Welcome!

Welcome to my website! I am an applied statistician and (pharmaco)epidemiologist with a special interest in advanced statistical methods for counterfactual causal inference and an emerging interest in machine learning.

Recently, I decided to switch tracks and took up a position as Clinical Data Scientist at the Comprehensive Cancer Institute Netherlands (IKNL). In this new position, I will once again have more time to personally perform research that matters, while also being much closer to real world implementation of that research.

I continue my commitments to academic science as well, though! I retain an affiliation with the Groningen Research Institute of Pharmacy, University of Groningen, where I supervise PhD students Irene Mommers and Stefan Verweij on the topic of Precision Drug Therapy & Real World Evidence.  I also retain an affiliation with the Max Planck Institute for Demographic Research (MPIDR), where previously I was the Deputy Head of the Population Health laboratory. At MPIDR, I supervise the work of PhD student Maria Gueltzow, who studies mental health using advanced statistical methods.

Since I get asked questions about it: my surname comes from Frisian. If you don’t know how to pronounce it, following English orthography just say ‘Bell-sma’ or ‘Beel-sma’ (either way is fine).

Thanks!
