Group Members

Jilles is the leader of the Independent Research Group on Exploratory Data Analysis at the DFG Cluster of Excellence on Multimodal Computing and Interaction at Saarland University. In addition, he is affiliated as Senior Researcher with the Database and Information Systems group of the Max Planck Institute for Informatics.

His research is mainly concerned with exploratory data mining. 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.

Mario is a post-doctoral researcher affiliated with the Exploratory Data Analysis group, the Theory department at the Fritz-Haber Institute in Berlin, as well as with the Knowledge Discovery department of Frauenhofer IAIS in Sankt Augustin.

His research activities can be characterized, on the one hand, by the quest for a sound theoretical understanding of research questions, and, on the other hand, by the practical application of research results to real-world problems. Therefore, he continuously pursues the integration of theoretical insights into robust and reusable software artifacts.

He currently works on the Novel Material Discovery (NoMaD) project, where we use data mining techniques such as subgroup discovery and correlation analysis to discover knowledge on why materials have certain properties.
