During the last decade I have mainly work on three projects. In the first I have mapped Viking Age objects with provenance from the Finnish mainland found in the Mälaren Valley. A large number of excavations have been undertaken in the Mälaren area in recent decades and the archaeological record has improved significantly. One aim of this project has therefore been to process the information now at hand. This means that I have analyzed find contexts and find combinations for Finnish objects as well as the provenance of other objects found in the same grave or on the same site. The analyzes have provided a basis for discussions about the cultural identity and group affiliations of the buried persons as well for the interaction that took place between the Mälaren region and mainland Finland during the Viking Age. Especially pottery of a Finnish type found in the Mälaren region indicates well-developed interaction between the two areas.

The second project concerns various aspects of Iron Age and early medieval Blekinge, Sweden. Also in Blekinge the archaeological record has improved lately and the history of the region needs to be rewritten. The starting point for my contribution has been studies of the central place Västra Vång, the Johannishus hoard, the burial ground Store Backe as well as recently discovered archaeological finds from the island of Öppenskär.  

The third project relates to aDNA analyzes made for the mapping of the Viking world genome. The produced data means that there is a large amount of research material that can be used to undertake novel case studies. Together with Helene Wilhelmson I will undertake two case studies the first based on individuals with smallpox virus. Southern Scandinavia has shown the largest concentration of smallpox virus in Viking Age Europe. We will analyze some of the individuals carrying this virus in order to establish who they were and how the virus affected their health and status. We will also discuss the impact this disease had on a local level in society.

The mapping of the Viking world genome also showed that a few regions, primarily the island of Öland, had a very high proportion of non-locals of diverse geographical origin. In our second case study we want to investigate who the people migrating to Öland were, where they came from and why they came.
