Published (as an undergrad)
I co-authored a book on an assignment for the Dutch national student union (LSVb). I also edited its second and third editions. As of October 2016, it is in its fifth edition and is the standard handbook for student co-determination at universities and vocational learning institutions in the Netherlands.
The illustration on the front cover was made by gifted illustrator, philosophy graduate, and close friend Jorrit Kiel.
