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 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.
A few months ago 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.
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’. Bijlsma is a Frisian surname. A ‘Bijl’ is an axe, and ‘ma’ is believed to come from the Old Frisian monna (the genitive plural case of ‘man’) meaning ‘of the people’. Hence, I am Maarten of the People of the Axe (rest assured, I mostly wield statistics these days!).
