Matti Nelimarkka is a researcher at Aalto University, Finland. His research interests include supporting participation and democracy via technology and interaction of politics and technology. He combines social research with digital, computational and design methods. In the context of this workshop, his previous work have focused to understand the social practices of hybrid events.

Antti Salovaara is an adjunct professor at University of Helsinki, Finland. He studies repurposive appropriation – the processes by which users discover new purposes of use for technologies. This research theme is relevant to also this workshop, since by being interactive open-ended tools, participation technologies offer many opportunities for appropriation.

Giulio Jacucci is Professor at the Department of Computer Science and the University of Helsinki. He has been Professor at the Aalto University, Department of Design 2009-2010. His research field and competencies are in human-computer interaction including mediated social interaction, information seeking and discovery, multimodal and implicit interaction, haptics and tangible computing, mixed reality, and persuasive technologies. He is also co-founder and member of the board of directors of Ltd. providing visual collaboration environments through modular screens.

Steven Dow is an Assistant Professor in the Department of Cognitive Science at UC San Diego where he researches human-computer interaction, social computing, and creativity. He received the National Science Foundation CAREER Award in 2015 for research on “advancing collective innovation.” He was co-PI on three other National Science Foundation grants, a Google Faculty Grant, Stanford’s Postdoctoral Research Award, and the Hasso Plattner Design Thinking Research Grant. Before UCSD, he was an Assistant Professor of Human-Computer Interaction at Carnegie Mellon University and a postdoctoral scholar in Computer Science at Stanford University.

Joel Fischer is an Assistant Professor at the School of Computer Science, University of Nottingham, UK, and a member of the Mixed Reality Lab. His research interest is in computational methods to support human activities and reasoning in collaborative settings. He is particularly interested in how interactive technology can be designed to support, (or disrupt) collocated people interacting face-to-face. His research approach is multidisciplinary, drawing on ethnomethodology, participatory design, prototyping, and studies of technology deployments.

Louise Barkhuus is an Associate Professor at the IT University of Copenhagen, Denmark. Her research focuses on location-based technology-mediated experiences, particularly interactive performance experiences. Her area of research also spans issues around social media, such as how social media can support off-line socialization and how location can be used as material for designing social experiences with attention to issues of privacy. Before joining ITU in 2016, she was a visiting professor at Cornell Tech University in NY and before that she held research and faculty positions at Stockholm University and University of California, San Diego.

Kenton O’Hara works in the Human Experience and Design Group at Microsoft Research Cambridge and is also a Visiting Professor in the Computer Science Department at the University of Bristol. His research explores everyday social and collaborative practices with technology with a view to informing design and innovation.
