I am a lecturer in the Intelligent Systems
Group of the computer science department
at Utrecht University, and professor in Legal Informatics and Legal Argumentation at the
Law Faculty of
the University of Groningen. I have master degrees in law (1985) and philosophy (1988)
from the University of Groningen.
In 1993 I obtained my PhD degree (cum laude) at the Free University Amsterdam
with a thesis titled Logical Tools for Modelling Legal
Argument. My main research interests concern computational models of argumentation and their application in multi-agent systems, legal reasoning and other areas. I am a past president of the International Association for AI & Law (IAAIL), of the JURIX Foundation for Legal Knowledge-Based Systems and of the steering committee of the COMMA conferences on Computational Models of Argument. I am on the editorial board of several journals, including Artificial Intelligence (from 2017 as an associate editor).
