About Me
I am a Maître de Conférences (Associate Professor) at the Aix-Marseille University, in Marseille - France. I am associated with the Laboratoire de Mécanique et d'Acoustique - LMA. My domains of research are experimental and computational solid mechanics and mechanical engineering. My work is to combine theoretical, computational and experimental methods to gain deeper insight into the non-linear behavior of materials and structures. The overall goal is exploit material and geometric non-linearities to design novel materials with tunable exceptional properties.

Projects
ANR - SAMBA (Silicone Architectured Membranes for Biomedical Applications) 2012-2016
This project takes its source in an array of works aiming at designing highly deformable anisotropic membranes for medical applications.
The silicone rubbers are highly deformable biomaterials widely used by surgeons for their mechanical properties controlled by their
crosslinking rate. In current medical applications, the properties of silicones are homogeneous and isotropic. In the present biomimetic
approach, our researches aim to provide the clinician elastomeric membranes whose local properties can possibly be non-uniform and will
be fully controlled during their elaboration, both in stiffness and anisotropy.
Partners: IMP (Lyon)/ MATEIS (Lyon)
ANR - ANiM (Architectured Ni-Ti Materials) 2010-2014
This project aims to develop a new category of innovative materials combining the intrinsic and novel properties of
Nickel-Titanium shape memory alloys with purposely engineered topologies allowed by the notion of “architectured materials”. More specifically,
we aim to create architectured materials constituted of NiTi wires and tubes. Using fibres cut from thin wires, we will create non-woven random
2D textiles, 3D blocks of low solid densities, and more complex designed architectures. With thin-wall tubes we will create regular cellular
materials. To realise these unique structures we apply a range of innovative materials processing techniques, such as plasma sintering,
electric resistance welding, diffusion brazing, and silicone elastomer infiltration.
Owing to the versatility of their structures, these materials offer a range of novel properties that have not been
available to date. Combining the unique strength of the material architectures and the novel properties of NiTi, this new category of
“smart” materials is expected to have a strong impact in the existing shape memory alloy industry, by drastically enhancing their design
capability and competitiveness.

ANR - RAMMO (Eel-Like Robot with electric sense) 2007-2011
This ANR Project aiming at the design, construction and control of a 3D eel-like robot with electrical sensing that is usually used by the electric fishes.
The robot is composed of 12 vertebras connected through a rotation free joints. The whole robot is covered with a skin that is especially designed
in order to avoid perforation due to the water pressure while allowing an easy swimming oriented ondulations. My role in this project is to design this skin,
composed by a special silicone rubber material.
