Short Presentation & Bio:

I am Professor of Computer Science at Ecole polytechnique, part of Institut Polytechnique de Paris. My research lies in the Computer Graphics field, and revolves primarily around 3D Modeling, Deformation, and Animation of virtual content, with a keen interest for Real-Time Efficiency, Interactivity and User Control. My previous research contributed to the Modeling and Animation of Virtual Character, Developable Surface, 3D Garment models, and to the Simulation of Natural Phenomena. My methodology typically couples procedural approaches and lightweight physics, with the use of appropriate geometrical representation featuring for instance hierarchical level of details and field based representations. My work principally find applications for entertainment production recquiring efficiency and interactivity such as Animation Cinema, VFX, and Games, with publications in Graphics journals and venues including SIGGRAPH, Eurographics, SCA and MIG. I additionally enjoy collaboration with other disciplines such as Medical Sciences, Math, or Design.

I obtained my PhD in 2011 from Grenoble University. I also hold an Engineering Degree from CPE Lyon in Computer Science and Electrical Engineering (2007), a Master in Optics, Image and Vision from Université Jean Monnet at Saint-Etienne (2007), and a Habilitation (HDR) from Grenoble University (2017).
I am currently serving as Vice-President of the Department of Computer Science at Ecole polytechnique (DIX), and leading the VISTA research team. I was conference chair of SCA2017, program chair of MIG2021 and IMET2023, and I am regularily part of multiple IPC such as Eurographics, Pacific Graphics, SCA, MIG, Siggraph and Siggraph Asia Posters, Shorts and courses. At the national level, I have been part of the sterring commity of AFIG - French Association in CG since 2015.
I am widely involved into education, encompassing teaching at various level, including master and bachelor programs in CG, 3D animation, as well as Web Programming, and engage in tutoring numerous student projects. I am also coordinating the Image, Vision and Learning specialization at Ecole polytechnique, and actively contribute to the organization of the Interaction, Graphics & Design Master program at IP Paris. I further enjoy proposing and developing open-source content and softwares in order to facilitate accessibility and re-usability to students and the scientific community. These include a set of open-source online course slides and practical exercises in CG and Animation, and an entire programming library framework (CGP). I am also the main developer of open community-driven listings for existing Graphics companies, available positions, french research teams, and educational content.

Research

I am researcher in Computer Graphics working in 3D Modeling, Deformation and Animation of virtual content with a specific focus on efficiency, interactivity and user control. The general objective of my work is to develop novel methods to support and improve creativity, representation, exploration and experimentation with virtual data, possibly adapted to various application domains.

Application Domains: Entertainment (Animation Cinema, VFX, Video Games, AR/VR), Natural Sciences (Medical, Biology), Design & Fabrication (Fashion, CAD, Architecture).
