Welcome

I am a senior research scientist (directeur de recherche) with the AVIZ project team at INRIA-Saclay, south of Paris in France.

I am member of the Scientific Visualization and Computer Graphics research group within the Johann Bernoulli Institute of Mathematics and Computer Science of the University of Groningen, the Netherlands. Since September 2010,

My research focuses on interactive scientific visualization and illustrative rendering, using methods from computer graphics, non-photorealistic rendering (NPR), and human-computer interaction. I am specifically interested in (2D and, in particular, 3D) interaction techniques for work with illustrative visualizations on large, touch-sensitive displays as well as illustrative visualization that is inspired by traditional illustration.

I am currently looking for good PhD students or post-docs with a solid background in computer graphics and/or visualization who are interested in working with me on topics in interactive visualization and illustrative rendering. Please contact me by e-mail if you are interested.
