There is no question that the material world is hierarchical.

1989 – 1993..6 My research path began when I studied in Combinatorial Mathematics (Montreal, Québec) focusing on the study of words (sequences), mainly Lyndon words – you see my name here and there on the wikipedia page for Lyndon words. I still publish now and then a paper with colleagues who generously welcome me in their project (thanks to S. Brlek and C. Reutenauer – my former PhD advisor).
The amazing thing is that these words encode trees, and the bottom line is you need to draw them to understand how they are built. Which I did – a lot.
1993..6 – 2000 This is when I made the decisive jump into Information Visualization, more decisively when working as full time researcher with I. Herman and M.S. Marshall at CWI in Amsterdam. These were intensive years of research, with our group putting graph visualization forward in the InfoVis community. Our star publication was the 2000 survey on Graph Viz which is still quite cited these days (1250 citations according to Scholar on Dec 24/2013).
1999 – I got the French HDR (Habilitation à Diriger des Recherches) from Université Bordeaux I, on December 7, 1999 (under the guidance of Ivan Herman, CWI, Amsterdam and Maylis Delest, Université Bordeaux I).
2000 – 2007 Back in France as a Professor at Université Montpellier 3, affiliated with CNRS UMR 5506 LIRMM. These were great years spent with colleagues at my teaching department, while promoting Information Visualization both in the French academia and in the industry.
2007 – Professor at Université de Bordeaux, affiliated with CNRS UMR 5800 LaBRI. I was also part of INRIA and headed the GRAVITE team (2006 – 2012). Putting up the INRIA GRAVITE team was a wonderful experience. My very own perspective on running an INRIA team is to define a collective strategy aiming at the best possible research results while promoting our work towards industrial actors, as well as academic partners in other areas.
