Brygg Ullmer is Professor and Chair of the Human-Centered Computing (HCC) Division within the School of Computing at Clemson University, where he also leads the Tangible Visualization group. His research interests include tangible interfaces, computational genomics (and more broadly, interactive computational STEAM), visualization, and rapid physical and electronic prototyping. He also has a strong interest in computationally mediated art, craft, and design, rooted in the traditions and material expressions of specific regions and cultures. Ullmer hosted and co-chaired the inaugural ACM TEI 2007 conference; conference co-chair of TEI 2016; and is a steering committee member. Ullmer received M.S. and Ph.D. degrees from the MIT Media Laboratory, and a B.S. in computer engineering from the University of Illinois, Urbana-Champaign. Orit Shaer is Professor of Computer Science at Wellesley College. She directs the Wellesley College Human–Computer Interaction (HCI) Lab. Her research focuses on novel HCI for the future of work and learning. Dr Shaer is a Senior Member of the Association of Computing Machinery (ACM), and a recipient of several NSF and industry awards including the prestigious NSF CAREER Award, Agilent Technologies Research Award, and Google App Engine Education Award. At Wellesley she was awarded the Pinanski Prize for Excellent Teaching. Dr Shaer is a steering committee member of the ACM conference on Tangible Embedded and Embodied Interaction (TEI) and served as Program Chair in 2010, 2017, and most recently in 2020. Dr Shaer received M.S. and Ph.D. degrees from Tufts University in computer science. Ali Mazalek is Canada Research Chair in Digital Media and Innovation and Professor in the RTA School of Media at Toronto Metropolitan University (formerly Ryerson University), where she directs the Synaesthetic Media Lab. Her research investigates how tangible and embodied media can support and enhance creative practices and processes, supporting new forms of expression and new ways of thinking and learning. She is an Affiliate Scientist at the Keenan Research Centre for Biomedical Science, St. Michael's Hospital, and is a member of the Ryerson Institute for Biomedical Engineering, Science and Technology (iBEST). She was a member of the inaugural cohort of the Royal Society of Canada's College of New Scholars, Artists and Scientists. Mazalek is a steering committee member of the ACM TEI conference, and served as a Chair from 2013–2016. She was a Program Chair for the TEI conference in 2008 and 2015. Mazalek received M.S. and Ph.D. degrees from the MIT Media Lab and a Hon.B.Sc. in computer science and mathematics from the University of Toronto. Caroline Hummels is professor of Design and Theory for Transformative Qualities at the Department of Industrial Design at the Eindhoven University of Technology (TU/e). Over the past 25 years, she has worked at the forefront of design research pushing its boundaries, for example, by (co-) establishing the field of Research through Design, and jointly establishing ACMTEI, as program co-chair of the inaugural TEI 2007 conference, conference cochair of TEI 2016, next to being a steering committee member. With designing for transforming practices, she is taking with her colleagues, social, public, and private partners the next leap in design research: imagining and designing alternative practices for sustainable worlds in becoming driven by design philosophy correspondence. Embodied interaction, aesthetics, complexity, and technology-in-becoming play an important role in her work. Hummels received M.S. and Ph.D. degrees from Delft University of Technology in Industrial Design Engineering.
