Tomas Johansson, Associate Professor

I’m an associate professor (docent) in microbial ecology since 2006. I got my PhD in biochemistry at the Lund University on biochemical studies of ligninolytic enzyme systems of white-rot fungi. This was followed by a 2-year postdoctoral stay in the Daniel Cullen laboratory at the Forest Product Laboratory (USDA) in Madison (U.S.), investigating heterologous expression of ligninolytic peroxidases in Aspergillus.

Presently my primary interest is fungal-plant interactions and specifically ectomycorrhizal (ECM) interactions. Our goal is to understand the molecular background of both the symbiotic and the saprophytic lifestyles of these fungi. Research is including both genomic and transcriptional investigations using different platforms such as next generation sequencing (NGS) and microarray analyses. For these purposes we are running a 454/Roche sequencing facility which is also providing public services.

My teaching is on various courses, both on under graduate and graduate level. For some time the department is running a national research school in genomic ecology (GENECO) in which I’m teaching genomics and global transcriptional analyses.
