About me

I was born in a small village in Noord-Holland (The Netherlands) and studied at Utrecht University, where I obtained my BSc and MSc in chemistry. During this time, I have worked mainly on colloidal synthesis, temperature-dependent luminescence, and spectroscopy. In 2019, I joined ARC CBBC as a PhD candidate in the group of prof. Bert Weckhuysen.

About my research

I mainly work on the application of luminescence thermometry for operando monitoring of oxidative coupling of methane. This is a potential approach for direct conversion of waste methane into ethylene, a widely used chemical building block. During this reaction, a lot of heat is generated, which can cause various problems. By introducing a small amount of luminescent material into the catalyst, I can use light to determine the temperature at the surface of the catalyst during reaction, to get more insight in the interplay between local temperature effects and the performance of the catalyst.
