I'm Professor of Artificial Intelligence and Collective Decision Making at the Institute for Logic, Language and Computation (ILLC) at the University of Amsterdam, where I lead the COMSOC Group. My research concerns the use of formal methods in AI, specifically in multiagent systems and knowledge representation. I'm particularly interested in problems at the interface of AI with economics and political science, and much of my work in this area falls under the heading of computational social choice.
Specific research topics in this domain I have contributed to include preference modelling, voting theory, judgment aggregation, fair division, negotiation, and auction design. I have also worked on agent communication languages, formal models of argumentation, automated reasoning, abduction, modal and temporal logics, and software tools for teaching logic.
I teach courses on Computational Social Choice and Game Theory for our MSc Logic and MSc AI programmes, as well as a course on Problem Solving and Search for the first-year students in our BSc AI programme. I feel a strong moral obligation to make all of the teaching materials I have developed over the years openly available to everyone who might be interested.
