Hi, I'm Hendrik! I'm a researcher at the
Institute for Analytical Sociology (IAS)
at Linköping University, Sweden.
I study 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. Find out at which conferences I'll be this year, and see my blog for bits and pieces on everything academic.

Published October 27th, 2025
Abstract: Sometimes, we all get hung up on fringe phenomena that are largely inconsequential for the world's pressing issues, but still satisfy some urge to understand within us. One such thing for me were monads, a weird little concept from group theory that sits at the heart of many programming jokes. I have spent years trying to understand them, and now that I finally did, I had to realize that I will probably never need them.
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.
