Biography
I am a Professor of Sociology and Computational Social Sciences at the Ludwig Maximilian University of Munich. My work focuses on applying computational methods to interdisciplinary research in areas such as ethnic minority & gender studies, social media, political communication, and sociotechnical systems. I am particularly interested in methods related to data mining, artificial intelligence, and multimodal data analysis.
Results of my work have been published in journals such as Computers in Human Behavior, European Sociological Review, Sociology, Social Media + Society, and Big Data & Society.
In addition to research, I have held courses and workshops on Data Analysis, Data Mining, Text Analysis, Network Analysis, and Political Sociology at several universities and institutes in Amsterdam, Bamberg, Berlin, Konstanz, Munich, and Stuttgart.
