About me

I have moved to TU Delft! You can find me here!


I studied Chemistry at Utrecht University (BSc & MSc) and received my PhD in Materials Science at ETH Zurich in 2015.

I'm interested in structural chemistry and crystallography, but my main research topic is on the development of methods for characterizing the structures of complex polycrystalline materials, with a particular focus on zeolites and other open framework materials.

Since the beginning of 2016 I work as a postdoc at Stockholm University. Here I'm developing a new method that brings the serial crystallography technique to the electron microscope, so that thousands of diffraction patterns can be collected automatically. I'm also developing software that controls the microscope and the camera to automate electron diffraction data collection, so that high quality data for structure refinement can be collected routinely. My favourite programming language is Python.
