About me

I am a PhD candidate in Applied Statistics in the Mathematical Institute at Leiden University. My PhD research focusses on optimal scaling for variables in models fitted with the maximum likelihood approach. So far, I have implemented the optimal scaling method in the survival analysis setting and for logistic regression. I collaborate with the Leiden University Medical Center and the Dutch Social Security Agency (Kenniscentrum UWV), which gives me access to some interesting datasets.
Furthermore, I am interested in statistics communication and will do do a research project in this field as part of my PhD project.
