Daniel A. Keim received the PhD degree in computer science from the University of Munich in 1994. He works in the area of information visualization and data mining. In the field of information visualization, he developed several novel techniques which use visualization technology for the purpose of exploring large databases. He has published extensively on information visualization and data mining; he is an editor of the IEEE Transactions on Visualization and Computer Graphics and the Information Visualization Journal. He has been with the Computer Science Department at the University of Munich, the Computer Science Department at the Martin-Luther-University Halle, and is a full professor in the Computer Science Department at the University of Constance. Recently, he worked at AT&T Labs, Florham Park, New Jersey. He is a member of the IEEE Computer Society.
Tamara Munzner received the PhD degree from Stanford University in 2000. She has been an assistant professor at the University of British Columbia Department of Computer Science since 2002. Her current research interests are information visualization, graph drawing, dimensionality reduction, and interactive computer graphics. She was a research scientist from 2000 to 2002 at the Compaq Systems Research Center in California. She was on the technical staff of The Geometry Center, a mathematical visualization research group at the University of Minnesota, from 1991 to 1995.
Stephen C. North received the PhD degree in computer science from Princeton University in 1986. He is head of Information Visualization Research at AT&T Labs, a group that studies novel interactive displays and high-performance graphics for network visualization in the AT&T Infolab. His background is in software visualization, applied computational geometry, and the design of reusable software. He is one of the authors of graphviz, a widely used collection of open source programs for drawing and interacting with graph layouts. His other current technical interests include dynamic and large scale graph visualization, spatial data transformation, and high-performance visualization systems. He is a senior member of the IEEE and a member of the ACM.
