Alexandre Munnier

### 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). ### Contact Postal address Bureau 211 Institut de Mathématiques Élie Cartan Université de Lorraine B.P. 239 F-54506 Vandoeuvre-lès-Nancy Cedex France Phone (33) (0)3 83 68 45 41 Email alexandre.munnier\[at\]univ-lorraine.fr Research -------- 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.
