Teaching and Research Assistant in Applied Mathematics at École Centrale de Marseille (2018-2019).
I work on the propagation of mechanical waves in nonlinear materials. In particular, I study the nonlinear dynamic behavior of viscoelastic solids (theoretical and numerical aspects). This research has various applications in engineering, e.g. in geophysics, biomechanics, nondestructive testing and materials science.
PhD thesis (2015-2018) : Modeling wave propagation in nonlinear solids with slow dynamics.
