I work for Stichting Proefjes, where I maintain the website Proefjes.nl, organize the activities of Proefjeslab, give teacher trainings, and advise primary schools.

I wrote the Proefjesboek, a children's book with do-it-yourself science experiments which was released by Uitgeverij Nieuwezijds in 2015. I also wrote some articles about doing science experiments.

I manage the mailing list of het woord van vandaag, a Dutch-English word of the day for non-native speakers who want to improve their vocabulary.

I publish typography photos for Amsterdam Typography and Netherlands Typography every day.

I've built several websites for my own projects and commissioned by others.
