Short Bio
From March 2021 to April 2025, I was a PhD student in the group of Professor Felix Brandt before graduating with a PhD in mathematics. I received my bachelor's and my master's degree also from the Technical University of Munich. My research interests comprise various topics from computational social choice and algorithmic game theory including dynamics and fairness notions.
My new website can be found here.
