I am faculty (W3, tenured) at the CISPA Helmholtz Center for Information Security, where I lead the research group on Exploratory Data Analysis. I'm Honorary Professor of Computer Science at Saarland University and ELLIS Faculty of the Saarbrücken Unit on Artificial Intelligence and Machine Learning.

My research is concerned with causality and unsupervised learning. In particular, I enjoy developing theory and algorithms for answering fundamentally exploratory questions, such as 'what is going on in my data?', 'what causes what and how?', 'what can we learn from this model?' without having to make unnecessary or unjustified assumptions. To identify what is worth knowing, I like to take a principled approach, such as based on information theory, and then proceed to develop efficient algorithms for extracting useful interpretable results. I like all data types equally much.

I am interested in causal inference under realistic conditions, such as e.g. under hidden confounding or selection bias, when the i.i.d. assumption does not hold, or while making use of background knowledge. I am always interested in how to summarize the essence of complex data and models in easily understandable and actionable terms, and using these to obtain better, more robust, and more useful models. I find the combination of these two threads especially exciting.
