I am currently a senior researcher at INRIA and the group leader of the REVES research group at INRIA Sophia-Antipolis. My research interests are in rendering for computer graphics and sound. My recent work is on image-based rendering and textures, perceptual rendering, and in particular audio-visual cross-modal rendering, interactive illumination, shadows, relighting and interactive rendering in general. My responsibilities include managing the group, supervising graduate students and coordinating/managing research projects.

I am currently associate editor-in-chief of IEEE Transactions on Computer Graphics and Visualization;  I am chair of the Eurographics Steering Committee for the Working Group on Rendering.
I was the chairman of the Eurographics Awards committee (2008-2013). From 2005 to 2007 I was a member of the Scientific and Technological Orientation Council (COST) of INRIA in charge of the International Relations working group. I was the recipient of the Eurographics Outstanding Technical Contributions award in 2007 (EG link), and also was nominated as a Eurographics Fellow.

Publications

My complete list of publications can found here (sorted by type) and here (sorted by year), and a list of the research projects of the group here. Recent publications include "Depth Synthesis and Local Warps for Plausible Image-based Navigation" (TOG, presented at SIGGRAPH 2013) and "Perception of Perspective Distortions in Image-Based Rendering",  SIGGRAPH 2013.
Students / Postdocs

I currently supervise three Ph.D. students: Sylvain Duchêne (VERVE project) who works on relighting, Emmanuelle Chapoulie who works on VR and Rodrigo Ortiz-Cayon (CR-PLAY project) who works on image-based rendering. I am currently hosting Stefan Popov as a postdoctoral fellow (ANR ALTA project), who works on global illumination.

Teaching
Since 2006 I teach advanced computer graphics at the Ecole Centrale de Paris, and since 2012 I teach graphics (with A. Bousseau) in the Sophia-Antipolis International M1 program. I also teach in the Cannes MAPI ("Management for computer games" Masters).  I taught computer graphics (with N. Tsingos & S. Lefebvre) in the Masters programme IGMMV, and in  the ENA/Nice Sophia-Antipolis M1 program and I was the organiser and a lecturer of the Image Sythesis course (2001-2007) at the Institut Supérieure en Informatique et Automatique (ISIA) of the Ecole de Mines de Paris at Sophia-Antipolis.
Current Funded Projects
  • VERVE an EU IP FP7 project on virtual reality technologies for the elderly and excluded.
  • CR-PLAY and EU FP7 project on image- and video-based techniques for games.
  • ANR ALTA  a French national project on global illumination.
  • EA CRISP:
  • INRIA funded "joint research team" (Associated team) with UC Berkeley (M. Agrawala, R. Ramamoorthi and M. Banks).
Selected Past Funded Projects
  • CROSSMOD was an EU Open FET IST project on audio-visual crossmodal rendering which I coordinated from Dec. 2005-Dec. 2008. The partners were Univ. Bristol, UK, CNRS, IRCAM France, TUW, Austria, CNR, Pisa, Italy and FAU, Erlangen Germany. The goal was to  better understand cross-modal effects by specific initial experiments and then to develop new algorithmic approaches exploiting cross-modal effects for better audiovisual display.  See the web site (http://www.crossmod.org) for all the results of the project, which was successfully evaluated in Dec. 2008.
  • ARC NIEVE:
  • INRIA funded collaborative project with BUNRAKU and IRCAM on emotion and navigation in virtual environments.
  • CREATE was an EU IST 5th framework R&D project, on constructivist mixed reality for education and design. I managed the REVES/INRIA contribution, which has concentrated on the development of the rendering/display tools, and various aspects of capture. We were also in charge of the coordination with the Mission Tramway in Nice, which was our urban design application for the project.
  • ARCHEOS  was an INRIA financed 2 year research project (Action de Recherche Concertée) on non-photorealistic rendering for archeology. I was in charge of the overall coordination of the project.
  • I was project coordinator of the first phase of the SIMULGEN  ESPRIT Open LTR project, with partners from the Max Plank Institut, the University of Girona and Lightwork Ltd. 
  • I participated actively in the ARCADE  ESPRIT Reactive  LTR project under the responsibility of F. Sillion. The partners of this project were IGD in Darmstadt and LightWork in Sheffield.
Other Activities
I was technical papers chair for SIGGRAPH Asia 2010. I co-chaired the papers program for the Eurographics Conference 2008, in Crete, with Roberto Scopigno. I also co-chaired the papers program of the Eurographics Conference 2002 with Hans-Peter Seidel, and the Eurographics Workshop on Rendering 1998 with Nelson Max. I have served on the Eurographics Workshop on Rendering programme committee (now the Symposium) since 1995, and I have served on several times on other program committees, including Eurographics, SIGGRAPH and SIGGRAPH Asia PC's.

Short Bio (for general use)
George Drettakis graduated from the Dept. of Computer Science in Crete, Greece, where  he participated as an undergraduate in European projects at ICS/FORTH.He obtained an M.Sc.and a Ph.D., (1994) at the Dept. of C.S. (Dynamic Graphics Project) at the University of Toronto, Canada, under the supervision of Eugene Fiume. He was an ERCIM postdoctoral fellow in Grenoble, Barelona and Bonn (94-95). He obtained a permament Inria researcher position in the iMAGIS group in Grenoble in 1995. He obtained the degree of "Habilitation" at the University of Grenoble (1999). In 2000 he moved to INRIA Sophia-Antipolis, where he founded the REVES research group, officially created in 2002. He became a INRIA Senior Researcher  2003; and DR1 (full professor equivalent) in 2008. He received the Eurographics  (EG) Outstanding Technical Contributions award in 2007 (EG link) and is an EG fellow. He was technical papers chair of SIGGRAPH Asia 2010, is co-editor in chief of IEEE Trans. on Computer Graphics and Visualization and leads the EG working group on Rendering. He has worked on many different topics in computer graphics, with an emphasis on rendering. The first part of his career concentrated mainly on lighting and shadow computation. In the first years of the REVES group he also worked on 3D audio and in particular perceptually-driven algorithms. In recent years he has worked on image-based rendering and relighting,  textures, perception for graphics, weathering simulation,virtual reality and 3D interaction.
