I supervise empirical social science theses that either fall into the area of quantitative methods or one of the following topics:

Political parties and organisations
Political communication (e.g. social media)
Elections and voting behaviour
Political ideology (populism,
extremism)
Parliaments
Comparative politics
Political systems (FRG, USA, etc)

What I do not supervise: Theory, history of ideas, interpretative methods,

Qualitative methods require a second supervisor who can advise you on this.

As a second supervisor, I supervise quantitative theses independently of the research topic.
