Welcome to my site.

Currently, I am working as a Postdoctoral Researcher in the CRC/SFB 1342: "Global Dynamics of Social Policies" (Project A01) at the University of Bremen. Within the CRC I am involved in developing the Global Welfare State Information System WeSIS - an interactive, web-based information system on global dynamics of social policy. I hold a doctoral degree in Political Science from the University of Greifswald.

My research focuses on political parties, party ideology and party policy diffusion. More specifically, I am interested in ideological change of parties, its causes and consequences. In order to analyse change, one needs to locate parties first. For this reason, I am also interested in new ways of measuring "party ideology", in extending current databases on parties and in overcoming the "Western bias" still prevalent in party research. Methodologically, I am firmly rooted in comparative politics and macro-comparative analyses.

If you have any question regarding my work or the data collections, do not hesitate to get in touch. I look forward to your message!

Data Collection on Elections Global Finished

Elections Global - the "raw" data that served as the base for V-Party - is now available at Harvard Dataverse. It covers some smaller countries beyond V-Dem's scope and may therefore be of interest as well.
