Fabian Fischer is a disciplinary hybrid, combining Science & Technology Studies with Computer Science. He is currently University Assistant (prae doc) at the Centre for Informatics and Society (C!S) at the TU Wien. His research interest is the study of algorithmic systems, particularly those that are data-driven, with a focus on marginalisation practices. Strong technical skills gathered during several years in research & development of data-driven systems (largely in EU-funded research projects) is combined with strongly empirical, qualitative social science research. This interdisciplinary expertise is also the foundation of his teaching on Critical Algorithm Studies at TU Wien.
