I am a postdoctoral researcher in the group of Martin Hoefer at RWTH Aachen University.
My research focuses on combinatorial optimization and algorithmic game theory, with particular interests in information design, approximation algorithms on graphs, and computational social choice.
Previously, I was a postdoctoral researcher at the Center for Mathematical Modeling (CMM) at the Universidad de Chile, hosted by José Correa. I received my PhD in September 2024 from the Technical University of Berlin, where I was advised by Max Klimm. Before that, I completed my Bachelor's and Master's degrees in Business Mathematics at the University of Cologne and worked as a student researcher under the supervision of Kevin Schewior.
