Keynote Speakers

GI-Zeitgeist 2012 is delighted to announce Professors Sven Bertel and Gerard Heuvelink as keynote speakers for the event!


Sven Bertel is a junior professor at Bauhaus-Universität Weimar where he joined the Faculty of Media (Computer Science and Media Division) in April 2011 as chair of usability. Before moving to Weimar, he worked as a postdoctoral research associate at the University of Illinois at Urbana-Champaign, where he was dually affiliated with the Human Factors Division and the Beckman Institute for Advanced Science and Technology. Prior, Sven had been a researcher at Universität Bremen and the SFB/TR 8 Spatial Cognition. He holds a doctoral degree in informatics from Universität Bremen for a thesis in artificial intelligence / spatial cognition on Spatial structures and visual attention in diagrammatic reasoning (2009) and a diploma in informatics with minors in psychology and economics from Universität Hamburg (2001). Sven was a Fellow at the Hanse Institute of Advanced Studies, Delmenhorst, in 2010 and 2011, a visiting researcher at the University of California, Santa Barbara in 2004/05, and an Overseas Fellow at Indiana University, Bloomington in 1998/99.

In his research, Sven’s interests fall on various spatial cognition and spatial information topics with applications to human-computer interaction and information design. Current research themes include attention- / visual focus-based cognitive models and cognition-based heuristics for improving inter­­action quality in joint human-computer spatial reasoning and problem solving; cognition-based usability measures; the mental representation and processing of (visuo-) spatial knowledge, and useful computational models thereof; designing effective and efficient multimodal (spatial) information for specific user groups and educational contexts; spatial cognition in architectural design, and design support tools.


Gerard Heuvelink holds an MSc in Applied Mathematics of Twente Technical University (1987) and a PhD in Environmental Sciences of Utrecht University (1993). From 1991 to 2003 he was assistant professor in Geostatistics and Stochastic Simulation with the University of Amsterdam. Between 2003 and 2011 he worked as senior researcher in Geostatistics with Alterra. He is currently employed as associate professor in Geostatistics with the Department of Environmental Sciences of Wageningen University (since 2003) and senior researcher Pedometrics with ISRIC World Soil Information (since 2011). Dr. Heuvelink has written over 160 scientific publications on geostatistics, spatial uncertainty analysis and pedometrics, about 65 of which appeared in peer-reviewed international journals. He has been involved in many research projects dealing with spatial uncertainty in environmental modelling and spatial analysis and is worldwide recognized as a leading scientist in pedometrics and spatial uncertainty analysis, mainly through his publications  (notably his book Error Propagation in Environmental Modelling with GIS) and active involvement as Program Committee member in various GIS and accuracy-related conference series. Dr. Heuvelink chaired the Pedometrics commission of the International Union of Soil Sciences from 2003 to 2006 and was president of the Netherlands Soil Science Society from 2004 to 2007. He is associate editor of the European Journal of Soil Science and editorial board member of Geoderma, Environmental and Ecological Statistics, International Journal of Applied Earth Observation and Geoinformation and Geographical Analysis. He is member of the Board for Sciences of the Earth and Space of the Flanders Fund for Scientific Research.
