Presentation

I am a senior scientific programmer in the Collective Information project of Ulle Endriss at the Institute for Logic, Language and Computation (ILLC) at the University of Amsterdam in (surprisingly) Amsterdam, The Netherlands.

Before that, I did my PhD under the supervision of Ulle Endriss, Jan Maly, and Ronald de Haan. My thesis titled Variations on Participatory Budgeting presents a wide range of approaches I used to analyse participatory budgeting.

The field I worked in is called as Computational Social Choice. The typical problems arising in (computational) social choice concern the aggregation of individual opinions into a collective, such as when people vote in an election. I studied different questions related to the aggregation of preferences, both from a mathematical and from a computational perspective.

I mostly focused on participatory budgeting, a democratic tool used to allow citizens to vote on how to allocation public funds. I have also worked on other topics such as the fair allocation of indivisible items, or how to handle incomplete preferences. I developed several tools during my time as a researcher: I am the main developer and maintainer of PrefLib.org, the PaBuTools, among others.

If you have no idea what social choice scientists do, the following video will offer you a glimpse at the typical problems we study when it comes to participatory budgeting.

Note that I am currently shifting towards a different direction and thus am not looking to start new collaborations. If you want to chat still, drop me an email at s.rey@uva.nl.
