I am working in the field of Computational Social Science and leader of the GESIS team "Designed Digital Data". My research focuses on applying computational methods for ethnic minority & gender studies, digital media, political communication, and sociotechnical systems. I am particularly interested in methods related to natural language processing, image recognition, and data mining.

Results of my work have been published in journals such as Computers in Human Behavior, European Sociological Review, Social Media + Society, European Journal of Political Research, and West European Politics.

In addition to research, I taught courses about Data Analysis, Data Mining, Quantitative Text Analysis, and Political Sociology at the University of Bamberg, University of Konstanz, Humboldt University of Berlin, and the University of Stuttgart.

You can find more information such as my CV and latest publications on my website:
