Prof. Dr. Tiziana Catarci
Database & User Interface Group, Universita' degli Studi di Roma "La Sapienza", Italy
Tiziana Catarci’s main research interests are in theoretical and application-oriented aspects of visual formalisms for databases and database design. With respect to theory, she has studied problems related to the formalization and evaluation of the expressive power of visual query languages. Moreover, she has worked on semantic database modeling, cooperative information systems, and statistical databases. On these topics she has published more than 100 articles in leading journals and conferences and 10 books. With respect to applications, she has led or participated in various projects on visual query systems and developed methodologies for database design, particularly related to translations between conceptual and logical schemas, and to data distribution. Outside of academia, she has been a consultant to large (private and government) organizations.

Dr. Nahum Gershon
The MITRE Corporation, McLean, VA
Nahum grew up in a melting pot – a real one. This multi-lingual environment was cerebral but also literal and oral. So naturally, he desired, since he was a child, to be a scientist, an aspiration he fulfilled specializing in the areas of chemistry, physics, and biology. Later in life, he discovered that humans cannot live on reason & linear thinking alone, so he went through years of personal transformation. Today, Nahum works on combining creative expressions like storytelling, film, and visual and interactive design with technology and strategic planning. He can still be logical (and very much so), but he does it only when appropriate. Nahum is a Senior Principal Scientist at the MITRE Corporation where he focuses on research and practical applications of presentation and visualization of data and information, as it relates to perception, society, storytelling, and culture. Routinely, he tries very hard not to torture his audience with PowerPoint slides and bully bullets whenever possible. In his free time, Nahum, among other things, participates in a number of national and international committees. He enjoys life.

Prof. Dr. Jim Parker
Digital Media Laboratory, University of Calgary
Jim Parker is currently Full Professor of computer science at the University of Calgary. He received his B.Sc. in Applied Mathematics and M.Sc. in Computer Science in calgary, and his Ph.D. (Doctor in de Wetenschappen) in Informatics (Informatica) from the State University of Gent (Universiteit Gent) with greatest distinction (met de grootste onderscheiding) or, in Latin, Magna Cum Laude. His Ph.D. thesis concerns pattern recognition in practical environments, and includes work on using vision methods to assist in water treatment plant control. Past research work involves discrete event simulation, pattern analysis, machine vision, and use of multiple/parallel algorithms. More recently the work involves multimedia, incorporating much of the past work into studies of video game technology. The specific interest is in Serious games, which is the use of games and game technology for purposes other than pure entertainment.

For over 40 years Bob Spence has pursued research in two fields, engineering design and human-computer interaction. A compilation of Bob's research in HCI up to around 1985, entitled Acquisition of Insight, was recognized by the award of a Higher Doctorate by the Royal College of Art. With colleagues, Bob has been responsible for a number of innovations including the Bifocal Display (now known as the Fisheye Lens), the Prosection Matrix and the Attribute, Influence and Neighbourhood Explorers. His book, Information Visualization (Addison-Wesley, 2001) has been widely adopted and forms the basis of many tutorials that Bob has given around the world. He is a Fellow of the IEEE and a Fellow of the Royal Academy of Engineering.
