Short Bio

I am a PhD student in the group of Prof. Brandt since February 2020. Before that, I studied Informatics at TUM, where I received my Bachelor's degree in 2018 and my Master's degree in 2020. My research focuses on decision making in groups, in particular on how to avoid manipulability in elections.
