About me

I work as an environmental analyst with a focus on bottom-living plants and animals. My job is to analyze marine monitoring data, communicate research findings to authorities and the public, and to do management related research in the coastal zone.

The projects I am working on at the moment mainly deals with (I) the effect of human activities on aquatic vegetation and associated animals, and (II) the role of vegetation and species interactions for natural values and ecosystem services in the Baltic Sea.

I am on parental leave April to December 2017

Research

The research projects I am working on at the moment are:

  • Benthic vegetation in shallow bays, where we investigate how the vegetation changes with human activities, as well as the vegetation's role for natural values and ecosystem services in coastal areas of the Baltic Sea.
  • Plant-Fish, where we examine the importance of interactions between benthic vegetation and predatory fish for natural values and ecosystem services in coastal areas of the Baltic Sea. Read more on our web
  • Coastal exploitation and marine habitats, where we investigate how human activities affect marine habitats in the coastal environment and what type of habitats that are most affected.
  • Bladderwrack depth distribution, where we study how the depth distribution of wrack (Fucus) has developed in the different sub-basins of the Baltic Sea over the past decade, and possible reasons for the changes. Read more on our web
