Short Biography (CV)

Ivan Viola is a Post Doctor research associate at University of Bergen, Norway. He was formerly associated with Vienna University of Technology, Austria, where he received M.Sc. in 2002 and Ph.D. in 2005. His research is focused on development of novel methods for automatically generating expressive visualizations of complex data. Viola co-authored several scientific works published on international conferences such as IEEE Visualization, EuroVis, and Vision Modeling and Visualization and acted as a reviewer and program committee member for conferences in the field of computer graphics and visualization. Recently he has co-organized series of tutorials on illustrative visualization. He is member of Eurographics association, NorSIGD, IEEE Computer Society, VGTC.
