I'm a PhD-candidate in Computer Science working both at Leiden University and the Government of the Netherlands. I first obtained a bachelor degree in Chemistry, but back then working with (large amounts of) data had already my interest. In Leiden, I focus on applying network science in the infrastructure domain in collaboration with the Ministry of Infrastructure and Water Management.

In general, I like to play sports (including korfball, volleyball, softball, skiing, snowboarding). And since very recently, we have a boat! We plan to explore the many waterways in the Netherlands, which we will cover in a blog in the very near future. When weather conditions (or corona crisis) don't allow me to do this, I work on my home automation set-up, which includes now over 30 devices.
