Hello, I'm Dominik. I do research on decision making at LAMSADE, part of Université Paris Dauphine–PSL. I'm a CNRS chargé de recherche, which is a tenured research position.
I work on computational social choice, studying voting rules and preference aggregation, and designing fair algorithms. My main focus is on designing decision procedures that satisfy proportionality, where each voter has equal influence on the outcome. In particular, I'm interested in how organisations can decide how to divide their budgets among competing projects using proportional voting rules. I also enjoy proving impossibility theorems in voting theory using computer-aided methods involving SAT solvers.

On equalshares.net, we present the Method of Equal Shares for Participatory Budgeting. It is a fairer voting method to collectively decide how to use a common budget. The website explains the method and its benefits over other methods, and gives detailed discussions of how to implement it in practice. The website is available in English, German, and Polish.
Try out lpdual.com, a little website I've built that helps you derive LP duals, variants of Farkas' lemma, and KKT conditions. Perfect if you just cannot remember whether the dual variable of an at-least constraint should be non-negative or non-positive!
Updated: 2023-03-16 News. I wrote a Wikipedia page with a list of cities using participatory budgeting. We have recently published equalshares.net, a website explaining our proposals for a voting rule for participatory budgeting. See also the improved version of our NeurIPS'21 paper about this method. In July 2023, I will be giving lectures on fair division, distortion, and multi-winner voting at the COMSOC summer school in Amsterdam.
