Pepijn van Erp

Mathematician by education (Radboud University, Nijmegen, The Netherlands). I’ve worked as quantitative consultant for TNT Post (now PostNL) and spend some years in Tanzania. After returning to the Netherlands I have worked for the Nijmegen University Fund (not as a scientist). Currently looking for a part time job next to my other activities.

My main writing interests lie in science, bad science and pseudoscience. My articles are generally written in Dutch and that’s why I started this website. I think some of my articles might interest people without knowledge of this beautiful language and therefore I’ll present translations of some of those articles on this site. The longer articles are accessible via the top menu.

Since March 2012 I’m a board member of the Dutch sceptical foundation Skepsis. Most skeptical articles I wrote were published on, another website of Skepsis.

Probably I’ll write about other things as well on this website. Chess is a likely subject.
