The structure of the habitat and surrounding landscapes are crucial for the biodiversity and interaction among species. My research have mainly focused on landscape ecology, population dynamics and risk of infestations and infections of parasites. Current research questions involves forest structures in woodland key habitats and invasive tree species and how it affect biodiversity.


Since I defended my thesis on population dynamics of the spruce bark beetle Ips typographus during outbreaks, I have been doing research on forest restorations and bark beetle diversity (SLU, Umeå) and how environmental factors affect a deadly fungus Batrachochytrium dendrobatidis that infect amphibians (Uppsala University, EBC). At this department (Department of Ecology, SLU), I am working in Joachim Strengbom’s research group, where I will evaluate how forest structures and landscapes affect biodiversity in woodland key habitats.



Mainly courses in entomology and herpetology


- Woodland key habitats and effects on biodiversity 

- Distribution of the chytrid fungus in nordic amphibians

- Habitat choice and movements in reptiles and amphibians

- Forest restorations and effects on bark beetle diversity

- Outbreak dynamics of the spruce bark beetle Ips typographus

Are you looking for a masterproject? I have projects focusing on the population dynamics of the spruce bark beetle and its natural enemies. You will work i close collaboration with the Swedish Forest Agency and other forest stakeholders, which may open doors for your future work as i biologist or similar. Please send an email to me if you are interested.
