Professor of CAD/CAE and mechanical engineering at ENSE3/INPG: He developed, over the past 20 years, shape transformation and deformation methods for engineering simulations, in the form of high level operators incorporating engineering constraints such as aesthetics and quality finite element mesh generation. More recently, he introduced generators for non-manifold models, a new step towards high level models for simulating assembly tasks. In addition, he contributed to new interaction devices enabling to grasping objects or sculpt with virtual clay.
