I am an Assistant Professor in the Department of Computer Science at Aarhus University, and a member of the Computational Complexity and Game Theory group. Before that, I was a postdoctoral researcher at École Polytechnique Fédérale de Lausanne and Singapore University of Technology and Design. I received my PhD from National Technical University of Athens in algorithmic game theory and theoretical computer science.

Research

My research focuses on the mathematical foundations of Game Theory, Machine Learning, and Optimization. I am particularly interested in understanding the collective behavior of machine learning algorithms in fundamental economic settings, such as auctions, markets, and traffic systems.
