Jilles is Tenured Faculty at the CISPA Helmholtz Center for Information Security, where he leads the Exploratory Data Analysis group. In addition, he is affiliated as Senior Researcher with the Database and Information Systems group of the Max Planck Institute for Informatics, as well as Professor at the Department of Computer Science of Saarland University.

His research is mainly concerned with exploratory data mining and interpretable machine learning. That is, developing theory and algorithms for summarising data in easily understandable terms. To identify what you need to know, i.e., what is the most interesting structure in the data, he often employs information theoretic methods. In particular, the principles of Minimum Description Length (MDL) and Maximum Entropy have proven to be highly valuable tools.

Currently he is investigating techniques for identifying informative local structures in large collections of complex data; how to efficiently mine good data descriptions directly such data; how to mine very large graphs, including characterising influence propagation in social networks; and, last but not least, how to determine cause and effect, i.e. causal inference and modelling.
