Dr Nicolas Rennuy
BA (Ghent), MA (Ghent), LLM (Cantab), PhD (Ghent)


I joined York Law School in September 2016. Previously, I was a Fellow and Lecturer at Murray Edwards College, Cambridge (2015–2016) and a PhD Fellow of the Research Foundation Flanders at Ghent University (2011–2015).

I am also an Analytical Expert on free movement and EU social security law for MoveS, an EU-wide academic network funded by the European Commission.



My research focuses on the interface between the free movement of persons and welfare benefits. Much of my work seeks to further the understanding and evaluation of EU social security law by drawing links with neighbouring fields and debates, such as private international law or EU administrative law. I’m currently working on social dumping and on social security coordination after Brexit. Very broadly, I’m interested in how law, created in and for a domestic context, works in cases that have ties to more than one legal order.

I’d be happy to discuss projects with prospective PhD students, especially in the following fields:

  • EU social security law
  • Free movement of persons and EU citizenship
  • Private international law
  • Transnational law
