Cornelius Erfort
I am a Postdoc at the Witten/Herdecke University, working on the project Election Forecasts for the German Federal Election 2025.
My general interests are in comparative politics and quantitative methods. More specifically, I am working on voter targeting, interest groups, and voting behavior.
In my dissertation, I analyzed how parties use the target and tailor their digital election ads. I was member of the Research Training Group DYNAMICS which is jointly organized by Humboldt-Universität zu Berlin and the Hertie School. During my PhD, I visited the LSE Department of Government for one term (2023). I completed my pre-doctoral studies at the Humboldt-Universität, spent a semester at the CIDE in Mexico City (2017) and have a background in mechanical engineering.
I have co-authored work with António Valentim, Jan Stuckatz, Felix Hartmann, Lukas F. Stoetzer, and Heike Klüver.
On this website, you can find more information on my research projects and download a copy of my CV (PDF).
