Project leader in cancer informatics

Responsible for cross-group cancer informatics. Implementation of computational infrastructure and bioinformatics pipelines. Researcher in cancer heterogeneity, pan-cancer. Primarily research on prostate, colorectal, and ovarian cancers.


Education

2000: MSc in Mathematical modeling, Dept of Informatics, University of Oslo, Norway

Research interests

My current research interests involve analysis of different types of large scale genomic data from high-throughput methodologies:

- Algorithms for identification of mutations in solid cancers

- DNA/RNA sequencing analysis

- Cancer biomarker detection
