### Home
I'm associate professor (maître de conférences) at the [Institut Élie Cartan of Lorraine](http://www.iecl.univ-lorraine.fr/).
I am a member of the partial differential equations research group and the [SPHINX](https://www.inria.fr/equipes/sphinx) research team (INRIA Nancy).

My research activities focus on the study of mathematical systems modeling the dynamical interaction of a fluid with a rigid or deformable structure. The motion of rigid solids immersed in a fluid or swimming fish are two examples of such systems.
More precisely, I mainly address the following issues...
### Modeling
About this process, which consists in deriving a system of equations from physical principles, I've compared, for fluid-structure interaction systems, the Newtonian approach (of Classical Mechanics) to the Lagrangian formalism (of Analytic Mechanics).
### Biolocomotion
The biolocomotion is the study of fish and aquatic mammals locomotion. I work on all of the features of this problem: modeling, well posedness of the mathematical equations of motion, control (with T.Chambrion), numerical simulations (with B. Pinçon).
### Collisions
I'm interested in studying the asymptotic behavior of immersed rigid solids when they get close and eventually collide with a wall.
### Detection
Fish are endowed with a lateral line, a sense organ allowing them to detect immersed obstacles. C. Conca and I work on inverse problems that consist in recovering the position and the velocity of immersed rigid solids, from some data of the fluid.
