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.
Since November 2015, I have been 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 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! The workshop will be given again at the University of Helsinki, in May 2019. Furthermore, in December 2019, I will be teaching an Introduction to Causal Inference course to students at the European Doctoral School for Demography, in Barcelona, Spain.
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’.
