Dominik Peters, selfie on train EC 9 near Bremen, April 2019

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 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: 2020-05-14 News. My publications are now ordered by year rather than by type. I've also added an option to filter by topic. Hope it makes the list easier to use! In August, I will move to Harvard. Several new working papers out, about participatory budgeting with voluntary contributions, about giving short axiomatic explanations of the Borda rule, and about two different interpretations of the notion of proportionality.
