I am currently a postdoc at Harvard University, working with Hanspeter Pfister. I did a one-year postdoc at INRIA Nancy, with Bruno Levy until January 2012, working on anisotropic remeshing of surfaces. I previously did a one year postdoc at UBC in Vancouver, supervised by Michiel van de Panne, working on displacement interpolation. I received my PhD in September 2009 at INRIA Sophia Antipolis, supervised by George Drettakis. I am particularly interested in geometry, realistic rendering, images, ...

New tech report on sliced transportation using both the Radon approach and random projections ; co-written with Julien Rabin and Gabriel Peyré, and advised by Hanspeter ; it is also a bit more mathematical.
We also received an honorable mention for the BioVis contest for our protein visualization tool Mu-8 (pronounce "Mutate") with Johnathan Mercer, Balaji Pandian and Alexander Lex, under Hanspeter's supervision and in the context of his CS171 visualization class.
The end of the semester is approaching for the CS109 - Data Science class I am TF'ing, and Math232a (by Mboyo Esole) and Math231a (by Hiro Lee Tanaka) that I'm both auditing.
Finally, I'm also joining CNRS as a junior research scientist in January in Lyon, between two geometry teams at LIRIS: GeoMod and m2Disco. I'm thus no longer looking for positions ! :)
I also created a small webpage with a few efficient mass transport (/EMD/1st Mallow distance/Wasserstein/Monge Kantorovich/Kantorovich Rubinstein/Hitchcock Koopmans...) codes I reimplemented or used. Tell me what you think!

Don't miss our new technical report on sliced mass transportation!
Also, don't miss my talk at Siggraph, presenting our video color grading method, on Monday, July 22nd, at 10am in the Anaheim Convention Center.
- April 29th, 2013
Our ACM SIGGRAPH paper Example-Based Video Color Grading (Nicolas Bonneel, Kalyan Sunkavalli, Sylvain Paris and Hanspeter Pfister) is accepted !
Our method makes use of cool differential geometry to color grade videos in a temporally consistent way. And speaking of differential geometry... the term is ending for Hanspeter's CS171 visualization class that I'm TA'ing and for the differential geometry classes I'm auditing (Math230B by S-T.Yau and Math132 by A.Cotton-Clay).
- December 18th, 2012
End of the term for CS 205 , and new tech report available on BSDF sharing.

Our paper Variational Anisotropic Surface Meshing with Voronoi Parallel Linear Enumeration is now online. Check it out if you are in need of fast and parallel Voronoi diagrams, possibly in very high dimension, or simply want efficient anisotropic remeshing.
I am now a teaching assistant for CS 205 - Computing Foundations for Computational Science at Harvard for this semester (this course is an introduction to parallel thinking and programming for computational sciences), and auditing S-C. Lau's Math230A differential geometry class.
- July 12th, 2012
Our IMR'12 remeshing paper got accepted (Variational Anisotropic Surface Meshing with Voronoi Parallel Linear Enumeration, Bruno Levy and Nicolas Bonneel). The pdf is not online yet.
I was also happy to be head teaching fellow for CS 171 - Visualization at Harvard this past semester.
- Januray 10th, 2012
I'm happy to announce that, on February 1st, I will be starting a new postdoc at Harvard with Hanspeter Pfister.
For older news : I was invited to give a talk for an annual meeting of the LIMA project in July 2011 - a project bringing together research teams working in graphics around Lyon and Grenoble (FR). I also presented our 2010 ACM Trans. App. Perception paper at APGV in August 2011. I also presented a demo of our VMV 2011 paper at the "Palais de la Découverte" in Paris (a science museum) in October. And finally, I went to Hong Kong to present our Displacement Interpolation paper at Siggraph Asia 2011 in December !
- August 9th, 2011
Our paper Displacement Interpolation Using Lagrangian Mass Transport has been conditionally accepted for publication at Siggraph Asia (ACM Trans. on Graphics).

I was ranked 5th for a full time research position at INRIA over approximately 125 candidates holding PhDs in various computer science disciplines. This does not allow me to get the position (there are 2 positions), and I'm thus looking for career opportunities, research positions in faculties or interesting companies. My research statement mainly involves Wasserstein spaces and mass transport - or how to deal with probability distributions (such as BRDFs, color histograms, character pose distributions, descriptor distributions for vision applications, etc.) in a principled way. I see this space of distributions as a Riemmanian manifold (see for example the excellent book from Vilani), where geodesics can be computed, where projection makes sense etc. : in short, where differential geometry makes sense. This is inspired by our last work (and to a lesser extend, by our EGSR paper on hair reflectance acquisition) where I realized that most blending operations performed on probability distributions just don't make sense and give rather poor results, while Wasserstein spaces solve these issues and give an exciting research direction!
For a more applied research and development industry, my skills (non-exhaustively) involve computer graphics, applied maths, C++/Matlab coding. To a lesser extent, computer vision, machine learning, mobile development on Android, and other programming languages (Java, Fortran etc.).

We released our last work on displacement interpolation as a technical report. This is an excellent topic to work on... Check the video and the project page!

After the Siggraph deadline, I spent a few days with some friends in the largest wind tunnel in the world, at Paraclete XP, NC, trained by the skydiving World Champions: the Team4Speed. Check the awesome video we did!
- December 6th/November 21th, 2010
I just accepted to be part of the International Program Committee for the Eurographics Symposium on Rendering (EGSR) 2011 and for the Graphics and Virtual Reality (GRVR) 2011 international conference.

We got the Best Paper Award at VMV for Proxy Guided Texture Synthesis for Rendering Natural Scenes over 82 submitted papers including 43 accepted papers!.
I will also start a new postdoc at INRIA Nancy with Bruno Levy from December 8th 2010.

New website! Our technical report has also been accepted as a paper to appear at VMV'2010.
- May 23rd, 2010
We released a great technical report on rendering sketched 3D scenes using photographs... Check this out here! You can also directly see the video on YouTube here.

My PhD thesis is now online. Download it now!
- September 15th, 2009
I just defended my PhD thesis "Audio and Visual Rendering with Perceptual Foundations". I will be a postdoctoral researcher at the University of British Columbia starting from December 2009 to November 2010, supervised by Michiel van de Panne.
