A picture of me I'm a postdoctoral researcher at GESIS – Leibniz Institute for the Social Sciences and Center for Advanced Internet Studies (CAIS). I am a member of the project SynDIKAT, a project funded by the German Ministry of Research, Technology, and Space, where I work as an expert in Social Science Research Methods, Natural Language Processing and Computational Text Analysis methods with a focus on social media disinformation and misinformation.

Most Recent Article: U.S. Midterm Elections: The Work Has Just Started

Published November 6th, 2026

Abstract: The Midterm Elections in the United States are over. And with it, there is much relief among democratic voters. However, despite the celebratory sense of victory that has swept the country earlier this week, now the actual work starts. The voters have given the Democratic Party a mandate, and now a two-year marathon will start with everything poised against the newly elected representatives. Time for an assessment.

Open Source development

In my spare time, I advocate for Open Source. Since at least 2006 I have been a user, supporter, and contributor to Free and Open Source Software (FOSS).

My main project is Zettlr. It is a "one-stop publication workbench" targeted at students and researchers in the arts and humanities. I started working on it in 2017 and have been the project lead ever since.

After the Twitter-exodus began, I started the go-to list for finding your peers, Academics on Mastodon. It lists hundreds of people from dozens of fields and Mastodon instances so that you can orient yourself in this new social media.

You can find more info on my involvement with software on my GitHub profile.
