Current projects

  • Setting the strategy to detect and react against invasive forest pathogens in Sweden.  A project funded by Formas.
  • The effect of a changing climate on the geographical distribution of fungal pathogens. Funded by Future Forests.
  • Fungal communities of Scots pine needles – using 454-sequencing to assess the effect of salt and wind exposure and climatic shifts in Europe. The projects are funded by the EU-project BACCARA and Future Forests.

Other research collaborations

  • Preventive and restorative measures to reduce damage on forests -Phytophthora diseases in focus. A Nordic-baltic collaborative project funded by the Nordic Forest Research Co-operation Committee (SNS)
  • Using patterns of annual tree ring growth to reconstruct the spatial and temporal dynamics of historic epidemics of G. abietina. The project is managed by Elna Stenström and funded from Carl Tryggers Stiftelse för Vetenskaplig Forskning.
  • Communities of foliar pathogenic and endophytic fungi in relation to tree species diversities. PhD-project by Diem Nguyen funded by the EU-project FunDivEurope.
  • Monitoring of endophytic and pathogenic fungi in Scots pine needles. PhD-project by Hanna Millberg funded by BACCARA and Future Forests.

PhD project

In november 2009 I defended my PhD thesis with the title 'Litter decomposing fungi in boreal forests -their function in carbon and nitrogen circulation'. In my PhD project I studied the role of litter degrading fungi in carbon and nitrogen circulation in boreal forests. In particular, I focused on the implications of fungal translocation on carbon and nitrogen circulation and the effect nitrogen has on fungal assimilation patterns of carbon.
