My research in political theory deals with conceptualisations of democratic legitimacy. I particularly focus on deliberative democracy and consider the role of society-wide argumentative exchanges for democratic quality. These theoretical enquiries are complemented by empirical studies that measure political systems' deliberative quality and assess the impacts and contributions of deliberation in democratic policy-making.
Theoretical and empirical research should complement each other and normative theorising must do justice to ever changing societal contexts. Determining the precise relationship of theoretical and empirical findings poses serious challenges. I am applying philosophy of science-concepts to address these challenges.

Measurement of deliberative quality
Critical theory with a focus on Jürgen Habermas
Political philosophy of liberalism, Kantianism, and proceduralism
Digitalization-induced challenges for democratic societies
Democratic deliberation is not only relevant for democratic theorists. Increasingly, measures of democracy try to integrate this fluid and emergent phenomenon and attempt to examine the deliberative performance of states. Up until now, there is no comprehensive approach that measures not only the quality within deliberative fora, but also the connection between them and their integration in the political system as a whole.
Based on conceptualisations of systemic deliberative theory (Habermas, Dryzek, Mansbridge), the research project fills this gap and combines deliberative theory and the measurement of deliberation to develop an instrument for assessing and comparing nation states’ deliberative quality.
