I am a tenured lecturer/researcher at the University of Groningen, Institute of Artificial Intelligence and Cognitive Engineering (ALICE), Faculty of Mathematics and Natural Sciences, where I participate in the Multi-agent systems research program.

In the academic year 2013-2014, I was resident fellow at Stanford University. I participated in CodeX - the Stanford Center for Legal Informatics, a collaboration between the Stanford AI Lab and Stanford Law School, where I am now listed as affiliated faculty.

I have an MSc degree in Mathematics (University of Amsterdam, algebraic geometry) and obtained my PhD degree at Maastricht University (Faculty of Law, Department of Metajuridica; Faculty of General Sciences, Department of Computer Science), on a dissertation about the formal modeling of argumentation, with applications in law.

My research focuses on artificial intelligence, argumentation and law. I currently lead a research project on the connections between arguments, scenarios and probabilities in forensic reasoning with evidence, funded by the NWO Forensic Science program (2012-2016). Inspired by the interdisciplinary and cross-methodological insights gained in this project, I am working on the connections between knowledge, data and inference.

I am co-editor-in-chief of the journal Argument and Computation, section editor of the journal Artificial Intelligence and Law, and board member of several professional societies (BNVKI; COMMA; IAAIL, vice-president; JURIX, vice-president/secretary).

In 2014, I co-organized the event Trial With and Without Mathematics at Stanford University. In 2013, I was an invited visiting lecturer at the Institute of Logic and Cognition, Sun Yat-Sen University (Guangzhou, China). I served as program chair of the Fourteenth International Conference on Artificial Intelligence and Law (ICAIL 2013, Rome) and of the Fourth International Conference on Computational Models of Argument (COMMA 2012, Vienna). I am a member of the executive committee of the International Association for Artificial Intelligence and Law (IAAIL) and of the steering committee of the international conference series on Computational Models of Argument (COMMA).

A tag cloud that gives an impression of my research topics appears on the blog-style version of my publications page (there is also a CV-style version).

A semi-formal impression of my perspective on AI & law is available in this 2005 interview (in Dutch; pdf) or this 2007 coffeehouse conversation (inspired by Douglas Hofstadter's).
