Paul De Bra studied mathematics and computer science at the University of Antwerp, where he graduated with "greatest distinction" and obtained a teaching certificate in 1981. He received the PhD degree in computer science from the University of Antwerp in 1987. In 1988 and 1989, he researched WYSIWYG interfaces and document processing at AT&T Bell Laboratories in Murray Hill, New Jersey. In December 1989, he joined the Computer Science Department at the Eindhoven University of Technology, where he is currently a full professor and head of the Database and Hypermedia Research Group. From 1987 to 2007, he was also a part-time professor at the University of Antwerp in the Information Science Department and the Computer Science Department. Professor De Bra performs research on different aspects of hypermedia systems and object-oriented databases. Currently, he is most active in the area of adaptive hypermedia and adaptive Web-based systems with applications in technology-enhanced learning, e-culture, and e-commerce. He has been a reviewer and/or (associate) editor for several journals, including the ACM Transactions on Information Systems, Communications of the ACM, IEEE Multimedia, Data and Knowledge Engineering, Computers in Industry, the Journal of Digital Information, Interacting with Computers, the Journal on Web Engineering, the International Journal on Web Engineering Technology, The New Review of Hypermedia and Multimedia, and the IEEE Transactions on Learning Technologies. He has been a reviewer or program committee member of the following conferences: The World Wide Web Conference, the ACM Conference on Hypertext and Hypermedia, the International Conference on Adaptive Hypermedia and Adaptive Web-Based Systems, the AACE WebNet Conference, Advanced Visual Interfaces (AVI), and the (Dutch) Interdisciplinary Conference on Information Science.
Judy Kay is a professor of computer science at the School of Information Technologies (formerly the Basser Department of Computer Science) at the University of Sydney, Australia. She is a principal in the CHAI: Computer Human Adapted Interaction Research Group, leading research in advanced technologies for human computer interaction, supporting personalization, pervasive, and mobile interaction. Her vision is for it to support a highly personalized way for people to interact with the computers that they carry, those embedded within the environment, and desktop computers. She creates new tools for interaction in support of lifelong learning, collaboration, and personalized smart services. Examples of exploring novel interfaces for ubiquitous computing include new software for surface computing that enables people to interact at a table, new ways to access files when collaborating at a tabletop, and the Keep-in-Touch communication appliance. Her personalization research has created a framework for building personalized applications which enable the user to scrutinize and control the process of personalization. The core technologies are the Personis user modelling server and Personis-Lite. She has published extensively in conferences such as Pervasive, Computer Human Interaction (CHI), and User Modeling (UM, AH, UMAP), and in journals such as the IEEE Transactions on Knowledge and Data Engineering, the International Journal of Artificial Intelligence in Education, User Modeling and User-Adapted Interaction, Personal and Ubiquitous Computing, Communications of the ACM, and Computer Science Education. She has presented invited keynote addresses at UM 1994, IJCAI 1995, ICCE 1997, the International Conference on Computers in Education, ITS 2000, AH 2006, and ITS 2008.
Stephan Weibelzahl is a lecturer at the National College of Ireland and a course director of two postgraduate programs on learning technologies. His main expertise is in the evaluation of adaptive systems, exploring the use and impact of adaptivity. He has been the co-organizer of a number of international workshops in the area of personalization, including a workshop series on the evaluation of adaptive systems held at the User Modeling Conferences and Adaptive Hypermedia Conferences. He is also a reviewer/program committee member of numerous national and international workshops and conferences on related topics (e.g., AH, UM, and UMAP), as well as scientific journals (e.g., UMUAI, IEEE TLT, KI, and KER).
