Hi, I'm Hendrik! I'm a PhD Student at the
Institute for Analytical Sociology (IAS)
at Linköping University, Sweden.
My research revolves around legislative debates, how elected officials
talk with each other in parliaments, and how this relates to their voting
behavior. I analyze mechanisms of policymaking and how political regimes
change based on what issues politicians talk about and vote on. To do so,
I approach the large parliamentary corpora such as the Congressional Record
using large-scale text analysis.

In my dissertation, I focus on policymaking in U.S. Congress. I explore both the Congressional discourse and the voting behavior of representatives to understand how individual-level interactions between representatives work together, influenced by institutional context, to produce the policy we observe. I use computational text analysis tools, such as topic models, word embeddings, and BERT-models to explore the link between speech and voting behavior across a century of Congressional speech (1873–2011).
Academic Research
I am affiliated with the Institute for Analytical Sociology (IAS), Linköping University, Sweden. My research intersects with political and economic sociology, text analysis and computational social science.

Abstract: In this second reflection article on my dissertation, I talk about theory. I explore my theoretical origins, why I am no longer a theory guy, and how the PhD journey over the past five years have changed the way I approach and write theory. I reflect on the style of theory, and why it needs to differ between theoretically-heavy and methodologically-heavy papers, as both parts need to match each other.
Open Source development
When I'm not analyzing policymaking and individual behavior in parliaments, 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.
