About Me

I am a freelance Bioinformatician and Data Scientist providing consulting services to clients in industry and academia to help them make sense of their data. Previously, I lead the bioinformatics and data science team at SAGA Diagnostics, a company developing personalized cancer diagnostics based on genomics and liquid biopsy. Additionally, I conduct research in affiliation with Lund University in Sweden.

My main interest is in using computational methods and biological/medical data to improve our understanding and treatment of diseases. Many of my projects, including my doctoral thesis, have been focused on cancer in humans. 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 GitHub and OpenHub.
