BSc, Dipl-Math, PhD
Dr Markus Brill has been a Fellow and Tutor in Computer Science at Oriel College since January 2026. He is also an Associate Professor in the Department of Computer Science.
He studied mathematics and computer science in Kaiserslautern, Zurich, and Munich, and obtained his PhD in Computer Science from TU Munich in 2012. He subsequently held postdoctoral positions at Duke University and the University of Oxford, before leading the research group “Foundations of Interactive Democracy” at TU Berlin (2017–2022), funded by the Emmy Noether Programme. From 2022 to 2025, he was an Associate Professor of Computer Science at the University of Warwick.
Markus’s research focuses on computational social choice — the study of algorithms for collective decision making, including voting rules and other methods for aggregating the preferences of multiple stakeholders. His work on proportional representation has established foundational concepts now widely adopted in the field, with applications in democratic innovation and AI safety.
