Prof. Matthias Grabmair, Ph.D., LL.M.

Matthias Grabmair is a tenure-track Assistant Professor of Legal Tech in the Department of Informatics at the Technical University of Munich. Before joining TUM in January 2021, he worked as a Legal Data Scientist at the German legal informatics company SINC (2019-2020). Prior to that, he spent four years at Carnegie Mellon University's Language Technologies Institute working with Prof. Eric Nyberg as a Visiting Researcher, Postdoc, and Systems Scientist (2015-2019). He obtained a diploma in law from the University of Augsburg, Germany, as well as a Master of Laws (LL.M.) and Ph.D. in Intelligent Systems mentored by Prof. Kevin Ashley from the University of Pittsburgh.

Dr. Grabmair serves as the section editor for Machine Learning of the Journal of Artificial Intelligence & Law and co-founded the ASAIL Workshop Series on Automated Extraction of Semantic Information in Legal Text, for which he has also been chairing the organizing committee since 2019.
