach group "Biomaterials used in dentistry and medicine" 




Research interests

Main interest: polymer resin based materials, polymerization, degradation and erosion processes, analysis of substances eluted from polymer material (e.g. composites) under different conditions.
In addition  research projects concerning working environment and especially the issue concerning allergy to dental materials among dental personnel and dental technicians but also to some extent in patients are focused on.
