About the Authors

Helen Sharp

Helen Sharp is a Professor of Software Engineering and Associate Dean in the Faculty of Science, Technology, Engineering, and Mathematics at the Open University. Originally trained as a software engineer, it was by watching the frustration of users and the clever "workarounds" they developed that inspired her to investigate HCI, user-centered design, and the other related disciplines that now underpin the field of interaction design. Her research focuses on the study of professional software practice and the effect of human and social aspects on software development, leveraging her expertise in the intersection between interaction design and software engineering and working closely with practitioners to support practical impact. She is active in both the software engineering and CHI communities, and she has had a long association with practitioner-related conferences. Helen is on the editorial board of several software engineering journals, and she is a regular invited speaker at academic and practitioner venues.

Yvonne Rogers

Yvonne Rogers is the Director of the Interaction Centre at University College London, a Professor of Interaction Design, and a deputy head of department for Computer Science. She is internationally renowned for her work in HCI and ubiquitous computing and, in particular, for her pioneering approach to innovation and ubiquitous learning. Yvonne is widely published, and she is the author of two recent books: Research in the Wild (2017, co-authored with Paul Marshall) and The Secrets of Creative People (2014). She is also a regular keynote speaker at computing and HCI conferences worldwide. Former positions include Professor of Interaction Design at the Open University (2006–2011), Professor of Human-Computer Interaction at the School of Informatics and Computing at Indiana University (2003–2006), and Professor in the former School of Cognitive and Computing Sciences at Sussex University (1992–2003). She has also been a Visiting Professor at UCSC, University of Cape Town, Melbourne University, Stanford, Apple, Queensland University, and UCSD. She has been elected as a Fellow of the ACM, the British Computer Society, and the ACM’s CHI Academy.

Jennifer Preece

Jennifer Preece is Professor and Dean Emerita in the College of Information Studies—Maryland’s iSchool—at the University of Maryland. Jenny’s research focuses on the intersection of information, community, and technology. She is particularly interested in community participation online and offline. She has researched ways to support empathy and social support online, patterns of online participation, reasons for not participating (for example, lurking and infrequent participation), strategies for supporting online communication, development of norms, and the attributes of successful technology-supported communities. Currently, Jenny focuses on how technology can be used to educate and motivate citizens to engage and contribute quality data to citizen science projects. This research contributes to the broader need for the collection of data about the world’s flora and fauna at a time when many species are in rapid decline due to habitat loss, pollution, and climate change. She was author of one of the first books on online communities—Online Communities: Designing Usability, Supporting Sociability (2000) published by John Wiley & Sons Ltd and several other HCI texts. Jenny is also widely published, a regular keynote speaker, and a member of the ACM’s CHI Academy.
