I am an Assistant Professor in Political Science at Leiden University, the Netherlands. Previously, I worked at Trinity College Dublin, Ireland, as an Assistant Professor. I obtained my Master's and PhD degree from Leiden University.

My main areas of interest include political representation, parliaments, political parties, elections, polls and voting advice applications.

In 2011 I defended my PhD thesis on the democratic mandate of political parties in Great Britain and the Netherlands.

I am teaching in the field of comparative politics, research methods and statistics. My undergraduate teaching materials can be found on Blackboard.

Blogs & Opinion Poll Aggregation
I regularly contribute to the political science weblog StukRoodVlees.nl. The Dutch public broadcaster NOS publishes my  my aggregation of Dutch national opinion polls, called 'Peilingwijzer' (Polling Indicator). My Irish Polling Indicator, is published regularly on politicalreform.ie.

Can you take polls seriously? My recent talk for the University of the Netherlands
