I am a professor of bioinformatics leading the Research Group for Biomedical Informatics (BMI) at the Department of Informatics, University of Oslo. I am also affiliated with the new Centre for Bioinformatics. In addition, I work as a research scientist at the Department of Microbiology at Rikshospitalet, Oslo University Hospital (OUS).

Scientific interests

I work on problems in bioinformatics, in particular those related to analysis of DNA and protein sequences. Parallelisation of algorithms for sequence comparisons, searching and clustering of large databases are some of the things I've worked a lot with.

Through the position at the hospital, I've also worked quite a bit with applied bioinformatics, often related to characterisation of genes involved in DNA repair.

Recently, I have developed methods and tools for microbiome bioinformatics, where we analyse sequencing data from amplicon sequencing of rRNAs to determine the composition of microorganisms in samples.

Research projects

VSEARCH: Open and free 64-bit multithreaded tool for processing metagenomic sequences

SWIPE: Smith-Waterman database searches with inter-sequence SIMD parallelisation

SWARM: A robust and fast clustering method for amplicon-based studies

Publika: Publication database for Oslo University Hospital
