Mathias is a full professor (W3) at the University of Stuttgart and a faculty member of the International Max Planck Research School for Intelligent Systems (IMPRS-IS). He heads the Machine Learning and Simulation Lab. His professorship is part of the Cluster of Excellence for the Simulation Sciences (SimTech), the Department of Computer Science, and the ELLIS society. He is also a Chief Scientific Advisor at NEC Laboratories Europe. At NEC Labs Europe he was senior (2015-2017) and chief research scientist (2017-2021) as well as manager (2019-2021) of the machine learning group. From 2013-2015 he was a postdoctoral research associate at the Allen School of Computer Science, University of Washington. Mathias was also a member of the Data and Web Science Research Group at the University of Mannheim. Mathias obtained his PhD from Indiana University in computer science with a minor in scientific computing.

His group's research interests include representation learning for structured data, geometric deep learning, probabilistic graphical models, and the intersection of ML and the sciences. His group's methods are concerned with learning, inducing, and leveraging relational structure with applications in vision, natural language processing, and the (bio-)medical domain. Mathias is also co-founder of several open-source digital humanities projects such as the Indiana Philosophy Ontology Project.
