julius diener

Welcome

Hello, my name is Julius and since summer 2023 I am a PhD student in Political Science at the University of Mannheim. I currently work as a researcher at the Mannheim Centre for European Social Research (MZES) and am affiliated with the Chair of Comparative Government held by Prof. Marc Debus. Starting in January 2026 I am also Managing Editor for the journal Politische Vierteljahresschrift / German Political Science Quarterly.

Substantively, my research interests are the representation and public opinion of social groups, especially young people and migrant origin individuals, in combination with party competition and parliamentary behaviour. Methodologically, I utilize a range of quantitative methods and various techniques from the computational text analysis toolkit.

My dissertation is supervised by Prof. Marc Debus (Mannheim) and Prof. Stefanie Bailer (Basel). In it, I study the political representation of young voters across Europe and investigate the role that different political elites play in this process. 

At the MZES I work in the project titled “Ethnic and Socio-Economic Background of Candidates for Political Office: Implications for Representation Patterns in Post-Migration Society”, led by Prof. Marc Debus. In this project, we study the political careers, attitudes and representation behaviour of politicians with diverse migrant background in Germany.

Before that, I have worked as a researcher at the Chair of Comparative Government. In this role, I have instructed several substantial and methods courses, also supervising a range of papers and BA theses. For my teaching, I have been awarded the CDSS Teaching Award 2025 for my seminar “Democratic Representation in Parliament”.

My work has been published in journals such as Politische Vierteljahresschrift / German Political Science Quarterly, Party Politics and Research & Politics.

My full CV can be found here, a full list of publications is here and my current work in progress is listed here.
