Research interests

2003 I started my doctoral thesis in the field of analysis of complex networks. Complex networks are a common way to model and analyze complex systems. Therefore, their results are often used to draw conclusions about complex systems - these results can also have political consequences. An eye-opening article was published by Professor Carter Butts in 2009 under the title "Revisiting the Foundations of Social Network Analysis". At that time, I had already designed several algorithms and conducted various interdisciplinary network analyses. I was particularly interested in the question why there are so often many measures for the same kind of question, e.g. about 60 measures to sort the nodes of a network according to their importance. In an article by Steve Borgatti, he explains that we shouldn't actually be investigating the structure of the (static) network, but the processes that run on it: On a (real) social network information can be transmitted, people infect each other with the latest flu or they support each other. Each of these flow processes requires different centrality measures. Borgatti thus linked the type of network flow (a social process) with the mathematical measure with which it can be investigated. Without knowledge of the social process, however, an interpretation of any centrality measure is not possible. I began to examine this problem in its generality: "When is which measure, which approach of network analysis appropriate to draw a conclusion about the real world? I have published my results in my book Network Analysis Literacy. Since then, we have extended the approach to data science in general and are working on various questions in the area of algorithm accountability. To reflect this in the naming of the group, in 2017 I renamed my group to the "Algorithm Accountability Lab". We are working on questions about measuring the quality and fairness of algorithmic decision systems (ADM systems), black box methods for monitoring ADM systems, theoretical questions about the robustness of machine learning methods, and we are also thinking about the best way to regulate ADM systems.

As a member of the Enquete Commission of Artificial Intelligence (2018-2020), a member of the ITA advisory board of the BMBF (since 2014), of the Plattform Lernende Systeme (AG3, UG Ethics and Law), I also carry our research into society.

I was also in charge of the course of studies in socioinformatics, which was accredited in 2013. In 2017 I was awarded the Ars legendi Faculty Prize in Engineering and Computer Science for the design of this unique course of studies in Germany.
