About me

I am a statistician by training and by heart. My aim is to learn as much as
possible about statistics. My main interest is deep philosophical questions,
such as how to draw conclusion about the world based on our observations.
Previously, I have worked at Astra and Statistics Sweden, where the data are
well designed and monitored. Now, here at KI, I work with data from
administrative registers, which are not quite at the same level.
Master of Science in Statistics
