Profile
I work as assistant professor in Psychological Methods at the University of Amsterdam, where I research new (Bayesian) statistics and making them more accessible by writing software, tutorials, and textbooks. In my spare time, I like to gather data to statistically prove that I’m better at Mario kart and Terraforming Mars than my friends.
