About me

I obtained my Ph.D. degree from Grenoble University at INRIA in France in July 2011. My thesis document can be found here. Previously, I was a PhD student in the ARTIS team of INRIA under the supervision of Fabrice Neyret, working on very large and detaild voxel scenes rendering on the GPU for video game applications. I developed the GigaVoxels pipeline that proposed the use of pre-filtered voxel representations to efficiently render very large and detailed scenes as well as complex objects. During this thesis, I also did 2 summer internship at NVIDIA and I was also research visitor at Weta Digital.

I now joined NVIDIA Research in September 2011 as a postdoctoral research fellow. My NVIDIA research page
My research interests include realistic rendering, voxel-based representations, real-time ray-tracing and out-of-core data management, sparse voxel octree, GPU algorithm and complex GPU data structures.

I presented GigaVoxels as a talk at Siggraph 2009. The talk presented our GigaVoxels pipeline now fully implemented in CUDA as well as new results we got. I especially demonstrated a new cache mechanism fully implemented on GPU, as well as ray-traced soft shadows and depth-of-filed effects implemented very efficiently thanks to cone tracing taking advantage of our full 3D MipMapping approach.

GPU Working Group

I am particularly interested in GPU hardware and I am managing an INRIA working group on the topic.


In 2007/2008, I give a Computer Graphics course on image synthesis and real-time rendering for Master students at Grenoble University/INPG. This course include OpenGL advanced features, texture synthesis and CUDA programming.

Personal website

I am maintaining a technical website, containing various computer graphics projects I made during my studies or my free time.
It also contains a GPU blog with up to date news about various GPU related stuff and experiments I make.
