Academic Interests

Microbial dynamics and evolution. We are studying the sporeforming soilbacteria Bacillus cereus group (including also Bacillus anthracis and Bacillus thuringiensis) as a model system to gain knowledge about the adaptability, niche life and development. More than 80 genomes have been sequenced worldwide. Our studied include the analysis of multidrug efflux membrane proteins in these bacteria.

Teaching

Microbiology, molecular biology, immunology at the School of Pharmacy.

Responsible for the course FRM 1040.

Higher education and employment history

Professor in Microbiology at School of Pharmacy.

Prorector at University of Oslo 2002-2005.

PhD in Biochemistry at the Department of Medical Biology, University of Tromsø.

Honoraria

Elected member of the Norwegian Academy of Science and Letters (in 2011: Head of the Class of Science) and of the Norwegian Royal Academy of Science and Letters.
