During 1971-1976, he worked with his mentor Professor Hertz at the University of Lund. Together they invented the Color Graphics System based on the first ink jet plotter for raster based visualisation software in the world. In 1981 he founded UNIRAS Aps to address the industry with a more general-purpose raster graphics software approach. UNIRAS A/S, UNIRAS Ltd and UNIRAS Inc became world-leading suppliers of Visual Data Analysis and Presentation graphics software for scientists and engineers with a revenue exceeding $25 million in 1987. UNIRAS was also a supplier of raster software to IBM, Tectronix and Versatec. When Advanced Visual Systems (AVS) acquired UNIRAS in 1993, he was appointed to the position of AVS Fellow to recognize his contributions to the evolution of AVS. He has been a member in various graphics metafile committees supporting CGM, GKS etc. He has coordinated several large EC funded projects INDEX, NOVICE, CONTENTS, SmartDoc and MUSIC in the domain of knowledge-based information visualization and result in large academic and industry network. These projects developed innovative Web based visualization technology based on both VRML and downloadable Web components. CONTENTS and SmartDoc are early novel EC research projects to create dynamic visualization documents based on Storytelling (see publications below).He has also consulted with the EC Commission as a technical expert in visualization. He has published more than 200 technical papers and several books in visual computing and visualization application areas and has been a frequently invited keynote speaker at international conferences. At SIGGRAPH 93, he was elected "pioneer of computer graphics" based on his ground breaking research together with professor Hertz in raster graphics. In Sept 1999, he returned to academic research and was appointed professor at Linkoping University, Sweden to continue his research now with focus on geovisual analytics and storytelling - completed a recognized EC-funded visual flood forecasting system (MUSIC) in collaboration with University of Bologna. In May 2008, he founded NCVA (Swedish National Center for Visual Analytics) with financial support from the Swedish Knowledge Foundation (VINNOVA) and commercial partners Unilever Research Port Sunlight, Ericsson Research, SMHI, SCB, etc. and in close collaboration with OECD created awareness and interest for advanced geovisual analytics in the statistics domain. This achievement resulted in an honourable invitation by OECD to become an “associate” member, domain expert and supplier of strategic Web visualization tools to OECD. In 2010, NCVA introduced innovative technique for Statistics Publishing on the Web with an objective to deliver interactive visualization to educators and their students to get informed and at the same time participate in increasing the knowledge on how life is lived and can be improved. He still gives invited presentations at international conferences about Statistical Visualisation and Storytelling (Europe 2020, NTTS, Nordic Statistics, VINNOVA Big Data, iDays Open Data, etc.) In 2007, the Swedish Museum of Science created and published his life story based on a collection of interviews available at He has long experience in “Big Data and Open Data” issues and implementations collaborating with leading edge users at OECD, EUROSTAT, SCB, IMF, Swedish government and Regional Swedish organizations.
