My primary interest is understanding genetic and genomic mechanisms related to fungal host interactions (parasitic as well as symbiotic). Typically I am applying genomics and transcriptomics approaches coupled with bioinformatics analyses to provide novel insights into fungal host interactions. I have been studying the infection biology and evolution of parasitism among nematode-trapping fungi.

I got my PhD at Microbial Ecology, Lund University 2002 with professor Anders Tunlid as supervisor. I worked briefly as senior scientist at the bioinformatics company BioBridge Computing AB. I later did my post doc at the European Bioinformatics Institute (EBI). I returned to Microbial Ecology and am now working with genome evolution of nematode-trapping fungi and the symbiosis of ectomycorrhizal fungi

I am also working together with Katarina Hedlund, Sandeep Kushwaha, Tejashwari Meerupati, and Lokeshwaran Manoharan on a targeted metagenomics project to study the functional diversity in soil.

I support bioinformatics primarily related to next generation sequencing and evolution through the network Bioinformatics Infrastructure for Life Sciences (NBIS) and I am active in the workshop on Genomics. I am a member of the steering committee in the Geneco research school that forges links between evolution, ecology and genomics.
