I write columns and opinions pieces for various outlets. The majority of these - including those for Dutch newspaper De Volkskrant and local newspaper UKrant - are in Dutch, others in English. Please note that I use DMY as date notation (just as the vast majority of human beings).
Since January 2019 I write a monthly column on statistics and science for Dutch national newspaper De Volkskrant.
I write columns (in Dutch) for the University newspaper in Groningen, Ukrant.
The Dutch New Mathematical Archives publish on topics of interest for all types of mathematicians: scholars, teachers, people working in industry and hobbyists. I write columns for this magazine, sometimes in Dutch, sometimes in English.
All other columns, blog posts, etc.
