Postdoctoral Research Assistant · AGH University of Krakow

I am a postdoctoral fellow at AGH University of Krakow, working with Piotr Faliszewski on the ERC-funded project PRAGMA. I received my PhD from the Czech Technical University in Prague, where I was part of the G²OAT research group supervised by Dušan Knop. My research explores how computational methods can make collective decisions like participatory budgeting, resource allocation, and coalition formation more fair and efficient. I combine theoretical tools from parameterized complexity and algorithmic game theory with experimental evaluation to understand when these problems are tractable in practice and to validate algorithmic solutions and mathematical models underlying these problems on realistic instances.
