I am a postdoc at the Algorithms and Complexity department at the Max Planck Institute for Informatics, currently visiting José Correa and Victor Verdugo in Chile. I obtained my PhD at the DISCO group at TU Berlin, where I was fortunate to be advised by Max Klimm and Felix Fischer. Previously, I graduated as an industrial engineer and MS in Operations Management at Universidad de Chile, being advised by José Correa and Victor Verdugo for my thesis.
My research interests lie in the intersection of economics and computation, especially in the fields of algorithmic game theory and social choice. I enjoy thinking about topics such as mechanism design without money and political apportionment using tools from discrete mathematics and optimization.
