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.

News and Upcoming Events

October 2013	I gave an invited talk on visualizations on surfaces at the workshop Mobile and Breaking News: New Challenges for News Information Visualizations.
October 2013	We presented the paper “A Systematic Review on the Practice of Evaluating Visualization” at the IEEE Scientific Visualization conference in Atlanta. We also presented a journal talk on our paper “Bristle Maps: A Multivariate Abstraction Technique for Geovisualization” at the same IEEE VIS conference. Finally, we showed the poster “Illustrative Data Graphic in 18th–19th Century Style: A Case Study”.
October 2013	Together with Joaquim A. Jorge, I was the tutorials and workshops chair for ITS 2013. (:cellnr width=25%:) August 2013 (:cell:) Together with Amy Ulinski and Patrick O'Leary, I am organizing the Mobile Immersive Visualization workshop (WMIV 2013) at MobileCHI 2013.
July 2013	I presented a talk at the ACM/EG Expressive conference on our work on “Interactive Example-based Hatching”. I also presented a poster on “Illustrative Data Graphic Style Elements” as well as two Visual Showcase pieces—one each about the talk and the poster.
June 2013	My second “own” PhD student Lingyun Yu has successfully defended her thesis on June 3. Congratulations Yun!
May 2013	A paper by Daniel F. Keefe and myself on a research agenda for future interactive scientific visualization tools was published the journal IEEE Computer.
May 2013	Our article on “The State of the ‘Art’: A Taxonomy of Artistic Stylization Techniques for Images and Video” appears in the journal IEEE Transactions on Visualization and Computer Graphics.
April 2013	We presented our paper on “Weighted Graph Comparison Techniques for Brain Connectivity Analysis” at ACM CHI 2013 and received a Best Paper Award for it.
March 2013	Our visualization viewpoints article on “Data Visualization on Interactive Surfaces: A Research Agenda” has appeared in the journal IEEE Computer Graphics and Applications.

January 2013	A new book about non-photorealistic stylization has been published by Springer with two chapters that I wrote or co-authored: a chapter on the evaluation of NPR by myself and a chapter on stippling by Oliver Deussen and myself. Check them out!
December 2012	I started my new position as senior research scientist (directeur de recherche) with the AVIZ project team at INRIA-Saclay.
October 2012	Our paper on “Efficient Structure-Aware Selection Techniques for 3D Point Cloud Visualizations with 2DOF Input” received an Best Paper Honorable Mention Award at the IEEE Scientific Visualization conference (VisWeek 2012).
October 2012	The VisWeek 2012 submissions were quite successful: we presented the papers “Efficient Structure-Aware Selection Techniques for 3D Point Cloud Visualizations with 2DOF Input,” “Sketchy Rendering for Information Visualization,” and “Evaluating Sketchiness as a Visual Variable for the Depiction of Qualitative Uncertainty” in Seattle.
