Hello, I'm Dominik. I'm a postdoctoral researcher hosted by Nisarg Shah at the University of Toronto. From early 2022, I will be a CNRS researcher at LAMSADE in Paris.
I work on computational social choice, studying voting rules and preference aggregation, and designing fair algorithms. Recently, I have been interested in how organisations can decide how to divide their budgets among competing projects. I also enjoy proving impossibility theorems in voting theory using computer-aided methods involving SAT solvers.
I was previously a postdoc hosted by Ariel Procaccia at Harvard University (2020–21) and at Carnegie Mellon University (2019–20). I did my PhD (DPhil, 2015–19) at the Department of Computer Science, University of Oxford, supervised by Edith Elkind, as a member of Balliol College. Previously (2011–15), I was an undergraduate student of Maths & Computer Science at St. John's College, Oxford. I'm originally from Barsbüttel, close to Hamburg.
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: 2021-12-07 News. Our paper Funding Public Projects: A Case for the Nash Product Rule (PDF) just received the Best Student Paper Award at WINE 2021! In February 2022, I will move to LAMSADE in Paris to start a permanent position with CNRS. I'm trying to brush up my French, but so far it is not going well.
