Visualisation in research

Visualisation is key in any project involving datapoints. Yet the reader is not ‘showered in graphical displays’ [Anscombe, 1973]. I am an active promotor of the use of visualisation, and try to help people make graphs in several ways: i) by making the graphs for them; ii) by giving visualisation-workshops in R; iii) by creating R-packages that facilitate the use of graphs.

Studying the number of children people want and have

There is huge variation in the number of children people (would like to) have over time / across the globe / within countries. I try to study the determinants of this variation, including individual factors like wealth and education, genetic factors, and social influences.

Evolutionary perspectives on human height variation

My research in the past has focussed on variation in human height. In particular, how evolutionary processes have been and are shaping variation in stature. I tried to address questions like: Why is there such variation across countries in height? Why are women on average shorter than man? In what ways does height play a role in mate choice and competition? Does natural selection act on height in contemporary populations? Why are the Dutch so tall? Why am I so tall?

Given the upcoming US elections, several media outlets have shown interest in my research on US presidential height. So did The Economist: https://www.economist.com/graphic-detail/2020/02/19/in-politics-height-matters.

They definitely improved my graphs:

I should try and see if I can recreate those graphs in R.

Recentelijk werd ik geïnterviewd voor het Parool over het (jong) krijgen van kinderen: https://www.parool.nl/ps/tom-wordt-jong-vader-en-daar-heeft-iedereen-een-mening-over~b8f8e98a/. De auteur van het stuk, Tom Grosfeld (25) en zijn vriendin (26) verwachten hun eerste kind. Tom beschrijft mooi hoe zijn omgeving reageert. Zijn stuk sluit nauw aan bij mijn onderzoek over sociale invloeden op de kinderkeuze!
