Johannes Brinkrolf received his Master’s degree from Bielefeld University in 2016. From April 2016 to September 2016, he was a research assistant at the South Westphalia University of Applied Science. From October 2016 to July 2023, he was a Ph.D. student in the Machine Learning group at the Center for Cognitive Interaction Technology at Bielefeld University. In July 2023, he defended his thesis dealing with applications of learning vector quantization models. His research interests cover differential privacy, federated and distributed learning, foundations of machine learning, and prototype-based learning models. Since January 2023, he has been working as a member of the IT service of the Faculty of Technology.
