Hello, and welcome to my homepage.

About me

I am an assistant professor of Information Systems at the Johannes Gutenberg-University of Mainz. I obtained my PhD from the University of Mannheim.

My main research interest is analytics with a  focus on social commerce, causal inference in big datasets (digital experimentation), machine learning, and social and information networks. I am also designing and analyzing computational intelligence for solving complex optimization problems in logistics and supply chain management. I teach an introductory course on social and information networks, an introduction to artificial intelligence, a doctoral course on metaheuristics and optimization and other introductory and advanced courses in Information Systems, e.g. introductions to electronic business or to the management of Information Technology.

I maintain a blog about IS, Big Data and Social Networks where I collect cool stuff that may be of interest to my students.
