I'm a 4th year PhD student under the supervision of Fabrice Neyret.

Research themes

I work on problems related to computer graphics and I am especially interested in photo-realistic and physically-based rendering. One of the main goals of my work is to improve the efficiency of rendering by simplifying details that are smaller than pixels or that are unnecessary for other reasons (out of frustum, hidden, out of focus). I design new tools for simplifying complex 3D assets while preserving their appearance in rendered images (level of detail (LoD)). For example, I work on methods that allow for replacing heavy 3D meshes (e.g. trees) by lighter representations so that there are no differences in final images.

Interests: rendering, phase functions, LoDs, sampling, mesh simplification, texture filtering, optics, volumetric models, path tracing, aliasing

My CV: CV.pdf

2014-2018: PhD candidate at Univ. Grenoble Alpes

April 2018: We won the Günter Enderle Best Paper Award with our paper "A new microflake model with microscopic self-shadowing for accurate volume downsampling" at the Eurographics 2018 conference.

2017 (October-December): Intern at the Walt Disney Animation Studios (Burbank, CA, USA). I worked on automated LoDs for production assets.

2015 (July-August): I worked at Weta Digital (Wellington, NZ) in the team in charge of LoDs for production.

2011-2014: student at the ENSIMAG, master degree in mathematics, modeling, image processing and simulations.

2014: master degree thesis with Fabrice Neyret on real-time galaxy and dust clouds rendering (local model for single scattering, appearance of heterogeneous dust clouds, procedural noises).
