I am a PhD-candidate in Computer Science working both at Leiden University and the Government of the Netherlands. My research is about applying network science in the infrastructure domain in collaboration with the Ministry of Infrastructure and Water Management. The ultimate goal is to assist inspectorates in their risk assessment in a data-driven way. This can aid in maximizing safety and minimizing environmental pollution with only limited inspection capacity.

I first obtained a bachelor’s degree in chemistry, but back then working with (substantial amounts of) data had already my interest. My masters is in analytical chemistry. In my MSc thesis I compared different analytical approaches to enforce sulphur emission regulation in international shipping, both from an instrumental and data science perspective.


Experience

PhD-Candidate

Leiden University & Ministery of Infrastructure and Water Management

My research focuses on data and network science in the governmental domain. My supervisors from Leiden University are Frank Takes, Cor Veenman and Jaap van den Herik and from the Ministery Jasper van Vliet. I am part of the IDlab team within the Human Environment and Transport Inspectorate.

2017 - Present

Mystery shopper

Freelance

Although completely different to my main occupation, I have now more than ten years experience in mystery shopping. I like to contribute to a better experience for the clients I work for. I successfully completed hundreds of projects, ranging from service checks for airliners, to hotels, shops, and restaurants checks. For these projects, I sometimes switch to a different personality to get a genuine customer journey. In the end, I draft an extensive report which can be used for corporate compliancy checks, employee training or legal compliancy checks.

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.
