Welcome

I am a senior research scientist (directeur de recherche) with the AVIZ project team at Inria, located on the Saclay / Université Paris Saclay campus, 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 non-traditional hardware as well as illustrative visualization that is inspired by traditional illustration.

p text-align=justify color=red I am currently looking for a PhD student with a solid background in computer graphics and/or visualization who is interested in working with me on the topic of Support of the Interactive Visual Exploration and Classification of Temporal Development in 3D Datasets using the Example of Cell Division Data. Please contact me by e-mail if you are interested or directly apply at the mentioned application site.
