Biography

I am a Biomedical Data Scientist currently working as Senior Bioinformatician at the cancer diagnostics company SAGA Diagnostics. Additionally I conduct research in affiliation with Lund University in Sweden.

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

Over the past 20 years I have contributed to a number of open source software projects, most notably the FreeBSD computer operating system. A rough overview can be found on OpenHub.
