Brief Bio
Pawel W. Wozniak is Professor of Human Computer Interaction and Head of the Research Unit for Human Computer Interaction at TU Wien. Before joining TU Wien, he held academic positions at Chalmers University of Technology, Utrecht University, and the University of Stuttgart. He received his PhD in Human-Computer Interaction from Chalmers in 2016. His research explores the intersection of interactive technologies, sport, and wellbeing, with a particular interest in how people experience physical activity in everyday life. He studies personal informatics practices to understand how people collect, interpret, and reflect on data about their own activities, and how such practices can be better supported through design. Much of his work involves building and studying interactive prototypes, especially devices for sport and movement. Beyond this, his research spans multi-surface interaction, sensory augmentation, and the social and ethical boundaries of interactive technologies, including experiences that users perceive as unsettling or creepy. His work has received multiple paper awards at venues such as CHI, DIS, MobileHCI, and EICS. He has also served in several community roles, including General Chair of TEI 2023 and ISS 2021, and Chair of the SIGCHI Poland Chapter.
