Ph.D., Associated researcher
(retired senior researcher)
See the Staff and Contact page
My research is concerned mainly with the Precambrian geological evolution of the Fennoscandian Shield, and the relation between Fennoscandia / Baltica and other Precambrian shield areas and cratons, such as Laurentia (North America), Amazonia and West Africa. Working methods include geochronological (U-Pb), isotope geochemical (Rb-Sr, Sm-Nd) and geochemical investigations of relevant rocks. I have worked with rocks in southern Sweden (Blekinge, the Protogine Zone, the southern part of the Sveconorwegian province) and the Danish island of Bornholm, as well as the Svecofennian bedrock in east-central Sweden. In addition, I have previously worked with the Caledonian bedrock on Svalbard.
I formally retired on 1 September 2022 after 38 years at the Swedish Museum of Natural History, but will continue as an associated researcher writing up some projects and papers, as well as finishing the popular science book about the geology of Sweden that I have been involved in for several years.
