*Social Networks and Democracy*
How do social networks impact democracy? In the age of ‘fake news’, this question is societally more relevant than ever. This project develops a general theory of the interaction between networks and democracy, tests its results on the ‘liquid democracy’ voting system, and provides concrete recommendations that provably safeguard democracy.

NEWS (02-20): The Dutch Human Rights Institute ruled that the Erasmus University Rotterdam discrimated against me while I was pregnant because they did not reschedule my job interview planned when I was about to give birth.
