Marjolein Fokkema

Associate Professor
Leiden University


Marjolein works with Zino Brystowski, Mark de Rooij and Hilde Huizinga on how to best test and integrate different theories from multiple domains, in order to explain and predict how young people grow up and contribute to society.

Marjolein is an associate professor at the unit of Methodology and Statistics of Leiden University’s Institute of Psychology. She develops machine-learning algorithms that can deal with large amounts of data (‘big data’), but that provide results that are easy to understand, even by non-statisticians. She implements these algorithms in open-source software packages, and writes pop songs and produces music videos about them as “Mary-Jo & the Support Vector Machines”.
