I find almost all geology interesting and that probably explains the variation in my research activities. The main interests throughout the years have been and still is geochronology, metamorphic petrology and mineralogy. I did my phd-thesis work in the Scandinavian Caledonides. The thesis (1986) included papers on geochemistry, metamorphic petrology, structural geology and geochronology. Thereafter, research have mainly been focussed on geochronology and petrology problems in the high grade gneiss terrain in SW Sweden.
In 2007 a new project started in collaboration with the carbonate rock industry. The aim of the four year project was to minimize production losses during calcination of limestone and dolomite and thereby the emission of CO2, other gasses and particles. In 2014 this project was followed by  a second industrial oriented research project with focus on chemistry of carbonate rocks. I have also participated in an inspiring collaboration initiated by a microbiologist on the interaction between biota and minerals. If time permits and opportunities are given I would like to do more work on geosphere-biosphere interactions and environmental related geology.
