Being a biologist, I early concentrated my work on wild game - elk, beaver, bear and reindeer. I also studied ritual behaviour of Sámi involving bear and reindeer. Bear is still in focus. Later, I changed my interest towards the people themselves. I initiated the project Medieval people, where my focus is children. Another interest is the biological background of ethnic groups and the relation beteween biology and culture within studies of ethnicity. This was my focus in the South-Saami project, where I was one of the leaders.
Lately, I have been very interested in ethical questions within archaeology and osteology. I have been teaching these subjects in the department but also inititiated research projects on the Anatomical collections of our university. I have further debated the collections not least in public media.
Another theme is the plague in 1709-10 in Scania, where a scientifically broad team will try to spot the first aDNA evidence in the Nordic area of Yersinia pestis.
