About

I'm a statistician/data scientist/bioinformatician with roots in veterinary medicine and biology/ecology. I work with data from various fields of natural (e.g. genetics, ecology, biotechnology, medicine) and social sciences (e.g. official statistics, economy). Having fun with cloud solutions like AWS. My tool of choice is R, but I can also handle Python, HTML, CSS. Ask me about reproducible research and version control.

I feed many, many cats.
