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.
Updated: 2021-06-25 News. I have moved to the University of Toronto to do a postdoc with Nisarg Shah. CNRS has offered me a permanent research position at LAMSADE in Paris, that I will take up in February 2022.
