I’m a PhD researcher at the Information Retrieval Research Group of the University of Applied Sciences in Cologne. I’m part of the federal research training group on “digital society” (Graduiertenkolleg Digitale Gesellschaft).

My research focuses on the influence of web search engines on political opinion formation. I am interested in statistics, text mining, data visualization, databases and programming.
