About me

I am a PhD candidate in Applied Statistics in the Mathematical Institute at Leiden University. My PhD research focusses on the analysis ordinal variables in models fitted with maximum likelihood. I have implemented optimal scaling and/or principal component analysis methods in the survival analysis setting and for logistic regression. I prefer to apply these models on simulated or real data to see the effect of the methods on data. 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 science communication and plan to do a research project in this field as part of my PhD project.
