Welcome

I am a political scientist at the University of Konstanz in Germany (postdoctoral fellow at the Zukunftskolleg and independent researcher at the Department of Politics and Public Administration). In Konstanz, I am heading the project group on "Advances in Discourse Network Analysis". I am also a postdoctoral researcher at the Swiss Federal Institute of Aquatic Science and Technology (Eawag), which is located in Dübendorf close to Zurich and belongs to the ETH domain, and a member of the Policy Analysis and Environmental Governance (PEGO) group at the Institute of Political Science, University of Bern, Switzerland.

My research is mainly about political networks and computational politics, with applications in public policy and in European and American politics. I developed a Java-based software called Discourse Network Analyzer (DNA) in order to analyze policy debates or political discourse among relevant political actors in a dynamic way, drawing upon methods of social network analysis.

My current activities include the further development of the methodology of discourse network analysis, the application of (temporal and cross-sectional) exponential random graph models (ERGM) to research questions in political science, the implementation of TERGMs in a package called xergm for the statistical computing environment R, the development of an R package called texreg for the conversion of statistical model output in R to LaTeX and HTML tables, and the analysis of policy networks in the European (and particularly Swiss) water sector.

I regularly teach in the POLNET summer school or fall academy (registration open to external participants who want to learn network analysis). In 2013, I taught two methodological PhD seminars: "Introduction to the Statistical Computing Environment R" (Zeppelin University Graduate School, Friedrichshafen) and "Advanced Network Analysis: The Analysis of Cognitive Structures" (PhD Program Politics and Public Administration, University of Konstanz). In the spring semester 2014, I taught a PhD and MA seminar called "Introduction to Network Analysis" at the Zeppelin University Graduate School.

Please take a look at my publications, teaching and software pages to learn more.
