Welcome to my website! This site is intended to provide some information on my professional activities. I am an applied statistician, epidemiologist, and demographer with a special interest in advanced statistical methods for counterfactual causal inference.
As of November 2015, I am employed at the Population Health laboratory of the Max Planck Institute for Demographic Research (MPIDR). At the MPIDR, I am primarily concerned with applying causal inference methods to study population health and mortality, but lately I have also been making some forays into fertility research.
In May 2018 I developed a workshop on Causal Mediation Analysis with Longitudinal Data. I taught this workshop for the first time at the University of Helsinki, Finland, in May. This went really well! Students especially praised the clear course material (annotated R-code) and teaching style. The workshop will be given again at the University of Helsinki, May 6th to 10th, 2019.
By popular demand, for the non-Dutch/Frisian. Using English orthography, the Frisian pronunciation of ‘Bijlsma’ is exactly like ‘Beel-sma’ (where ee is like in beet, and the sma like in smathering), and the Dutch pronunciation can be approximated by ‘Bell-sma’.
