Dr Grammateia Kotsialou is a research scientist specialising in mechanism design, game theory and voting systems in the Department of Informatics, King's College London.

From September 2024, she is a Research Associate at King's College London on the EPSRC-funded project, "Driving Behaviour in Multi-Winner Elections and Participatory Budgeting," in collaboration with the University of Oxford's Department of Computer Science. Prior to this, she was an LSE Fellow in Mathematics within the Operations Research group at the London School of Economics and Political Science (LSE) from 2020 to 2024.

Previously, Dr Kotsialou was an Adjunct Lecturer in Operation Management at King's College London (2019-2020). Her initial postdoctoral role was also at King's, in the Political Economy Department, where she served as a Research Associate from 2017 to 2019 on the interdisciplinary project VOLT, which focused on creating trusted and transparent voting systems by exploring the potential of distributed ledger technology to enhance democratic processes.

Her core research interests include economic mechanism design, algorithmic game theory, and the use of AI for social good, with a particular interest in decentralisation. Her research has appeared in various academic journals and conference proceedings, reflecting her interdisciplinary interests, with notable contributions to liquid democracy, the application of blockchain technology to voting, data, and environmental markets, and cost-sharing mechanisms in congestion games. She holds a PhD in Economics and Computation from the University of Liverpool.
