Instructors

Jonathan Liebers obtained a bachelor’s and master’s degree in computer science at the University of Duisburg-Essen. He currently is a Ph.D. student at the Human-Computer Interaction Group, University of Duisburg-Essen and his research interest lies mainly within the field of usable security and implicit identification, particularly XR [7–9].

Uwe Gruenefeld is a postdoc researcher in human-computer interaction at the University of Duisburg-Essen, Germany. During his fellowship-funded Ph.D. at the University of Oldenburg, he focused on AR and VR technology. After his Ph.D., his research centered around cross-reality systems, usable security, and privacy. Uwe has been a tutorial and workshop chair for different conferences and organized various tutorials and workshops. He co-authored various publications within the field of usable security [1, 7–9, 11].

Daniel Buschek leads a research group at the University of Bayreuth, Germany. In his research, he combines HCI and AI to create user interfaces that enable people to use digital technology in more effective, efficient, expressive, explainable, and secure ways. His published research includes work on behavioral biometrics for mobile devices and VR. He has given a course on Intelligent User Interfaces at CHI’21 [13].

Florian Alt is a professor for Usable Security and Privacy at the Research Institute CODE (University of the Bundeswehr, Munich). Florian looks at the role of humans in security-critical systems, focusing on topics related to behavioral biometrics, physiological security, and usable security in novel application areas, such as smart homes and VR. Florian was a subcommittee chair for CHI’20 and CHI’21. He has previously run workshops and courses in CHI’21 [12].

Stefan Schneegass is an assistant professor of human-computer interaction at the University of Duisburg-Essen. His research interests include the crossroads of HCI and ubiquitous computing, particularly the development of implicit authentication mechanisms. Schneegass received a Ph.D. in computer science from the University of Stuttgart, Germany.
