Hello, I'm Dominik. I'm a postdoctoral researcher hosted by Ariel Procaccia at Harvard University.
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 at CMU's Computer Science Department (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: 2020-09-16 News. I have won the 2019 EurAI Distinguished Dissertation Award! I have moved from CMU to Harvard. While we're all working remotely, I've decided to do some travelling, so you won't find me in Cambridge, MA, for now. Currently, I'm in Grand Junction, CO. We have a new working paper out that introduces an attractive voting rule for participatory budgeting; I recommend reading the extended introduction.
