I joined the DDIS group at the Department of Informatics at UZH as a PhD student to continue my work on the news project Informfully. The main research goal of this project is to explore the normative and theoretical dimensions of diversity of political news recommendations, the algorithmic implementation, and the impact of such recommendations on society.
I have a BA in Philosophy and a MSc in Informatics. Before going to university, I worked as a software programmer and acquired a federal VET diploma in application development. I am honored to have received a scholarship of the Digital Society Initiative and to to be a part of the DSI Excellence Program.
