I am a Research Scientist in computer graphics at NVIDIA Research. I joined NVIDIA in 2011 after obtaining my Ph.D degree from Grenoble University at INRIA in France. My research interests include real-time realistic rendering, global illumination, alternative geometric and material representations (especially voxel-based), ray-tracing, anti-aliasing techniques, distributed rendering, GPU algorithm and complex GPU data structures, as well as out-of-core data management.
