Research Interests

My research focuses on the development of diagnostics based on tumor DNA/RNA deep sequencing (also known as next generation sequencing) to improve breast cancer treatment and survival. Most of my projects are embedded in the Sweden Cancerome Analysis Network–Breast (SCAN-B) study. Additionally I work on improving open source bioinformatics and reproducible research infrastructure by contributing to projects such as conda-forge, Bioconda and Biopython.
